I was thinking of a piece of 3" alluminum "I" or "H" beam, (Which ever you prefer) would do nicely. Light, NO flex..OR a nice alluminum LEVEL would work well layed across the wood the sandpaper is bonded to. It too, will not flex.deadedith wrote:I try to keep my hands toward the outside of the board but yeah, a metal piece would be good, the stiffer the better.
