I made a sanding table years ago from peg board that I enlarged the hole in and supported the board using small dowels to keep the board level but not block air flow.
I would like to cover that with a glued on router/sanding pad. My biggest fear is that spray 77 which I thought of using would just collect dust, and also get past just the glue-able area to the top of the pad, rolling on a contact cement would lead to the same.
How should I attach the pad to avoid gumming up the works? Thanks
