Mark, The problem with going into the plywood with rivets. The wood will splinter when you squeeze the rivet without a back-up. However, you could back-up the plywood by placing an angle or a flat doubler behind the plywood to make a sandwich. That way you don't have the end of the rivet unsupported. I would be hesitant to use the pop-rivet back-up washers however in this critical area. Since this is a Firewall, you'll need to make sure that every penetration is sealed. I think a more elegant solution would be to use Avibank AVO337 blind panel fasteners to attach your cowl onto the airframe. You can find these at http://www.avibank.com These fasteners only require a .040 hole to disengage. --- Mark Jones <flyk...@wi.rr.com> wrote: > My thoughts were piano hinge on top of stainless > steel firewall on top of > plywood.
