When I refurbed (new wiring, switch, motor) an old table saw I bought about a year ago, I put on a new belt. When using it I usually had trouble getting through the piece being cut. The blade just slowed down and stopped. Of course, I was mightly unhappy with this. I had put on a 3 hp., 220v motor and figured that would cut OK. When I calmed down and checked things out I found the belt loose. Puzzlement , it was new from Orschielns. I adjusted the tension and resumed cutting. Same result. Finally concluded the belt was stretching, and stretching and stretching and......... It is now at the max adjustment. Just how much is a belt supposed to stretch? And what is a good belt? I need to replace this one.
