I have a few cheap mag bases with pieces of plastic attached, Masonite would work just as well. I set them on the machine table to block chips. On the front of my Kurt clone vise there are two screw holes. I fit another piece of plastic about 18" wide to drop over cap screws in those holes. I try to machine in a direction that throws the chips forward, toward the guard on the vise. Some people with ram type machines have made brackets to fit under the ram to hold pivoted outriggers to support curtains, probably cut down welding curtains.
