Pouring Lead into the Keels
HTML-код
- Опубликовано: 25 янв 2016
- Casting aluminum and bronze is fun, but it hardly compares to pouring a one thousand pound river of molten lead five feet down in the keels. We have done three pours now and have the major bugs worked out. Still at least seventeen more pours to go. It make get old, not yet.

WARNING: Lead is extremely be hazardous to your heath. Most people don't know how or why, but somebody important who had worked for the EPA, told them that was the case and assured them it had destroyed their uncle's brain, turned his blood yellow and cause him to eat babies. Just looking at molten lead without a full class one hazmat suit will cause you brain damage. Consider yourself warned. It is now your duty to spread the fear to every neurotic recess of the internet.
Rational Precautions for Working with Lead
-- It most dangerous to the developing brain, so women who may become pregnant and children are the most susceptible.
-- Transfer is commonly through dust ingestion. So have no food or drink. And avoid cutting or grinding or other activity that will create dust.
-- Do not smoke as it will vaporize any dust and lead vapor will easy be absorbed in the lungs.
-- Keep the molten lead below 900F/482C. It melts just over 600F/315C so just turn off the heat once the last ingot is melted.
-- Control the contaminated area so it does not spread to food, water or others.
-- When done, remove your work cloths and bag them.
-- Take a shower before you do anything else in the house.
-- Wash your work clothes with no other items.

Best channel on RUclips.
I'm addicted to watching SV Seekers. The second I get a notification on my phone of a new episode, I grab a coffee and watch. Thanks
Q:What am I doing wrong here?
A: Your learning.
Again, what a fantastic outlook on life you have!
"You know the answer" This kind of mentorship is invaluable. A little transitive confidence goes a long way.
I like that 99% conversation.
Now you got everyone, wanting to go out and buy a ton of lead, just to watch it run. Great job.
+Kent Dutrieux I'm glad I have all I need. :)
I think it's hilarious you include the video of you arguing with the guys, good comedic relief after learning a thing or two!
+Christopher Miller I keep my soap box close.
+aserta Fuck No! I can't afford one of those.
+aserta He has a swear boat...
This should have its own TV series, loads better than the crap that's on here in the UK! Great Job
I started watching your channel yesterday and have caught up to the present today. This is an addictive channel to watch. I love the fact that your not afraid to build something like this, not to mention in your front yard. I live in california where you would be arrested for even talking about doing this kind of build.
It sounds like you have all the lead you need although do you have all the help you need. It would be a good vacation for some to help you with this. Good luck and thanks for video taping this for us to watch.
+Jon Haslam Land of the Free, right?
Way to go! Awesome seeing the process optimized. And one thing I love about casting metal: you just melt down yesterdays mistakes and start over. Not that walk of shame to the woodshop buying the same stuff all over again :-)
you cant keep a good man down. i watched your first attempt with my heart in my mouth. that was a good warts and all vid. but just like i knew you would, youve come back and it looks like you havent missed a beat great vid doug all the best
SV Seeker, to the gentleman who suggested filling the keel with blocks of lead then filling the void. Even if you could (I agree that you cannot), they cold lead would be such an effective heat sink, you would still have voids even filling it to the top. The more surface area you pour to, the quicker it will cool. I do some bullet casting and trust me, a bullet mold that isn't properly heated just will not fill right. By the way, Ive been watching you from the beginning and really enjoy the videos.
I just stumbled upon this and I must say, I really like how you edit this video and I assume your others. Well done man, very enjoyable to watch.
You following now?
"O that looks good". Looks like a fucking alien murder scene.
Great channel! Just found you and subscribed. Keep up the great work with the videos! Very informative and straight forward. Cheers!
Hard to believe I have been watchin your channel this long ...THANKYOU
Great result Doug - looks like you have nailed that pour now. Just another 17 to go -- phew!
Another great episode.
Congratulations on the successful pour Doug! Good job and very enjoyable video as always! :)
My father built a 42' motor-sailer and we had a good time pouring the lead for the keel. We melted 1 1/2 tons at a time in an old cast iron bath tub and ran the lead into a wood form. We poured a total of 5 tons. We used a coal fire for heat and the exhaust of a vacuum cleaner for an air blast to make the fire hotter.
+enginebill Well done.
its great to see the lead is pouring good now almost another tick off the list douge and soon the rudder will be all done and mounted its great to watch as seeker comes to life bit by bit and all the great friends you have made along the way lots of extra knowledge from different people helping and even commenting there ideas .looking forward to the next installment of the seeker project lol all the best big pete
Love the casting videos, I learn something every time you upload a video. Very inspiring to see your project develop.
This build video just gets better and better with each episode.
Nice Job Seeker!!
