I'm about to rivet the inner walls back into our '65 Caravel
. I'm concerned about providing enough support for the overhead cabinets. I'd like to avoid the problems shown in this picture taken by the PO. (see below)
I'm thinking about drilling through the inner wall and the main support member. I would then epoxy 1/4-20 nuts on the back side of the support member "C' channel. This would be done before riveting the inner walls.
When I hang the cabinets, I will slot the wood to account for expansion and then through bolt the cabinets to the nuts that I would install now. This should avoid the problems with screws pulling out.
