OK, here goes. I split a piece of plywood as a backstop for an indoor archery range in the basement. The hinge screws stuck out a bit and my wife scratched her hand on one. I took the ol' Dremel-style grinder and cut-off wheel to the screw's tip. Cut off the tip and then ground the shank down flush with the wood. Grinding stone was too slow. Hope this might get you started. BTW, I had two Dremel tools and #3 is Lowe's house brand that looks identical to the Dremel. Wouldn't be without one. Handy as a pocket on a tee shirt.
