how to they get wooden wings to bend on this slide-seat rig?

http://www.boatdesigns.com/Sliding-R.../products/188/

Looks like something that requires you to fab your own high quality plywood, which could entail high quality forms, presses, epoxy, steam, lots of time and effort.

Wouldn't make more sense to bend some 1/4" 6061 and weld in a brace if needed? Any shop would do that in 10 mins for a 12 pack.

I don't remember but the same plans are available on other sites for nothing.
This is really old from Popular Science or Popular Mechanics.

There is even a SOF kayak designer who tried to pass it off as his work.

Not really. Those outriggers should be pretty easy to laminate. Can't see it being an issue for anyone who has done a bit of laminating before.

seems like it would a pretty big chuck of lumber to make a form big enough to do something like this.

Take a bandsaw to a 3'x1'X6" header block?

I Agree, the wings look fairly simple to jig up. A simple form screwed to a table, some clamps and veneers. Steaming wouldn't be necessary, though a heat gun could help speed things up, if the veneers are fairly thick.

Not really. Just some 4x2 offcut blocks screwed to an MDF base board. Should be adequate.

Although personally I'd probably steam the laminates first anyway. I generally prefer doing it that way. It's easy to do. They dry off fast in decent weather, and are easier to deal with when gluing up.

We used to make longboards (as in the skateboard type), the shapes of which were far more complex than that ... we would make the forms out of rigid pink insulation and stick in a vacuum bag. If it wasn't a complex curve we'd even do away with the bag ... 1/16 maple veneers, birch veneers and 1/8 3ply baltic birch ply were the go to materials.

If I were making those wings I'd be tempted to start off by strapping 3 sheets of baltic birch ply around a metal barrel and glue with Titebond 3.

Cheaper/Easier???

I would like to know where this "any shop" is that will do this in 10 minutes for a 12 pack.

the sides of the slide seat system where the riggers mount have to withstand all the force... so have to be beefy... and the riggers have to clear the gunnel anyway...

so the other designs out there that just mount onto the gunnels and bridge from gunnel to gunnel.. like this one

http://www.gaboats.com/tutorials/outriggers.html

make a lot more sense, if you are ok with mounting things that way... probably save weight and work...

Used a 5/4 ie 1.25inch cedar deck board myself, two half lap joints expoxied to make my "wing" style rigger as above ...but "U" shaped vesu "V"

lot of hrs on it and it is still going strong.

Mike,

I didn't see your picture. Please.

This type of a installation is so you can easily remove the rowing rig.
2 to 4 screws or wing nuts and it's out.
Minimal cutting up of your boat.

Similar in concept to a Piendosi unit.

Thanks Mike.
Looks good for a fixed installation.
I assume it wouldn't take too long to remove if you ever desired - Just to use the boat as a canoe, of course.
