Mast Step and Alignment - Episode 152 - Acorn to Arabella: Journey of a Wooden Boat
HTML-код
- Опубликовано: 2 окт 2024
- With wrapping up the bronze floors comes working on the mast step. This wild looking piece is built up out of live oak and black locust and looks more like a sculpture than a structural element in the boat!
We also check alignment on Arabella to see if everything is still where it should be. Granted, we should have checked this before installing the knees but on our small routine checks, nothing seemed to have moved.
And finally, we'll be getting started on spars soon!

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.

RUclips notifications: I noticed, several months ago, that ALL of my "notifications" were changed to "personalized" which means that you don't really get any notifications. This happened on many of the channels that I am subscribed to so I went through all 100 + channels and made sure that they were all reset to "All." Hope this helps the subscriber base. Thanks, Stephen, Alix and Ben, for this wonderful channel. You keep reminding me of my older brother, GOD Bless his soul and may he rest in peace, as he had been in the U.S. Navy and loved sailing. He would have appreciated your channel. Much love to all and my sincerest thanks and appreciation.
I just use the "subscriptions" tab on RUclips, which lists only my subscriptions, in pretty much reverse chronological order. I consider real time notifications intrusive. But this way I don't miss anything if I check in once a day or so.
Man, it seems like it was just yesterday I watched you guys pouring lead in a wooden keel mold. Absolutely awesome work guys! Im so glad I have been able to follow your work!
Thanks 👍
I gave up on RUclips notifications, and just check every Friday at 7am because y'all are punctual.
The progress is speeding up! I got a genuine thrill of excitement when Alex said he is starting work on the rigging and Stephen is starting work on the interior. I remember when it was just a chunk of lead in the ground and even before. Yeh, I been here since the beginning. So happy for all you have accomplished and all that is to come. Cheers!
Who need notifications, I'm waiting from Friday morning until this comes up.
Me in a nutshell, I just check my subs every morning

I absolutely love the quality of the videos now, with Ben doing the editing and both Steve and Alex doing a mix of filming and wood working👍👍👍 oh and Ben's music is a really good fit for the project. I'm honestly just blown away how awesome the channel has become since the start 👍👍❤ well done team
Thanks, Matt!
Waiting for lunch as always; cold here...cheers rr Normandy, Fra.
"Hey, quiet on the set"
I'd never even thought about that. Of course that's a disruption to your work...
Put some radius where you’ve cut the floors down to prevent a cracking propagation
For sure.....I was watching that and was cringing. Looks like a perfect spot for a crack to form.
New music is great, and love the new intro best one yet. Though I do expect to see "Special guest, Norm Abram" :D
Have your logo made into a burning brand like winery and then burn it on pieces of wood and they can buy it I think that would be cool especially if they’re in a shape of your hull or something
Second this!
They could only sell them in the US. Shipping wood that has not been sealed tends to upset customs officials. You then need a fumigation certificate.
@@steampunkskunk3638 you could get a fan (ME!!!) to build and send them. sent over earnings
the wood would need to be sealed to send to Australia, we have the toughest quarantine rules in the world.

Steve, a question I've had for a long time now: When planing over an edge, as you do with the mast step there (9:45), aren't you worried about "tearout" as the plane goes over the edge?
I am finally caught up with the project of
yours. I pretty much binge watched the whole thing. Seeing you guys work so
hard on the boat really sparked the love for wooden boats in me, thank you for
doing that. Watching the whole process gave me a feeling that I now actually
know something about boats, you guys really explain everything very good and
detailed. It’s also awesome to see two friends with totally different skillsets
come together and tackle such a big project and do it with flying colours. You guys
are really awesome.
You've made our day.
That was a really smart move! Everyone knows your woodstove will get MUCH better reception with the bronze rabbit ears! lol
Are you guys going to use hammocks for berthing
Best way to finish off a hard week. Hope that you guys are doing well.
Kudos for the filming and the editing! Looking forward to my Arabella fix every Friday!
It's surprisingly visible how much Alix enjoys woodworking: there's a certain way someone looks at something where they're applying their expertise to something they enjoy. I'm glad he's enjoying it!
