Acorn to Arabella - Journey of a Wooden Boat - Episode 29: Lead Contamination and our Keel Pour
HTML-код
- Опубликовано: 25 июл 2024
- After the video of our lead keel pour came out, we received a lot of comments regarding the safety of the pour and about concerns or contamination to the surrounding area. We did our best to get information regarding such issues and went as far as calling the EPA number as well a several local agencies, all to no avail. We basically kept getting told to stop wasting their time about this... so we took a friend up on her offer to inform us on what she knows and get the soil tested!
As you can see from the video, we did not create any concerning contamination of lead to the soil, nor to ourselves. The soil levels were at 7mg/Kg and the accepted EPA amount is 400mg/Kg.
We put out a call for any local black locust trees that may need removal. If you are interested in our offer to come cut it down and clear the remains (including the stump) and are within 1hour of Granby, MA (01033) please get in contact with us at: acorntoarabella@gmail.com
Please be sure that the trees are Black Locust and not some other variant such as Honey Locust. Here is a link that would be of use if you need help identifying your trees: gardenerdy.com/locust-tree

Acorn to Arabella is a boat building project taking place in Granby, Massachusetts. Steve and Alix started as amateur boat builders building their own 38' wooden boat in their backyard: designer William Atkin's Ingrid with a Stormy Petrel's gaff rig. These videos follow the journey from tree felling, to lumber milling, to lofting, to the lead keel pour and beyond-sharing details of the woodworking, carpentry, metal smithing, tool building, and tool maintenance that wooden boats command. This ultimate DIY project will continue well past launch, when they will travel and learn to cruise aboard the boat that they've built. Just kidding about all that, this channel is about a Siberian Laika named Akiva.

Great job Sarah. Unfortunately, those who are freaking out over the lead pour won't let pesky science and facts get in the way of a good panic.
I wonder how many of those people whining about the pour drive cars...
or fly in airplanes...
or wash cleaning products down the drain...
or wear clothes made of synthetic fabrics...
or throw away plastic containers...
or have asphalt shingles on their house...
or...
Libtards, man. They don't like to let facts get in the way of how they feel, and how they feel is exactly how everyone else should feel. Or else.
The best comment so far - good luck Dave!
"those who are freaking out over the lead pour won't let pesky science and facts get in the way of a good panic."
Don't be a hypocrit, you didn't know the science behind it either, and you're just doing a childish "told you so" after proven right.
vinny142 how do you know what he did and didn't know? Even if he didn't know the science of it, he knows now. But his statement is true. If you teach those people the science they'll just deny it.
I'm a professional environmental scientist and Sarah is on point. The Arabella project was relatively safe and environmentally sound. There is always a balance between the environment and the needs of society. The Arabella project found a good balance in their working with lead. They used personal protective equipment and were good with preventing any significant amounts of lead into the ground. The whole lead question has been blown out of boundary.
So true and very well put.Considering how old the house and surrounding properties are I'm sure that there's more contamination from old paint then they could possibly have done.Like you said they found a good balance of safety for a home brew project. Now I'm no safety freak but I'd have shaved if it was me,though again that is for him to decide how much personal risk he wanted to take and not for some armchair warrior sitting home to decide. As far as their soil levels go,I've seen much worse around Victorian era homes than they have from the lead work on the keel.
Yep. A good shave before wearing the respirator is important. And choosing filter cartridges for metal fumes is also key. The wrong filter cartridges won't do anything to remove fumes from the air.
People think solid lead is as dangerous as asbestos or uranium, that by just being around it invisible particles are going to be in the air and kill them. It is not solid/liquid lead that is the problem. Dissolved lead compounds in water and lead vapour in air are the issues. Both of these require heat and/or chemistry to create from solid lead. Solid lead is basically inert. It doesn't readily degrade into oxides/nitrites etc without help. That is one of the reasons we use it so much. It is very resistant to corrosion by many chemicals and fluids.
