I purchased some UHMW the other week and one of the things I made was a new rabbeting fence for the tablesaw out of a piece of the plastic. This type of addition to the tablesaw allows you to make more accurate, safer, repeatable rabbet cuts on edges of boards without placing your nice fence in close contact to the blade. Allows you to bury the blade into the jig for a much nicer cut. I hope to show this during the process of building my walnut box.

I have not worked much with the plastic but find it very easy to machine and makes great jig parts. One of the fliers in with my UHMW had a web link with some additional information.

The jig is basically a 3/4″ thick piece of UHMW that has been cut down to be as long as my tablesaw top and a hair shorter then the height of my fence. This allows me to realign this jig to the same place against the fence each time using the tablesaw top, given they are the same size. I then drilled two 3/8″ holes all the way though at each end so I could then flip the jig and use the back side down the road when the first shows wear. The 3/8″ holes hold the Universal Fence Clamps made by Rockler which I picked up during a sale but never really used till now. They seem to do a good job holding the jig in place and tight against the fence, and I like how the clamps are out of my way during cuts.

I did smooth both sides of the UHMW with a cabinet scrapper and a little sanding making it almost like glass. Looking forward to really testing this new setup out when I cut rabbets for my veneer top panel of the walnut box.
