Great video, this is what I’ve been looking for. I don’t like the router-on-a-sled method especially since I don’t have a router but I do have nice sharp hand planes. Thanks for the video.
I also built 2 canoes with 4mm ply and simply glued the 2 pieces together plus fiberglass band, no scarf join. And they are still standing and doing well
@@wulkie I've replaced the full interior of a UFO 34, using the techniques of the Gougeon brothers. Scarfing, filleting and much more. It was a ton better than before. My comment was really to hasty, without any thinking. Must be all the years working with epoxy....some minor brain damage maybe? ;-)
I've got eight scarf joints in two kayaks to build, and I plan to replicate your method. I really like how you matched the angles by planing each side at the same time. Finally, the editing was great to just show us the essence of each step.
I am happy to read that!. Before scarfing i aligned the 2 planks and marked a long line with the pencil so that alignment will be kept even after the scarf. Just in case something could go wrong. It worked like a charm.
I just scrolled through the playlist - and 3 years later, you are still building this. WOW ! Is there a way you have calculated that specific angle while shaving off the edges ? ( at the 0:43 ). Thank you -
Looking for some advice on repairing a broken sailboat mast. I need to patch on about a 4' piece on the bottom. The mast is constructed with spruce using the bird's mouth method. I think some kind of scarf joint would be the strongest, but I'm not sure how to do it for this application. Thoughts? Cheers and thanks in advance!!
I would say, fit in new piece of wood as fit as possible and glue it with thickened epoxy. If unsure, post a photo on my FB page for a more objective opinion: facebook.com/WulkiesGarage
At 1:11 We see an outstanding, superlative result!!! I am not understanding how you accomplished this, even after watching the earlier one minute and 10 seconds of the video, as you used nothing to guide your plane except for your freehand use of that wonderful tool!!!
It is easier tham you think 😋. The ply has many veneers and when planing you start getting multiple horisontal lines. If all are parrallel it means the cut is fine. With the plane you just need a good enough pattern. All the rest will be sanded to perfection. All scarfs went good first time. Just need to make sure they are well fastened so they don't move
Cou can alternatively use the butt joint which is also super strong but does not look nice. If you can easily hide the joint, i would not go for the scarfjoint. Here is one project where i used the butt joint successfully ua-cam.com/video/SclraG9Rmc4/v-deo.html
Yes, absolutely. I did that for the gunnels. you can check it here: ua-cam.com/video/UtCIZNJW-0Y/v-deo.html in the meantime I have build a better jig for the low angle cut ;)
Does that shorten the overall length? If so, how do you calculate the total amount of 'extra' plywood you would need for two sheets? Thank you for the videos, they're awesome!
Yes. If your scarf is 5cm you need to shorten 2.5 cm from each side. I simply shortened 5cm from the bow pieces. I did not need additional ply. Later edit: you add 2.5cm, don't shorten
Pleased to see the advertising trolls have left this comments section alone. I looked at this companies designs whilst researching boat building. They look to be very nice boats. I found a wreck of a plastic boat to restore just before I committed my self, so it is still on my to do list.
hi everyone ,if anyone else needs to find out about build wood boat plans try Joolaim Rudder Replication (just google it ) ? Ive heard some pretty good things about it and my cousin got excellent results with it.
@@wulkie We are rebuilding the front storage compartment of our boat due to termites . Currently we r struggling to make it due to the curve structure of the boat and even cut too much of the wood required to make a supporting part 😞. Could u suggest me some tricks to avoid and ease us off doing this process... Please
@@jawbreaker54 for boatbuilding you need to make sure plywood is marine grade. That means it can tolerare wet conditions better than ususal ply. You may check with local supplier for such termite proof product... but i have not heard of it existing. What if you use insecticides to remove and prevent termites?
another video with annoying music. Pro tip , if you place the part to be planed on a block/plank, with the edge overhanging , you can turn the block plane on its side and get a true square edge
Great video, this is what I’ve been looking for. I don’t like the router-on-a-sled method especially since I don’t have a router but I do have nice sharp hand planes. Thanks for the video.
Having all the scarf joints on the panels at the same place is a good recipe for future problems. It forms a nice breaking line.
Actually, the scarf line becomes more solid than the ply itself
@@wulkie You're 100% right. I stand corrected, and was clearly not thinking clearly...haha. Please forget my dumb comment.
No worries. I was very skeptical myself at first. And i tested the strength of the epoxy first so i can remain confident

@@wulkie Terrific instructional video. Is there a preference of sequence ? Is it okey to first scarf join - then loft the boat plan ?
Sure. You can scarf join both sheets and then loft and cut. I will consider this option for my next one
Ha! neat trick to make sure the scarf joints are equal to stack em up! (y)
Bravo, Bravo! Felicitari pentru progres! Asteptam cu nerabdare next step!
I've Subscribed! I gave your Part 2 video at run through and Loved It! I thank you immensely for the improvement to your background music!
Perfect scarfs and i like the battery clamp
at the end the woods just moved by itself... nice!

Happy to have you back 😉. The rule of thumb is 1:8 ratio between thickness and the length of the joint. My ply is 6mm so the scarf length is 6x8= 5cm
Wood working is great. Your animations, too!

Man, you are a piece of work, doing carpentry in a pair of flip flops!
Real professional.

@@wulkie I'm going to try on some cheap, low grade ply. You've motivated me to have COURAGE! LOL
Great! Let me know how it worked out. Do you happen to have a router? That can save some big time
When sanding, use a large flat block. Mines could have been bigger for sure
Cou can alternatively use the butt joint which is also super strong but does not look nice. If you can easily hide the joint, i would not go for the scarfjoint. Here is one project where i used the butt joint successfully ua-cam.com/video/SclraG9Rmc4/v-deo.html
Capten ..henny here.. thanks
Hi Henny
Nice job,You glue the scarf with epoxy or?
Great Vid! My question is would you do the same with real wood planks?
Yes, absolutely. I did that for the gunnels. you can check it here: ua-cam.com/video/UtCIZNJW-0Y/v-deo.html
in the meantime I have build a better jig for the low angle cut ;)
that's a neat trick to use 6 dots to mark an 8" line
😜

Yes. If your scarf is 5cm you need to shorten 2.5 cm from each side. I simply shortened 5cm from the bow pieces. I did not need additional ply.
Later edit: you add 2.5cm, don't shorten
@@wulkie Don't you have to ADD 2.5 cm to each side?
Apologies!! You are right. You add 2.5cm. Don't know what i was thinking...
Hi, are you using epoxi alone, or epoxi plus thickener ?
Hi, for gluing the joints i use epoxy with thickener

hi everyone ,if anyone else needs to find out about build wood boat plans try Joolaim Rudder Replication (just google it ) ? Ive heard some pretty good things about it and my cousin got excellent results with it.
What kind of plastic are you using there to cover the joint during curing?
Hi. I use cellophane. You can use any plastic as it will not stick but cellophane is strong enough to not tear apart when you remove it
@@wulkie Thanks Cap!
The plywood is pre treated against termites right ?
No clue.

You can use a power tool on your scarf joints gheez.
No really, you only need two pencil marks, one at either side to make a straight line......
Music just killed it, nice video other than that.
Thanks for the feedback. I am open to sugestions.