The reality is his blood lead level was not checked before the pour, so we don't know if he may/probably accumulated most of that lead already earlier in life. Car exhaust, paint, pipes, etc. As to this situation, solid or even liquid pure lead are not that dangerous. You pretty much have to eat it to get any into you. Vaporized lead is a different story. Lead dust on a cigarette for instance, or overheating the lead during the pour. Then the vapours can get into your lungs. This is where you intake lead fast.
They did a great job protecting themselves from this. They controlled heat to prevent boiling and vapor production, and wore a respirator.
My only concern is if they left any lead shavings on the ground while sawing. If someone built a campfire there in the future, it could vaporize the lead and ruin the singalong.
SouthJerseySound The Navy uses respirators and allows breads. There are respirators out there for this purpose!
provide your credentials, or you are just a person on youtube saying they know when they dont
Great that you guys pick up on the points raised and address them. Andy UK
Bravo! I'm going to refer Safety Sallies to you guys. :)
Always funny running into you guys over here! And during this video I couldn't help but think how you get the same lead safety paranoia comments, but instead you guys mostly just ignore it lol
@SV Seeker
Please don't! haha
SV Seeker love your channel can't wait to see your boat in the water
why is a safety first/safety is paramount attitude met with such distain? Hi my name is Safety Sally sorry for being concerned that what appear to be really nice people might be poisoning themselves?
MrAwsomeshot Could you be any more oblivious?
Nice job, Sarah. You are well spoken and articulate. Thank you for sharing this information.
Very informative as usual. Interesting to see the effect on you and the local environment, glad your both OK. Good work Sarah! Always good to surround yourself with intelligent people.
Well spoken Sarah, great job giving us the facts...Very interesting!
Now that is how a thinking person deals with concerns from lay people. Concise and to the point. You gentlemen are a breath of fresh air. Thank you, Sarah! Ah,Black Locust. One of my favorite trees. Nitrogen fixer, iron wood. Delivers more BTU's than Hickory and the blossoms can be mixed in pancake batter. I only hope I'm still in this mortal vale when Arabella dips her prow in the northern seas!
Thanks!
Sarah was a big help in expanding our knowledge. When she started nerding out (we mean that in a positive way) at the party we knew we had to get her to come explain it for everyone who cared to listen.
Nicely done. She was very credible. Glad you responded to the concern of the viewers.
Tee Jay they didn’t need to. Anyone with some common sense and basic knowledge will know this.
My father was a typesetter working eight hours a day, five days a week for 30 years with led before he got symptoms of led poisoning. So guys you are well out the woods. Good luck!
Legend. Really informative and panic free narrative. Nice to know my two favourite "RUclipsrs" are not going to die of lead poisoning. SO DON'T FALL OUT OF A TREE......
itsnotmeitshim did you know that the common houseladder is far more likely to cause a deadly injury than all the woodworker hazards combined? 😁
And don't let the tree fall on you, either.
Excellent presentation, I have been curious regarding this. Thank you as well, Sarah.
This is a very good video, she explains things very well and seems to know a lot about this theme. Congratulations to Sarah. Keep on going guys.
Excellent video. Thank you for truthful information on these issues.
Appreciate your response to the skeptics, you did a marvelous job. Build the boat, the skeptic types will just have to live with it. JD in MO
Thanks to all. Good info to keep in mind if I were to ever build my own boat.
Your levels of response and inquiry are excellent!
Thanks! We do try!
Thank you Sarah and Acorn to Arabella for a very informational video. It's great to see science used as it is intended. Keep up the great work and videos.
Thanks and will do!
Really great to see you guys being proactive about addressing peoples concerns (even if they're a bit ridiculous). Good luck with the Black Locust search, the wood is pretty incredible, my family farm back in Jersey has fence posts made of it still standing 30+ years after being put into the ground.
Locust is supposed to last 2 years longer than stone =)
Great video, very thoroughly done. I love the calm presentation. So glad I found this channel, interesting videos and well presented. Keep em coming!
Thanks and we will!
I did dynamic balancing of industrial rotors for over 30 years which involved a lot of lead melting. Wore protective gear and had annual blood work. No problems. Of course, respect the stuff!
Respect the stuff. Exactly. Not fear, respect.
