I have an older belt sander that has a maple platen with some sort of frictionless material between the platen and the belt. Over the years, the platen has gotten grooves in it and the frictionless material has all but deteriorated. I am trying to decide between sanding the existing platen down and putting the frictionless material back on or possibly sanding the platen down and install a 1/4" steel plate to reduce the wear on the maple. I'm curious as to the need for the frictionless material over the steel. Can anyone elaborate on the construction of their belt sander? I primarily use this to sand headstocks and necks.
