Joining plywood sheets. from jim michalak's boat designs. background... almost any boat you build from plywood will require panels longer than the 8' lengths you will find at the lumberyard. for an "instant boat" the usual manner of joining the panels together to get one long panel is with a butt strap or butt plate.. The “special” 16 foot plywood had been made that long by joining two standard 8 foot sheets, with a joint that looked pretty vulnerable and weak. i reluctantly bought the material on the assurance that it was plenty strong and i was not being deceived.. The butt joint is the most basic method for joining two pieces of plywood end-to-end or side-to-side to make a sheet large enough to suit a large bulkhead, make a hull side panel or anything else larger than the material that is available..
The best way to join 2 pieces of plywood edge to edge is to use a scarf joint. in aviation its the only acceptable joint. for me this was one of the hardest joints i have ever done. the proper way calls for a 1:12 joint. which means getting both edges angled to 12 times the thickness of the 2 pieces. the thinner the wood the harder it is to get. 3 plenty-strong plywood joints. plywood joints. plywood's multiple layers (or plies) make it more economical and resistant to seasonal movement than solid wood, especially for large panels. this joint matches a narrow dado with a tongue, created by cutting a rabbet on the insert workpiece. joinery or lumber and sheet goods. more joinery.
