body mounting pads

 

On my table saw I was able to cut thru the stuff using multiple passes 1/16 to 1/8 at a time, and come up with the proper [using my old ones as a pattern] sized cord plyed rubber stock 1 1/2" by 3".  I marked the middles, then drilled 1/2 or so holes thru them, using a sharp spade style wood bit, which cut away the rubber and cord without tearing, burning, or grabbing.

 

You have to drill these one at a time or friction will give you a "black melt" for lunch and not return a drill bit in good shape.

 

I was even able to downside the 3/8" stock to make a couple of 1/4" thick pads I found I needed up front.  I don't think I could be successful making a 1/8 one, however--too thin to keep in control.  On mine I used the originals, which were in good shape.  If I put my mind to it, I suppose I could come up with something to use--Maybe a couple of thicknesses of a roofing shingle if you can find some without the "rocks" on it.  Maybe some pieces of old inner tube.  Maybe some pieces of roofing rubber membrane.  Maybe some hardware store rubber bushings.  Cut one out of your old boy scout web belt dip it it roofing tar and install it.  Dont forget to wash up afterwards.