I find the mast step curious. I know "Atkin", he keeps things very basic. Did you modify from the Plans?
I know you guy do a lot of testing and what not, however (as a metal fabricator with over40 years experience) can I make a suggestion in order to save some possible serious grief that will be coming down the road. When cutting the webbing on your bronze floors you may want to take great care in putting in radius corners internally and to some extent polishing (not a high polish by any means) but you do not want any sort of grind marks going sideways across the end of those plates that will absolutely cause a stress riser and eventually crack those floors in the corners where you cut them. Simply a suggestion nothing more.
I also agree with Hansa. Those cuts of bronze introduce a potential point of failure for serious crack. This should be fix. As an aircraft builder, with time and multistress vibration, with learn it the hard way.
@@christiantremblay Christian I too was a A&P many years ago before I got into racing (many A&P guys get into some form of racing) it all carries over very well into race cars, after all fast cars are nothing more than aero packages that are upside down!
@@Mtlmshr I love aircraft, sailboat, RV, motorcycle, or anything can move with an engine or with other forces. I wish to go on other planet !. :-)
Limited mast step clearance has sunk boats?
I dont think you are novices anymore. Skilled apprentices with a thirst for knowledge would be closer.
great idea on maybe widening the effective sole by a plank or two up the frames. I just did 1500 miles from RI to USVI basically 10 days at 15% heel (yup easterlies the whole way) and anything "level" would have been appreciated. Especially for standing/cooking in the galley, cool idea. 1/8" width variation amidships? Amazing.
Gotta love camber in a deck for that, too. Just a tad more level for walking on the windward side when heeling. Of course, it's mostly for shedding water, but a good camber set in a deck makes it safer to go forward. Congrats on what sounds like a super speedy passage! Catamaran?!
@@AcornToArabella yuck catamaran. no, Valiant 42! cutter double ender cool old school look in fiberglass and fast
I can identify with completing a a milestone on a project. Nice work guys! 👍👍
Guys mounting your mast step directly on top of your bronze floors is going to apply a great deal of fore and aft pressure on the floors that they were not designed to take. The simple expedience of adding oval blocks as packers to the bottom of the mast step and pinning through into the keel would eliminate the effects of fore aft strains and continue to allow bilge water to flow in the correct direction. As an after thought you could weld bronze plate into the floors notches in sections or as one long piece connecting all four floors and drill and screw through into the mast step, this would resist fore and aft side to side and rotational forces whilst at the same time spread any loading more evenly through that section of the boat.
I think the reason the step interface block is knotched is so that no downward forces are transferred into the bronze floors, but the vertical forces are widely distributed into the keel. I'm not sure yet how the interface block is being fastened to the keel or how the mast will be captured into the interface block.
@@boooshes Mast step only slotted for central two floors, and appears to be in the position Steve intends it to be, without packing all forces no matter the direction will be transferring directly through the floors.
Curious about fire suppression plan for the boat house. I'd hope there was something automatic to deal with any disasters.
RUclips notifications are, and always have been, utter crap. Don't rely on them, just use the "Subscriptions" page and scroll down it, adding videos you want to watch to the "Watch Later" list, until you reach the videos you have already watched.
Hi Guys, thanks for the video update, great idea regarding the newsletter I have noticed that some , not all, of the notifications have been bit late but I have been receiving them looking forward to next friday, see ya!!
I noticed the boat moving a couple of weeks ago while you were working on it. It might be time to reinforce or add to the supports. She's getting a bit big for the cradle. :)
You have been working on this boat for ever.
I have enjoyed watching you.
Will we now find you on Google Earth ?
Akeera sounded like he sorted out the outside issue! Great job guys best regards from England see you soon
Hi guys, like your videos. Did you have any issues with the County on the shed structure where you build the boat? I see that Leo (TALLY HO project) has big issues with his project because of the County demands
We've had to change the shed (see previous videos) depending on what building inspectors have wanted. Massachusetts local authority is set up a little differently, and also, we're on zoned agricultural and forestry land-and this is a forestry project.

