Well I’d like to report that I was unable to repair my sanding belts.
I did have a success the next day doing something else.
My belts were 1” X 42” and were made with a Zerconia Grit and were 120 grit.
While talking to the supplier of these belts Supergrit in Gettysburg, PA I told her that the belts were failing after putting them on the sander. The splice is failing within 1 minute. She asked when I bought them. I told here maybe 5 years ago. She stated that was probably the problem. If the belts are not stored in an environmentally friendly area then their life is shortened. Humidity, heat and cold causes splice failure in belts.
But, I talked to her after I tried to repair them.
I had found on the web that a suggestion was use Tyvek as a repair bonding splice. I used a long cure epoxy glue to splice them.
This is the belt after putting on the tyvek patch. The tyvek is the product that is used on new homes as a moisture barrier.
This is the completed belt.
The glue on the surface caused a burning of the wood when sanding some mahogany. Sanding lightly stopped the burning.
Then it happened.
About 20 minutes after the belt was installed on the sander the splice failed. The Tyvek separated. The glue bond didn’t fail, the Tyvek failed.
The life on each of the belts were about the same.
I bought some new belts. She threw in a couple of free belts, Of course I lost 10 new belts.
End of story.
I bought a couple of ceramic belts that are used in knife making. They are working great on wood.