That was really cool stuff. Loved it and it sure looks like all of you nailed it down pat.
Well, you've got the lead pour worked out and seem to be satisfied with it. Good job
Thank you for the video, it's real nice to see them.
Awesome video. Latecomer to this project but I've enjoyed it immensely.
Looking forward to when you guys launch her and get out on the open waters!
Hell ya! Been waiting to see how you'd accomplish this since the day Tyler told me about your project, I like your keep it simple approach
Great work as ever... on the filming as well as the boat
"Do you know what 99% is?"
"About two inches from the top."
God, I love salt-of-the-earth engineering.
Wow! You are doing a big project! Inspirational!
Steel expansion happens on the side heated because the molecules spread apart on the hot side first. Great job on everything. Thank you for the knowledge.
We'll there is more to it than that, like the shape of it, because it flexed inward.
@@SVSeeker Yes, but it flexed inward the side which saw the heat first. Think about it. Mmm?
I’m, I love what your doing. Very ambitious.
dammit these videos are few and far between :). I love your build. i've seen and re-seen everyone of them. Keep up the good work. hopefully i will be able to come lend a hand one weekend.
Very cool video. I hope to see more in the future.
It’s crazy that this video took place 6 years ago. I feel like it was just yesterday.
Yay a new video!
remindes me of hunchback of Notre Dame! I love fabricating everything you do. Custom work! videos are like night at the movies! sprit is always with you. just saying mercy! mercy! from Phoenix, Az. Happy trails! Jim.
Wow, I didn't think the steel would move at all. Boy was I wrong on that subject. Way to go Doug.
well done, excellent work.
Thanks for the update good video as usual
*high five* - glad the pour got all figured out!
Can't wait to see those dragons lit up.
I've done plenty of low-temp casting, and the bar/shot suggestion won't work because the molten lead would lose heat to the bars, even more so with the shot due to higher surface area - it'd freeze out and choke off before it flowed in. Early on I tried to fix "oopses" by re-pouring, reheating the mold and re-pouring, etc. - I always wound up with two parts in one mold, it never fused back together.
You could toss some shot in to force a quicker freeze against critical structure, but I doubt you could get down there and pile the shot just right - might as well just have someone under the boat with a hose on that particular spot to keep it cool and avoid warping.
Really cool to see it go well for you this time. I know small pours that go wrong can be frustrating, but a big pour like that... that's a hell of a lot of propane and hard work to re-do!
Great stuff, Guys.
I bet with multiple pours a day the inside of the holds are nice and toasty..The pouring over the cavities length wise is a stunning victory, Looking good Seeker and Crew !!
nice job doug,winter is a good time to do the lead with all the heat from the melting of the lead.At this point do you have any idea when you might finish?
+shawn burnett (tailermade) Hope to finish with the lead by May. That's about as far out as I ever plan. :)
We have been pouring lead keels for 55 yrs the first thing we deal with is shrinkage the best way to do that would be to drop some ballast lead in first spread it all around then pour ur molted lead as quick as posable into the cavity it will melt quite a bit of the ballast that's in the ingots u dropped in keep using that system to u get to the job is completed
cool glad yu got the pouring thing figured out,.your my closest yu tuber I may come for a visit one of these days,fair winds an safe travels,,,paul
Really cool man. Liked and subscribed
definitely the coolest video I've seen in awhile
Many thanks for the reply great videos. Wish I was stateside to come help you guys
hello but if you fill it with sand and cement ? it's the same?
+Dlc. hp No. Lead is over 600 pounds per cubic foot. Concrete is only about 150.
Just wondering if the water would shoot to the top of the lead thus not being trapped?
I hope you filmed all the other pours! Because... y'know... We'd like to watch them.
Might sound a tad silly, but i got a tad excited watching that lead poor. That was so cool to see it flow, made me wonder if any large ship builders would see this and I'd love to hear them comment on the small guy building at home, such a great project.
+SupaLexy (SupaNautica & MotoLexy)
Large ships use concrete.
Cool, the methods may be different but still good to see the small guy building such a large boat at home.
This is great. You guys are hilarious. I cast from 10 molds different loads all for 12ga. This is awesomeness. Subscribed..
That was fun to watch. Thanks!
Not sure if I missed it at some point..... what was in the keel before?... what would the shipyard have used if not lead?.... and what effects of displacement does the lead do for weight of the ship?thanks for your time and I loved the video....
+everwharesismine Nothing was in the keel. This is new construction, not a refit. And it's hard to beat lead but iron ingots and steel shot in epoxy would be my next preference. If it's a motor boat the ballast is not critical so even concrete would do, but I would not want it rested against the hull as it holds too much water.
The largest keel pour on youtube! Believe me Ive looked! Glad it worked out
bringing back memories of my Navy days..... love the vocal camaraderie....
