I am working on insulating our house with rigid foam insulation. I have 200 4'x8' sheets that I need to cut into pieces to fit between the floor joists and studs. It would be a lot of cutting to do by hand, so I decided that a table saw would work better.
I had an old worm drive saw with a broken handle. I removed the trigger switch and wired in a toggle switch. Then I cut a slot in a piece of plywood and screwed the base of the saw to it. Next I'll screw a 2x4 down to the plywood for a fence. Then the whole thing is set up on a couple saw horses.
It might not be the fanciest table saw, but it will help speed up the insulating job.
