I glue and clamp a module together, then 1/4 20 screw the modules to one another. Most of my modules have no fasteners at all. They are not needed when you clamp.
Even built a 160 MPH big block Chevy powered plywood hydroplane 7 years ago with no fasteners for the hull. In a few high speed crashes the wood fractured around the joints.
Individual modules are easy to modify in a change up. I have reworked previous modules easily extending or shortening the length or width.
When you bolt modules together always allow room to remove the bolts from the bottom later on.
Tight Bond original has a short open time and requires 175 lb per sq. in. clamping for proper setting. TB III is a tad more forgiving. Franklin will walk you through the differences.
