Hey guys, I make a lot of picture frames. That means cutting mat and glass. I’ve been thinking up some plans to make a mat cutting jig and a glass cutting jig. Basically a shop made version of a Logan mat cutter, if anyone’s familiar. I’m looking at UHMW plastic for the “fence” material - the fence that the mat cutter or glass cutter will ride against. I’ve never used it, so I’m wondering how rigid it is. Basically, would a 1/8” thick 3” wide piece of UHMW plastic sag in the middle over a span of 4 feet?
