Frank,

I've built boats on just saw horses (kits) and on a 4x8x3/4 sheet of plywood with stiffener 2x4s down the sides supported on sawhorses (plans) and on a concrete driveway (winging it from an existing boat). The point is, whatever gives you sufficient support at a comfortable angle will work, especially on hulls in the 100-lb or less range.

If it was me, I'd go for at least 2 dozen spring clamps. More would be better, but 2 dozen would at least let you put on both rubrails at the same time.

Have fun,

Laszlo

Thanks for the reply Laszlo!

I've got a handful of spring clamps from other projects + c-clamps, pony clamps & others lying around so I'll probably get a couple dozen more sping clamps to start with. I can always get a few more if I need them.

Still working out my work space but think I'm going to make two 3'X4' work tables that I can push together to make either a 6'X4' or 8'X3' long work area. That combo really fits my workshop well with space all around to work.

I'm hoping to get everthing pretty much ready so when my break comes I can concentrate on the build. Would like to get it complete, or darn near, over the 9 day spring break.

Take care,

Frank
