mr m nailed it, that is the only way to go. I have that table and will never need to buy another belt. I went to the hobby store and bought the mono filament thread (polyester) in the link. I made the jig that was shown in the instructions that came with the table (also on the website I believe) and for a few bucks I have a lifetime supply of belts.
