Quoted from Lovef2k:The bottom of the cab were the floor is notched in was splintering so I just chiseled all around and will add new wood to hold new floor in.
The bottom of the cabinet is 1/4" material which is notched in 1/4" from the bottom of the side panels. I built a new cabinet for a KISS restore I did and opted to replace the typical setup for the bottom with a piece of 1/2" plywood that is flush to the bottom of the cabinet. Same reveal inside but a much stronger floor and will resist the typical edge splintering. Since many of us lift these machines with hydraulic lifts, just made sense to me to make the bottom stronger.
