I need to cut into some kitchen cabinets to install a dishwasher. I could use suggestions as to the best way to get a clean straight cut, from the floor to the bottom of the counter, with minimum chipping on the plywood edge. They are stained and varnished (years ago), and I would like to avoid having to change that finish.
I also need to cut the bottom 3/4" ply from the front to the back. Not so critical, but easy would be nice with the awkward access.
Tools I have: Hand saws, circular saws, router, sabre saw, sawsall, dremel tool, HF multi-tool.