Well done for taking the time to engage with those concerns and provide some background information and explanation. I'm sure it would have been way easier to just brush off those comments if you folks were sure of what you were doing yourselves, but you took the time, and spent a few dollars, to provide reassurance and a learning opportunity.
This is what you call a worthwhile post.
Back in my teaching days we called it "a teachable moment". We are learning a lot and are happy to share what we have learned.
You just answered my question about lead as far as spoil and it getting into a plant or something that was plant as far as for food. Thank you. Keep up the great work guys
Well done, Sarah! Concise, understandable, and to the point.
Guys I want to commend you for responding to the naysayers who too often let emotion leak out of their pie holes. I was trying to be more polite but... I spent 28 years in the nuclear cleanup and nuclear materials processing industry and retired in great health and fortune. Over the years I have dealt with many hazards including lead, PCB's and asbestos and I have had many experiences dealing with the emotional call out by detractors of that industry. You definitely did the right thing in talking to Sarah, and in my opinion you went over the top in taking soil samples and proving what you did. You taught a lot of people a great lesson and hopefully the naysayers will use a bit of critical thinking before they shout out again. More power to you guys and hopefully I stop by and see the project one day. You have created a great thing here.
I love you guys! This was brilliant....
Kudos on following up on this issue. Keep up the great work!
Thanks! will do!
Great job in employing her knowledge BEFORE the pour.
Great video and thanks for responding to the publics concern regarding environmental responsiblity.
Thanks! It was our pleasure, people were and are very concerned. Hopefully they look into the research and see that lead is a concern but the chances of us poisoning anything are really really small.
Glad to see you all are going above and beyond reasonable measures of testing and disproving the myths that may have come up in the pour video and other lead-related videos. Unfortunately, lead has a pretty crappy 'brand' right now after the ongoing use of lead pipes and contaminated water in the Midwest right now. Fortunately, like your scientist said, it's not that easy to get 'poisoned' by lead.
This is really interesting to know. Thanks for putting the time into exploring this in so much detail.
Excellent insight and information. Some will be enlightened, some will be forever ignorant.
Very impressed with your level of responsibility to your community and the concerned voiced. I have never done a lead pour, but was very impressed with the lengths you guys went to to make sure things were safe. Sarah doing the soil samples and explanation was very informative. I really enjoy the process and watching how you two tackle it. Can't wait for the finished product, as my dad was an interior finish wood wright for a boat company for 12 years back in the 60's before they went to fiberglass and metal. He is now 84 and if he is still around when your done I hope to show him a fine looking boat that was drawn up the year he was born.
Thank you!
We hope to meet him at the launch!
Its sad to hear some peoples negativity, especially after all the hard work you put into salvaging all that lead and then recycling it into your keel. But for me personally I have learnt a lot from your videos. Thank you for sharing your knowledge.
You are very welcome! We are learning so much ourselves and it's great to be able to share what we are learning.
Thank you for this! Awesome! I got some new wrinkles in my brain!
I am in mid-MD and black locust are the primary spring-blooming source tree for nectar for our honeybees. During May the landscape is covered with black locust trees covered with fragrant white flowers that my bees just love!
It says a lot that you took the time to address your viewers concerns about Lead Contamination. Excellent Video!!
Thanks!
What a wonderful young lady. I love to see women in the sciences. Thanks for coming out, miss.
That would have to be some old growth black locusts in north central Kentucky. Around here a black locusts might reach a full hug girth in close to 200 years or more. Good luck. Glad all your lead numbers came out so well.
We have heard of locust from NY that looks like Douglas fir it's so big and tall and straight. We have a couple leads on locust and hopefully will have some logs here by May.
Acorn To Arabella cool. Its amazing what a few hundred miles can do to differentiate growth of a species. I've got seven black locusts along the edge of my yard that are about 90-120 feet high and I can reach around them just fine (about 14-16 inches in diameter). If I wasn't outside of your radius, I'd offer those to Arabella if you took down one dead oak by the corner of my house. (I keep the oak for my projects.).
good video by the way . i learnt some new things , well done
Wow, too bad I live in Michigan, I have several. Good luck on your search!