Hi guys. I have not experienced a notification problem. I get notifications just like I always. If experiencing a problem, maybe they should check their system. Best regards.
I am worried about the way you put the mast step on the floors. You basically put a large block of wood on four knives. If your floors are 1/2" thick and the mast step is 10" wide, the total surface of wood resting on those four bronze floors is 20 sq inch. The maximum safe pressure on wood "in general" is 60 psi, so you can safely put a 1200 lbs load on it, which is probably the weight of the mast and rigging. If you put load from tensioning the shrouds and heeling the boat in a fresh wind plus vertical acceleration in waves your mast step will gently lower itself on the keel. Not a good plan.
I would say to reconsider this and come with a safe plan. Frank Mulder, Amsterdam.
I hope you know and realize what a fantastic project you are doing. You are gaining so many skills, technics, and knowledge. As you mentioned today. You didn't know what you didn't know until you come to that step. What a great experience to have at your age. Keep on keeping on.
Dummied up? I've been watching your progress since ep 1 and nothing that ya'll have done thus far strikes me as "dummy" work. In the manufacturing world, what you have done with the cabin is more correctly identified as a "mock up."
For a sec there it sounded like you were describing a delicate operation. Should'a known better.
Love you guys! I just turned fifty! 😑
Hi, really enjoy following progress on Arabella each Saturday morning here in NZ - great job. I’m a little concerned that the step block appears to be being supported solely by the 4x ½" edges of the bronze floor uprights, rather than using the full underside of the step block resting on the keel timber. This doesn’t seem to me to be a very effective way to support and transfer the weight from the mast into what is effectively the strongest part of the hull. Or is the plan to eventually remove timber on the underside of the step block (around where the wings of the bronze floors attach to the keel) to allow it to then sit flush on the keel over the wings of the bronze floor?
Why is attaching the mast to a thin plank and 5 floors+frames stronger than attaching it to a GIANT timber and ALL the floors+frames?
I broke it down in a comment on the last video but I'm fairly certain the keel timber, with the frames being wedge-shaped, attached to all the frames, floors, and even planks.. would be a much more sturdy attachment than a smaller hunk of wood that's only attached to half-a-dozen bronze floors.
Steve's reasoning in the last video was that the keel is already under a lot of strain from everything else and that it wants to pull out the bottom.. But the keel is not only lined with a few *massive* planks tying it into the frames, but it's got like 30+ bronze V-shaped wedges on it that would have to spread all the frames, planks and everything else apart before it could push out the bottom of the boat.
Man, I get nervous watching you chisel towards yourself!
Edit: the other thing to check dimensionally is *diagonal symmetry.* Measure from centerline to a pair of points X" aft of that. Should be the same distance both sides.
What about filling that large check in the Black Locust with epoxy? Also, are you planning on rounding over the right angles on the bronze tabs you just cut? Seems like it would relieve the possibility of stress fractures, plus just look cleaner and be safer. The project is looking great!
You guys are not craftsmen but artist. All i can say is: F@CK, IT'S BEAUTIFUL!!!
@1:44....why would you encounter a "strong downward force" over and above the normal mast loading from the weight of the sail and ropes and fitments? Wind gusts might be the assumption, but would that have a downward vector component?
I really enjoy following this work.
I cannot make myself like the oval shape of the forward cabin portholes.
Do you guys ever contact Leo of Tally Ho project and compare notes or progress? And where in the boat have you planned Davey Jone's Locker?
Hi guys, not sure if anyone has asked this question before, but how do you intend to move Arabella when she is finished, and how far are you from the nearest water?, or are you going to wait for the ice caps to melt and just sail her out of there! lol. Stay safe guys and best wishes from "Over the Pond" Cheers... Les.
For centerline and checking get a low price laser. For a few hundred, and along with using plumb bobs you’ll be able to use it even with later cabinet work. They get way more useful as you get the hang of using them and the many ways it helps without strings in the way.
I was looking at all the bolt ends sticking up like 2-3 inches. If you fall on these, guess boat building will be over. And could be forever. Is there nothing to be done here for safety?
