My work table is a solid wood door . Its nice and clean. When I build model airplanes, I lay a piece of ceiling acoustic tile as a temporary topper because I need to stick pins to hold the balsa over the plans. I also have a very nice piece of 1 inch balsa butcher block that I use occasionally .
For non model airplane use , I am wondering what cheap wood to use as a sacrifice support piece when I need to cut through the workpiece with router or circular saw so I don't cut grooves or drill holes into my solid door work top ? I have used sheets of white foam but I hate the bits of foam that gets thrown all over the place.
Tks
