Thanks for the input guys. I am currently leaning toward the incra miter sliders because I don't have the right tools to get UHMW down to the right dimension. I have a DeWalt contractor's saw and they put this terrible rough coating on the table and miter slots. I had pretty good luck sanding it off, but it slightly changed the miter slot dimension.
Jerry I can give an answer on what UHMW is technically. It is ultra high molecular weight plastic. I believe this type if plastic is very strong due to the length of it's molecular chain. It also has low friction coefficient. I work on a supertanker, and all the fenders at the docks we go to are made from UHMW plastic. It is a very useful material.