You could gain some floor space by channel cutting the outboard side (closest side to the hull), of the floor planks to slip past the ribbing, and then angle cut the outboard side (closest to the hull), of the flooring to provide some space for ventilation and drainage into the bilge. You could gain as much as 4 to 6-inches of floor space on each side of the boat with this process.
Wooden boats will sooner or later be canceled I'm sure because of some '-ism' that offends 1 person, so I think it's smart to have an alternative network not tied to the morons running youtube social justice compliance.
Hey it looks like RUclips takes away the thumbs up that I put on on your video and makes it like I’ve never watched it so I go back to the same video and I can watch it again but it’s like they’re not giving you credit for me watching it that’s what it looks like on my side, and that’s on all the channels that I’m watching right now for some reason
Purchase? Are you high? Do an auction for the big ticket items man - you'll make 1K on that samson post!
Out of morbid curiousity. Why cut the bronze floors as deep as you did? I get needing to nestle it in there but seems like they (even the one) is significly weakers. Also are you going to weld on some tabs or brackets to better hold the mast block, and bolt it down?
I am puzzled as to why you mounted the mast step to the top of the bronze floors via slots in the wood as well as why you removed metal from the floors to provide clearance to the mast step when you could have put a rebate into the wood. This configuration appears to be weak to forward and aft loading and will cause additional fatigue stress to be focused on your welded joints. You both are really good at research and I am sure you have a reason for doing this and already have a solution in mind to mitigate this issue. Thanks for sharing.
Would it not be better practice for the mast step to bear directly on the keel rather than upon the few floors, and just use the floors to locate it fore and aft? Distribution of the load seems more prudent than concentrating it on the few floors.??????
Are you going to put some more bronze strip on top of those vertical pieces? The pressure exerted in those thin sections pressing against the oak will dig in and cut into the step eventually.
1:09 you completely ruined the strength of that bronze wishbone, cutting at that spot creates a bending moment over it.
I remember when you guys started (binger here) Alix was more likely to have a tree fall on him than put a nail in a board.
Was waiting for the video 😀
Guys she is looking great.....question, what keeps you up at night?
At 1:33, the floor just in front Steve’s left foot doesn’t seem to have a limber hole...Are my old eyes playing tricks on me? 😁
You're right, but that's intentional. They said in a previous video that they expect to get a lot of water there, so the floor is supposed to act as a dam and they will install a dedicated pump.
Next time a couple more passes with the circular saw would clean out those groves completely. 1 or 2 minutes, no need to chisel or use router plane.
Sort of exhausted by every reasoning and reason for every decision and move made on this boat. Some are okay but dang..
You mean, on some boats, the Mast has driven through the bottom of the boat? Cause the shrouds were too tight? I'd like to learn more about that.
Good morning from southwest Florida.
We'll be sending some warmer weather up to you guys soon lol
Notification came in Friday 7am here in northern Ontario. Great progress guys, thanks Ben.
So is the weight of the mast step going to be concentrated on those groves where it slips over the bronze floors, or will the step slip down far enough so that it rests on the keel?
I really wanted to see more of the finished installation of the mast step. I need closure, lol.
Cool. Heavy Duty. So how much does the mast step weigh?
When do you plan to get back to finish the planking?
It is really a great sight when looking down the length of the inside of the boat except for the missing planks.
Good work getting all the bronze floors done.
Spring and warmer weather can't come soon enough!!!
Soon! thanks for the kind words, and we agree about the warm weather. COME, SPRING!

Each week is new and interesting, I am a woodworker also, wood turning cabinet and furniture making. I am always impressed to see your consistency and perseverance in tackling the opportunities that your project has presented.
Don’t forget to let a recess into the mast step to hold a lucky silver dollar.
Only 13 views, damn I'm early.
I don't understand the video digression starting at 13:46. Was that an editing error?

Sensacional! I am one of those that don't get a notification anymore. I will be waiting for the newsletters.
Thank you Ben for the new volume of your music. Bought, downloaded and I'm enjoying it very much.