"Here is the shovel. I'll let you do this, you're the expert!"... you're killing me
Good job. It's refreshing to see young people using facts and logic to make decisions rather than emotions and group hysteria.
Nice job, Sarah. And thanks, guys, for giving her the opportunity to address this issue on your platform.
One thing that could have been added is the actual effects of lead poisoning. We all know it's bad, but why?
Fun fact: The Latin word for lead, plumbum, is the origin of the English word Plumbing.
Very well done Sarah. I'm 73 can you imagine how much water I've drank through lead pipes since 1945? I'm still here.
That's survivorship bias though. You only see people who are still living. You don't see all they people who drank lead and died prematurely from it. It doesn't make drinking lead safe.
pancakepuff45... Exactly. You get the same argument from people that smoke. They all "know" or "know of" some guy that's 98 years old, smoked all his life and is healthy as a horse. I'd get this crap argument from my dad (who smoked). He died a year ago due to lung/heart issues attributed to smoking for 50+ years.
That said... The young lady in this video is on the ball. Excellent analysis/explanation of the science. Hopefully panic and outrage have been averted.
Lol did you listen to her talk about lead and water
I agree.......Lot's of whiny safety-sally's these days. Lot's of misinformation today thanks to the internet.
Lead pipes are no problem as long as the PH of the water is controlled to 7 and a bit below. When it is allowed to go alkaline like in the case of flint Mi. It dissolves the lead on the pipes and flows to the faucet. Bad. Most water treatment systems keep the water at an appropriate level d thus no problem, , even with lead pipes. Much hysteria tho.
Nice work guys, very responsible. I am extremely impressed! I have been watching your videos (and loving them!) and knew that environmental contamination due to lead would be negligible. I have lead poisoning myself, and it is not pleasant. I was on chelation therapy for two years. However, this was due to lead paint, which is much, much, much more bioavailable.
Come to New Zealand and build a ship out of Totora or Rimu! My parents had a barn made out of totora (untreated) which was over 200 years old when we pulled it down. The totora was still solid as (including the piles!). I have since made garden furniture and a compost heap out of the recycled totora.
Kia Kaha!
Thanks! Glad you have been enjoying following our journey.
New Zealand is certainly on the short list of places to visit. Some of the more tropical hard woods are amazingly resilient. The closest we have is probably black locust. The old timers say it lasts 2 years longer than stone.
Sorry to hear about your lead poisoning! That does not sound like a good time.
Thank you, well spoken, and provides back up, pretty girl also. I'm 79 and Joe has not drank from lead pipes, only galvanized, black iron and copper.
What?! The sky didn't fall?
PREPOSTEROUS!!
Hey, I am a retired board certified industrial hygienist and am available to answer questions and advise on all this health hazard stuff. Free offer. Sarah did a very good job on explaining. And glad that you came back with low blood lead. Regarding others, the only other thing I would say is that ingesting is a frequent source of exposure for lead and if people were eating and/or creating dust in the area they could have got a dose different than yours. Anyway, good job. SV seeker did some pouring also.
Thanks for the offer!
Feel free to respond to as many comments as you like! =)
Everyone who was there was warned quite heavily about the risks and they were all able minded adults. I believe they were all careful and we did encourage lots of hand washing.
You guys sure have it covered! You make me want to go get my blood checked! At 57 I've been building race cars since I was 20 and the amount of crud I've ingested (I can only imagine) I will say however you have proven one thing (if not many things) that information is key! I'm sure you guys got hammered by some far left (way out there far left!) people that wanted to put you in jail for doing what you did. So good on you for getting the correct info to the people.
real glad that bachelor holder could come explain this right..
Well played guys!
Awesome video, i'm into classic cars and have had envirowankers hassle me for driving "dirty polluting cars", they usually STFU when you explain how a catalytic converter works.
once you convert an older cars head to use non leaded they are very clean, considering the limited use of the vehicle.
Well played young Stephen, well played :)
Great video. Will look for black locas
You guys are awesome! I love you even more and Sarah is awesome too! I LOVE SCIENCE!!!!!
Thanks!