I'll never grumble about the "hassle" of casting lead bullets again. I've got it easy.
Nicely done on the upgraded pot, that old melting tank was ok for making ingots back in the day but just not up to the task for this. flow rate is sooo much better now that the duct is just getting in the way. :)
is the lead to add weight to the boat, and give it balance?
+NosillaWilla Exactly. It counter balances the sail.
Where did you get all that lead?
Great job ! Was very satisfying to see that river of lead pooring down ! I really enjoy your videos ! My only complaint is : Since i discovered you channel, i've look at all your videos, spent a few evening on them... but now i'm catching up and i have to wait for the next ones :) Oh well, since you still have years of work ahead, it might give me a chance to come down from canada someday and visit you guys ! Keep up the good work !
looking GOOD Lewis!
+Larry Wills Feeling good Billy Ray.
Task: Get lead into the keel; Method: Anyway that works; Outcome: Success, WooHoo!!
As long as we can agree that lead is completely harmless, we're all fine and dandy
OMG - 9:07 - "That looks like a lot more lead than we had last time......." "......................" "..... HEH!" - So awkward haha I replayed like 5 times and died laughing haha
It is looking great! Do you plan to cap the finished keels with steel?
+Robert Dietz Yes, a steel cap.
I like all your videos 👌.. great work.... ❤️ from India
Can I suggest several things from my experience?
1) Get 2-4 big fans going in there - even if you're not heating it up to boiling, you're getting at least a little fumes. Down inside the boat that's not going to be good for you with the volumes and time you're dealing with. Lead poisoning is pretty brutal with long term effects.
2) Preheat your lead while adding it to the pot - someone in the video mentioned the lead was wetter than before. A steam explosion with that much lead in a confined space will be pretty devastating.
3) I suspect you're already doing this - but a circular shield around the burners leading up to the pot with an air gap around the pot will focus the heat and decrease your propane usage and heat times.
+H Wal. 1) Heat rises already. 2) Explosion is way over the top for describing steam coming out of lead. 3) Did you watch the video or did you just read the title?
+SV Seeker Look, if you want to ignore suggestions all the power to you. They were made with the aim of helping you out. Lead fumes don't rise, they behave like a heavier than air gas, though they aren't. Explosions happen when water is trapped in unmelted lead. Since you mention 17 more pours and significant quantities of lead being poured each time, a deep pot, and apparently little concern for it, there's a decent chance you may actually experience an explosion. If you're unconcerned with steam explosions take a look at thermal and casting explosions - they're no joke and one of your main concerns when casting any metal. Finally, you wrapped the crucible with kaowool, which eliminates any chance of heating using the exhaust gasses by insulating the sides of the crucible against it. If you were protecting against cooling after heating the wool would help, or inside an oven. As it stands it does maintain heat, but slows heating itself. Anyways, maybe that'll help you from getting lead poisoning or burns.
+H Wal. Look what tiny tiny bit of vapors there might be will be carried out with the massive plume of heat off that burner, and fresh air is pouring down both companion ways. And steam bubbles. We show it in the video. And your totally wrong about the insulation too. It cut the heat lost through sides and cut the melt time in half and the fuel consumption by 20%. And your fears of lead poising are totally unfounded. Read the description and the linked article in it. And please, before you go spreading fear, do some research and make sure it's a real danger. If you want to stand on the street and warn people to wear their seat belts, the science will back you up. Claiming we are in danger of lead poisoning given the precautions we have taken is simply baseless.
Im curious, why would you want to pour lead into the keel, aside from lowering the center of mass which I do understand, are there any other reasons to pour lead?
+2009dudeman Nope. That's the reason.
Does the lead contract much in there once it's cooled? Good to see you got on better this time
+deeryme Yeah. All metal will contracts about 2% from molten to solid.
did you heat up the keel before pouring the lead to allow it to pour into all the gaps so it would not cool down to quickly// and how did avoid air pockets/ even distribution throughout the keel ??????????
james guias its just for weight.
well looks like you have it figured out, nice job.
Hi, I just happen to come across this video. Looks like you are building a big boat. How thick is the hull?
+bob5466 1/4"
That was a pretty intense job. It's interesting how much it pulls away from the steel when it starts too cool.
Is Jack planning on coming out when the boat is in service? He sure does help a lot.
+dus “dustoin1386” toin Absolutely. That's why we call them crew.
Rough old boys having fun! Wish I was there with ya!
A great vid ... Keep at it..
I wonder can the gap between the lead & steel cause problems? im thinking condensation accumilation etc.. maybe the external water preassure will squeeze the keel enough and take care of it? just a thought that came to mind.
great video again Doug. Im still worried about the lead fumes though.
