CK17 puzzle joint ended ply

Post by Jaysen »

Jeff/Jacques,

Looking at the ck17 plans, I'd prefer puzzle joints for bottom/side panels. I know if I splurge and CNC cut the kit, the puzzle joints are included. If I choose to "do it the hard way", do I need to change the nesting to allow for a 4" reduction for each piece of ply that gets a puzzle edge?

Alternatively can I accomplish the same idea, and have the same strength, if I just double up the glass on a typical butt joint?

Not necessary because the nesting is on standard sheets 96" long. Use real marine ply that is 98-3/8 and that leaves room for the puzzle joints.

The purpose of the puzzle joint is easy assembly with correct alignement. They have nothing to do with strength. No need to reinforce anything. Please build as the plans say: one layer of tape each side.