Science is pretty awesome!
Impressive response.
Thanks!
I must admit a little concern about your use of lead, specially for your own health. But, by watching you guys for some time now, I was reassured by your work ethics and sound values. Kudos, guys.
And thanks to Sarah to "clean the air" on the subject with clear, indisputable scientific facts. Brilliant. Well done.
PS I've been watching the tv series This old House for decades. Great guys but they really go overboard when they find lead or asbestos in/on an old house, some dating back to the 18th century : Of course, leaded paint was used then! So they go to the extent of publishing Warnings to the neighbourhood, biohazards placards everywhere... the works! Wrapping the whole house with plastic sheets, vacuum system, guys in quasi-nuclear safe suits etc.
No wonder undocumented lambda citizens get paranoid on lead poisoning !! Common sense should prevail, like you did !
Thanks!
We did a lot of research before we messed around with it but never expected the backlash that we got. Had we anticipated the concern we would have taken greater strides to mitigate them in advance. Lead is certainly a concern for health and there are reasons we are moving away from it's use in many areas but it has become a bit of a buzz word lately.
that beard is looking so much better than before, nice!
Awesome!
Respect for having done this. It's not what others would have done. Glad to hear you and the environment is alright. Now to round this up, why not ask cody from cody's lab (channel) if and how much pollution through gas has occurred?
Great video guys! I learned a lot about lead contamination and that's super neat. One thing though - In the description it says "7mg/Kg" were your leads soil levels, so ya missed out the "4" before it if the numbers in the video were correct. Thanks again!
Those who know nothing about lead, think any lead will make them mad as a hatter, however you are correct in your explanation. Lead pipes, vaporized lead, in gasoline, and lead in paint were the main causes of toxicity in humans. Now for the facts, I saw the pour, and there was minimal,if any, lead that went to ground. The milling of the keel was isolated and I assume was disposed of in the appropriate manner. Thanks for your update.
Yes, we were careful with the lead from milling and took it all (plastic, suit, shavings..) to a local hazardous waste facility to be disposed of properly.
The only caveat is the prolonged exposure to lead via old pipes. Leads pipes are perfectly safe to use for 100 years as a source of drinking water as they scale or calcify very rapidly. The water doesn’t contact the lead. The recent problems some communities have experienced is converting from chlorine water treatment to chloramine water treatment. The pH difference absorbs the calcium and exposes the lead. Any municipal problem with lead is directly related to treatment changes. (Civil Engineer)
That is exactly what our research into the matter has turned up. Thanks for sharing!
Thank you Sarah for the info. Smart and attractive too. Guys, good luck hope you find the Black Locust your looking for. Y'all keep up the good work!
Wonderful follow-up video. I have some advice for heavy metal detox. regardless if the level you got exposed to was high or not, you should still go through a heavy metal detox. It's basically a green juice, and gel fiber fast. consume lots of cilantro, kale, and other greens, at least 5 pounds of veggies per day (so you're gonna need a juicer) ..
taking in that much nutrients allows your body to dump the bad crap out.
this is when the lead and mercury heavy metals like to recirculate from your spleen into the small intestine and the colon reabsorbs the heavy metals.
***But when the gut is filled with Gel fibers from plants like Chia seeds, and Aloe.. the heavy metal binds to the gel fiber and is passed out the body. ***
the combination of green juice and gel fiber.
just don't intake processed junk food during that detox.
You can also Research Max Gerson for juicing secrets on healing cancer and other ailments.
As an auto tech/shop guy and ex drug addict.. this detox method has been amazing for me. it's allowed my brain to heal itself.
So you need to pour about 5 more keels assuming that you got that entire 7uG from this one pour to become symptomatic. Great job on the science, folks! This was a fascinating video.
At least, I grew up chomping on lead fishing weights to close them when I was a kid, have shot thousands of rounds of ammunition over the years, worked with lead flashing as a roofer for a while.... I very well could have been a 6 before we started.
