I have a Porter Cable 3 x21 belt sander I use for preparing glued up panels. I've noted that the platen gets extremely hot and seems to affect the joint tape on sanding belts shortening life.
Has any one replaced their factory belt sander platen with one of the aftermarket ones that are supposed to reduce friction?
If so which ones are good ones and which should be avoided.
Where did you find them?
I've seen some Graphite platens, bout wonder if the graphite would leave graphite dust residue on the boards that would be difficult to remove.