I don't have the bell activated. I use the subscription tab to see if there are new videos
That is exactly where the videos sometimes don't show up if you did not activate the bell. The Subscription Tab is also influenced by the algorithm! If you don't watch a channel regularly youtube will show you less videos of it in the Subscription Tab
@@99Etien the subscription tab is NOT www.youtube.com it is ruclips.net/user/feedsubscriptions where ONLY your subscriptions are listed. I'm NOT referencing the page where you can see videos of channels you are NOT subscribed to! This page has never failed me and I visit it several times a day when I have spare time.
Why not just make it thinner instead of notching?
whhaaat??? I was recently unsubscribed somehow, geez .. devoted fan here! .. Resubbed and hit the bell .. keep up the good work! #peace
Interesting! Thanks for comin' back.
Hi, a question if possible. Why are the ends of the bolts (stainless steel) sticking out? I assume they are temporary, waiting to be replaced by copper rivets. This boat you are building is a dream come true. Congratulations, she will certainly be a masterpiece.
Temporary, yes. That's where the bilge bands will go.
Signed up for the newsletter.... gonna be a beautiful boat guys..
Just curios, which will happen first? When will the next human walk on the moon, or when will the Toronto Maple Leaf's win a Stanley Cup or will it be Arabella floats and sails off into a beautiful sunset? No pressure guys.
Or Project Binky will be completed (ruclips.net/p/PLGSOZAHg1yQHU1tc_3Y5MTQg1qjtxA_nq) :P
As you said this I checked my notifications and it had been switched off had to re set it regards from the UK
Why sell the parts? You should auction them, then you don't have to guess at what someone will pay, the buyers decide. (And you make more $$$)
Interesting idea, Steve.
I'm sure you love hearing minor worries from random viewers, but is there enough clearance from the sides to the mast step to the sides of the floor athwartship braces to allow the step to swell when it gets wet? It looked pretty tight in the notches in the floors that you cut. Even four big bolts isn't going to keep it from swelling a bit at the bottom. I don't know how green that wood is, but live oak can shrink or swell 6.6% radially and 9.5% tangentially. www.wood-database.com/live-oak/
If that's clear as mud, let me put it this way: if the mast step swells, are the sides of the mast step going to press on the bronze floors anywhere?
Don't forget to put a coin under the mast. 🪙
to much time lapse vidsin video now in the last several
Be nice if you guys could throw some support (via messaging to your followers) to Leo in his battle with the county. Keep up the good work!
Thanks for the kind words! We don't think local officials would like getting pounced on by thousands of people, and in smaller towns, it's not necessarily a good thing that out-of-towners would try to influence what is, essentially, a community decision. In this case, calm and peaceful is the way. The parties involved don't need a battle, they need a truce.
Acorn to arabella branding iron for all offcuts
I don't get why you cut up the floors, that must weaken them pretty badly. And please cut off those bolt ends before you pierce yourselves falling on to them!
That cutting really hurt. Especially the sharp 90s. Not a fan.
Hi Gentlemen, I know you have a lot going on but I thought of an Ide athat may be something popular with the viewers and make you a little money. take some of the off cuts of wood and brand the acorn to Arabella logo into them you can have a branding iron made cheap easy and I know I would love to have one for my desk.
Just don't send it overseas. Unless you want to be responsible for exporting pests to foreign countries. Send it to Australia and you might find the fines exceed the profits by a factor of 10. Probably even more if you send it to New Zealand.
I always enjoy your episodes because it reminds me that there is so much to learn. Thank you
One thing I like to have in the video, if it doesn't create more work, are measurements and temperatures translate to metric system for us European folks thank you very much for all the content
Ah, that's a great idea, @grumleyf. We'll see about that getting potentially edited in.
I am surprised you have chosen to set the mast step on the edges of the bronze floors.
I would think the stress concentration would let the floors act like knives or wedges that would cut into the mast step.
I think you need to add pieces of bronze to spread the pressure on the wood mast step timber.
Thanks for the vids
Chafe never sleeps.
Floor is too narrow from my viewpoint. 🤓