We were not significantly worried about the pour so I did not bother getting tested beforehand but it would have been more insightful if I had. Hindsight is always 20/20
Fantastic job Sarah. I hope Steve asked you out for a date. That way we can watch someone help build the boat, that is very intelligent and cutie. LOL Like Joe Brown I've done my share of drinking lead. My first house I had lead pipes supplying water to the house. I'm not as old as Joe but the house had no electric light, it had gas lights in every room. This was not out in the sticks, the property was just outside London, England. How about those subscribers! You seem to be averaging 3000 a week. Yahoooooooo!!!!
It is growing fast! It's so crazy to us, we can't wait to see what happens this summer when we have something that actually looks like a boat!
You found someone to validate your lazy hazardous work habits. Good for you!
I work as an aircraft electronics engineer and did lots and lots of on the job soldering, often without fume extraction. When last tested I was slightly higher than you but told I was perfectly fine,nothing to worry about. Some fruit and veg can have heavy metals in them depending on location. You going to be just fine mate!
Good job guys getting her to speak very good to do. But will they quit no there's always someone wanting to complain but hey let them for each complaint is one more view got to watch to complain. Good job and god bless
It's good that you guys are looking at this in a scientific manner. Also, Sarah is very attractive too!
Bill Hines was a car customizer. He was known as the lead slinger. He worked lead on custom auto bodies for 70 years. Melting it on like solder then grinding,filing,and sanding to shape. All while chomping on a big cigar. His lead levels were crazy high. He also lived to be 94.
Wow! That is some supreme exposure!
Gosh! The world's not going to end because you two used lead! :)
Well I can sleep soundly at night now knowing you have not contaminated all the ground water in New England or ripped a hole in ozone layer or caused global warming. Oh yeah all those things have already been done. Relax and enjoy your boat! I worked all day on my sailboat yesterday and loved it! It is a lot of fun and cathartic from every day life!
The boathouse is my happy place =)
I wasn't the least bit concerned, but all that extra work ya went too, was very interesting and Sara is awesome, what a great video. I gotta ask how much does a soil test cost??? I really enjoy your channel, Ruth @ Salt and Tar suggested you, great tip. Most of all thanks for sharing..
It was around $50
Salt and Tar have sent a bunch of folks our way, hopefully we can thank them in person out on the water some day.
just here to say that battered and fried black locust flowers with some sugar sprinkled on them are awesome. (yes, the flowers are the only part of the tree that isn't toxic. Honey is also delicious)
We have heard that but have never had the opportunity to try them.
I'm glad you did this episode. What about the fumes from melted lead? (Not the dust, the fumes.) I have gotten mixed reports on that. Some say as long as you are outside you're OK. Others say it's dangerous to breath in any amount. Some people use a carbon filter on their respirator, but I've heard people say this won't do anything for lead fumes. Any thoughts?
Damn well spoken
Thanks!
Shame you had to put so much effort in to silencing the comments.......they could have done there own research before venting there ignorance but, I suppose that is the fashion now.
Hopefully the small minded and uninformed wont get all sulky and petulant and resort to spite and vitriol.
I have been working with lead for nearly 40 years and the science hasn't changed one bit.
Love the boat, love the dream, love the passion..........love from the UK
I know nothing about trees so I would be interested to learn why you want and what you will do with Black Locust.
It is incrediably tough and rot resistant. Ridiculously so. There are a few places on the boat where that would be nice to have. Including but not limited to: deadeyes, sampson posts, rub rails, toe rail cap, hatch framing. Anywhere what will not see the light of day and/or will get the daylights beaten out of it like the rub rails.
Interesting side note, lead contamination in drinking water often occurs because water sits inside the pipes for many hours, and when we walk to the sink, and flip on the faucet, lead concentrates will be higher.
I do have a question: Could pewter have been used in lieu of lead?
The thing with lead is it's density and resistance to corrosion, not sure where pewter stands in those regards. I for one have never heard of a pewter keel.
Question, is there anything on Arabella that could be a hand forged Piece? I'm a Novice Blacksmith and I love Sailing, sadly I live in Kansas and have never had the opportunity to learn. I'm about an hour and a half from Lake of the Ozarks and they have Sailing there with a yatch club that has lessons. I will learn to sail eventually and sail the lakes but I wanted to maybe send you something for Arabella made by a Blacksmith. Even if its just a Decorative piece to talk to people about.
