I just look at the box mine came in and it’s grinding instructions are not printed on the box. They may have been on a sheet in the box, if so I have lost it.
I do recall reading specific instructions for grinding them. At one time, I believe there was a web site either Trap Dude’s or someone who sold them. That’s where I might have seen them.
From what I recall, they stated a warning not to use a typical belt sander for wood, due to its high speed. It said the heat generated by it would delaminate the pad. It also may have stated the grit belt to use.
I can say....I used the typical belt sander thinking that I did not have a lot to take off....I will go slow...it will be OK. It looked OK when I finished it. After a couple of months it started to delaminate, rubber from the backing.
Freezing it sound like a good idea to me. Hopefully some one can find the true instructions.
Thanks Carl,
I was dead wrong about the belt sander speed!