+Kopsu No worries. Water pressure is only about 1/2 psi per foot of depth. So 6 ft is only 3 psi. Now when the boat sinks into Challenger Deep that will become 16,000 psi and a real problem. ....but other bad things happened first. :)
I can only imagine how hot it would get inside the boat trying to melt 1000 lbs of lead in August. It might get old, But me thinks it is better to do the lead during the cold weather. All that molten lead at one time flowing out of the pot is amazing!
+tbirdracefan Hell Yes! We do plan some things.
Seems to have worked great!
I had an idea about your distortion problem. Do you think spraying the outside of the keels with water during the pour would dissipate enough heat to cut down on the buckling? I like your idea of dropping bricks of lead in first. that will cool things down quickly and likely be enough. it would be sad to have a keel side permanently convex.
What's the deal with lead and thermal expansion. Did the boat bend out or did the lead pull in?
+wouldntyaliktono The steel bent inward when we heated it up. And then the lead solidified. Then the steel cooled and went back to it's original shape.
+Sv seeker, forgive me asking, but aren't you guys worried about the fumes given off the lead? Really dangerous I thought the fumes were?
+jbss7382 See the description.
Good Job Doug, lead is interesting. Lead can be taken out of the earth and put to work. Weapons, was the first order of business. My Trade was named after Lead. THx for your videos.
I know there is talk of rust in the keels and I had a similar non salt water related project that we poured oil into. The oil would eventually work its way around the lead and keel hull. Not sure if you could still pour the coal tar in after though
+Dans L'eau Yeah. Oil, diesel, epoxy, tar, .....
I'm probably asking a question that has already been answered. How are you going to move the boat to water when you get it built?
+kingmike40 Truck it. ruclips.net/video/YZyychQJq8o/видео.html
is there a way to melt lead, chemically?
Just wondering why you would work around molten lead without respirators? Just asking for trouble down the road with lead poisoning.
Because if you read up on what the dangers are you'll see they are easily avoided and respirators are not really necessary.
Doug, when you plan to transport the Seeker by tractor/trailer. have you consider road weight with the lead in the keels, plus dry weight of the boat and the truck/trailer combination. Most states require permitting for large loads. With the lead, are you pushing road weight limits?
+Bruce Watson Not an issue. Permits are easy.
So all of those lead cavities get sealed up completely air-tight right? curious because it's just raw steel down there and after the lead cools i imagine theres a small gap all around the big pieces that could pose problems if moisture gets in.
New subscriber coming here from Jalopnik, love the channel! would love to come help with my engineering buds when the college semester is over this summer, really neat project.
+Braddock McDonald Yes, exactly. A plate of steel gets welding on top of the lead. And welcome.
Had to review the keel construction. It looks like you are able to fill the wing sections mostly in one pour. Guess it turned out to be simpler than it looked at first.
Doug, forgive me if I've missed something but what was the reason for having water in the molten lead pot when you poured? Was it to get the lead to flow out better?
+Charles Phillips There is not water in the pot. That big piece he put in had air pockets and likely some moisture, but any water quickly converts to steam.
Oh, I see. I heard you make that comment about water and then the pour had liquid and chunks and I thought the liquid was water. Time to get my eyes checked.
Great video! Where the heck did you get 10,000 LBS of lead from?
ruclips.net/video/5Ljldtu-u-s/видео.html
Why did you pour lead into those openings?
a few gallon of polyester resin on top would seal the job off nicely, and stop any water ingress.
+spinaway I've considered that, but I think something like coal tar epoxy with more flex would survive better without pulling away from the steel.
We did this with a fishing boat we built, the resin is thin enough to fill all the gaps, its fifteen years since it was poured and still as good as the day we did it, just a thought, great project by the way dug, greetings from England.
+spinaway You got resin thin enough to flow down the crack between steel and lead?
+SV Seeker yeh it was very thin it flowed right to the bottom of the bilges, formed a brilliant seal, if you buy a gallon and make a mock up you will see how well it flows.
+spinaway Better to have big gaps than small ones. Capillary action will get you. Thin layers of things close together draw in and hold moisture. Resin tends to flex at a different rate than metal and flake off. As it does so, it will make a blister of moisture you can't inspect underneath. Also it tends to degrade into little chips which bugger up bilge pumps.
Are you doing this to create extra ballest or for some other reason?
+Jonathan Cook Yes, Ballast
Any worry about the gaps left after the lead cools? Could that rust and eat from the inside out?
+Paul Myers We are going to entomb it under a plate of steel so it suffocates.
love the ship bro.. keep up the good work!! I'm a huge fan! I'm in Nashville and as soon as I can count me in for nonstop welding..lol.. I restore classic cars for a living so hand me a mig and its on HAHA.