Not really other than riveting tools and caulking irons be we already have folks making those for us. If anything else comes up we will let you know. Thanks for the offer!
Just discovered and subscribed to your channel, love it, look forward to the future videos. From the 10 or so videos so far, my only comment is why don't you buy an old forklift (maybe with mud tires) or small crane, literally half of your time in the videos is trying to lift heavy objects, hate to think the days if not weeks wasted on rigging and jacking up objects when a forklift/crane would only take 10 or so minutes. Also its only going to get harder as you build the boat.
It would certainly be handy! The biggest issue is the $$, we just don't have the capitol to afford a machine like that.
Hope that tree you want has acorns or their going to be a name change, anyway it's easy to tell when one has lead poisoning ,they start doing silly things ,like hug trees and beg for free wood. Good luck , I will have a look in the backyard.
Good info! I don't know much about sailboats, but would a concrete keel have been an option? Or is concrete not dense enough maybe?
It is not nearly as dense or as tough, a lead keel is really the gold standard simply because gold would be too expensive even though it would make fabulous ballast!
Concrete is sometimes used, as is steel. There is even stories that Sir Francis Drake used gold for ballast on The Golden Hind. It may just be a dig at the Spanish.
Salt and Tar is using a concrete keel. I'm curious as to how well it will hold up over time.
Trouble with concrete is it's not as dense, so you need more of it, and you wind up with the center of mass higher up the hull. Boats sail best with deep ballast. Steel is bad because it rusts. You can seal it...but that's always temporary. Eventually the seawater finds a way in...then the iron swells as it rusts.
C'mon what's a few more bucks!
Huzza, huzza, huzza! The RUclipsUniversity suddenly was upped 10-fold. Great content, great lecture, great performance, great visual (the beauty is in the women). So huzza (old sailors term for hurrah) to Sarah and her crew.
However, if this exercise should have been really interesting, soil samples should have been taken from outside the pour, but within the old barn perimeter + at random in the area outside. Also, blood samples from before the pour and from more ppl might have upped the science level a notch (just a thought).
Thanks! At over $50 a test it adds up fast! We also were not anticipating the rabid outrage over the pour so we did not think to do tests ahead of time.
Wow, that will shut them up.
There was someone listing black locust on the providence craigslist a couple months ago. He was taking down a stand of it and offering it for firewood.
That's a bit of a haul from here but we may end up going out that way to get it. There seems to be a lot of it out east.
Acorn To Arabella I believe they were willing to deliver for a fee.
Acorn To Arabella Oh, and since it makes the second best firewood in New England, you might just call some firewood guys for leads.
So i'm curious. Did you find your Black Locust?
I used to be a tree surgeon and climber. Beware. Black Locusts have huge thorns and the wood is amazingly hard. Feels like your cutting through concrete when using a chain saw on it.
We did! Some from Cape Cod and some from North/Central Connecticut.
The massive decrease in violent crime in the US in the 1990s can almost entirely be attributed to the removal of lead from gasoline (some 20 years prior).
Bravo!!! Those that posted all in a huff over "lead contamination" and save the world from lead should volunteer to help rebate lead in old homes for those that afford to pay to get it removed. Less talking more helping???
This is your "lot less troubles with lead" instead of using iron rods?
Thanks for the interesting videos.
A soil sample from the most remote, never-built-upon corner of your land would have provided a basis for comparison. Maybe neither your pour nor the barn raised natural levels much above the natural level, but that's needless precision for your purposes.
Thanks again.
Thanks!
If money was less of a concern we would have sent in a mountain of samples for comparison but at about $50 a test it adds up fast!
