Actually should be *BUILT* thread... need to sand the edges on some parts regularly and want to keep it jigged up so I won't have to keep re-measuring and changing it frequently, so I built this. The holes in the front plates are for screws to act as stops and I can mount guides to it to keep the part being sanded straight. I'll probably make a new front plate later with the slotted areas on the sides recessed, so I can sand things that are wider than the plate (so the screw heads are not in the way).
