Mini Laser-Cut Boat

This is really interesting. This guy designed and manufactures laser-cut flat pack boats. The thing I was most interested in was the puzzle cut plywood joint. I was thinking if there was a template for these puzzle joints you could cut them with a router and patterning bit and not even need a laser cutter. Seems like it could be a really good way to join 8-foot sheets. Do you guys think the puzzle joint would be as strong as a scarf or butt block?

There was a discussion on these puzzle joints a while back, and I think there was a Zip built with them. I think one of the Eastern marine plywood sources (CLC?) offers this kind of joint.

Bateau offers the puzzle joints as well. $20 per side on a 4’ sheet.

I would just be interested in a pattern that you could clamp to the end of each sheet. Then rout it with a pattern bit. Seems like it would be much easier than a scarf joint (if you have a pattern). Maybe there's a way to print the pattern and paste it to a sheet of plywood. It would be fiddly to make the pattern but once you did it would be trivial to make copies.

Pattern is simple to make. Take a strip of plywood 4’ long and draw some puzzle joints down the center line, cut it out with a jig saw. And you’ve got both sides of the pattern.

Seems to me that the kerf of a jig saw blade would be about the what you want for a gap between the puzzle joints for epoxy to fill... unlike in the vid where he said he had to hammer them together :dunno:

Matt, if you had one sheet with the puzzle cut it would be simple to make a pattern with mdf and a router with a flush cut bit.

Interlocking foam mats would be a good pattern if you want them all symmetrical.

(Anyone with young kids probably has a play mat that would work)

Or just draw the puzzle joint line on one sheet, overlap the two pieces edge to edge by the width of the join and cut thru the 2 pieces on your line.

But why limit yourself to puzzle joints,... this could be a new way to add a little customizing.


You could use your EKG graph. Or the DJIA chart, your favorite president silouhette, a mountain range profile. The possibilities are endless :lol:

I have a Carvewright woodworking CNC that might be perfect for making a pattern. If anyone is interested, once I get the shop set up (in the next couple weeks), I'd be happy to make something to be used for someone as a trial. I am NOT looking to make any money off this and right now I have plenty of 1/2" plywood scraps laying around.

Let me know if someone is interested, and has a little patience.
Happy Boating,
Tracy

If I was at the point in my build where I was joining panels I would definitely be down for trying it out. I'm gonna have a deck joint but it won't be wide enough to make it worth it.

I was searching for a plywood source. I found this website: CLC boats.com They sell plywood with the finger (puzzle) joints machined on one or more sides. The machining cost was acceptable, for the benefit it provides.
