Before I start let me say I know what I really need, a 6" Edge Sander with about 1.5 hp motor; however the $600-$800 price is not realistic. Would a 12" disk sander with a 8" x 17" table work to sand the edges of dovetailed boxes or cabinet doors? I have looked at the belt/disk combos but don't think the box could be held against the belt good enough to keep from rolling the edges or getting an uneven sand job. Will the disk leave too much swirl?