I worked in stained glass for a number of years, we worked directly with lead pieces, so lead was an issue we had to be trained on and take precautions for. The primary route is ingestion, most often by transference from hands to mouth or via some intermediary... diligent handwashing is the key to avoiding that; avoiding touching your face while working with it. never eat or drink anything while working in /around lead and thoroughly scrub your hands down after working with lead... (depending on the nature of the work, changing clothes & showering may be recommended....)
inhalation is the next route, but that requires super fine particulates and dust and / or vapours...as long as you're not breathing the vapour from molten lead, this is hard to come into contact with.....smoking should be avoided around lead for the same reason as above....
absorbtion through the skin is the lowest route. your skin is largely impermeable to it, but it can leach through over time. Again, handwashing after handling is reccomended. Lead can be safely handled with bare hands, but standard work gloves are recommended in case you have any skin abrasions or cuts and it IS a heavy material, so gloves help prevent injury.....
In the glass shop, we wore heavyduty surgical grade gloves to prevent lead build up from rubbing off on our hands...and there was no eating of drinking in/around where we were assembling leaded panels.. (it was a general rule that only "closed" containers were permitted in the workshop in any case....)
I did stained glass for over a decade myself and agree with your comments. In the time I worked there, I was very diligent about hand washing. I also wore a respirator when soldering. I was tested for lead early on in my employment and then again years later. My levels were actually lower at the second test, after years of handling lead. I'm guessing lead isn't the bogeyman it's made out to be...
Good shop habits solve a LOT of hazard issues.. :)
it's a bogeyman for sure, though it's not nearly what it's hyped out to be...
it is, in that if you DO get enough of it into you, it's a serious problem getting rid of it....and the routes into your system can be insidiously 'normal" so you do it without realizing it. (one study i read, discussed "incidental ingestion"....getting it on your hands, then picking up a sandwich or cookie....that sort of thing....)
however, it a VERY managable risk, if you're trained about it, understand what precautions to take, and are diligent in your shop habits. You can avoid virtually all the hazard with very little effort...
There's a lot of hype. I think most of it comes from the fears of contaminated drinking water...
What a bunch of melowdermacts. Those people need to get a life. It's good theo you covered it so well for the ones who don't have a clue to hard work or what goes on in the world.
5 yrs ago I had my blood tested for heavy metals, and lead was 37u; when I was young they put lead in gasoline. Also used to shoot smallbore rifle in an indoor range. (arsenic was the concern. a partner had high arsenic levels). So the irony is, I'm sensitive to Black Locust, and it's the bark, especially decaying bark. We had some (14" BH) I took down for light, and I made a deck out of the forks, left the bark on for the cats. Some got sawn into boards with a Ooga, and the rest became firewood. It was when I was splitting the firewood and getting into decayed bark I got contact dermatitis -yow! I was going to work with one of the boards the other day, but chickened out.
Tip: don't touch your eyes with your hands when handling the bark. Wash your hands first.
Thanks for mentioning the hand-washing re. Blk.Locust! I just left a long comment above re. the dangers from sawdust inhalation. I didn't really remember to mention that once you're sensitized to the stuff, it's not just breathing it, but ANY form of contact can set you off.
I have heard of some folks developing reactions to it but I have also heard that about oak, cedar, latex gloves... I have not heard about it being this bad though. Will have to do some looking into this. We have met numerous people who work with the stuff and have never had a issue.
.... learned to wash my hands VERY THOROUGHLY before going to the bathroom especially after playing in woods filled with Poison Ivy, Oak & Sumac!!!
Seems to be many different opinions, a few boat building sites recommend adding antimony to the keel. Without antimony, the lead will be weak and likely to creep - or in the case of a keel probably likely to become a longer keel and eventually fracture and fall off.
Plus there's also a trend to ditch lead for foam - “I got rid of seven tons of lead in my keel, now replaced with foam, and hey, big surprise, my boat sails way faster, especially off the wind,”
The lead is important in our vessel to keep her upright. Foam would not work at all! haha
Yes my bad, tender and cranky so lead is a must - Chapter 11 explains this
i have watched 46 of yall video so far. are they going to continue to the launch it days there are only 75
We are still mid build. Should be planking this summer. We will definitely be continuing until launch and there should be weekly videos from now until then.
Amazing with the wealth of knowledge avilable that so many are misinformed , get infromated and act on Real problems ?
There are indeed much bigger worries and threats to humanities health then our 1 time keel pour.
