+1 on the serpentine belt. I put one on my 9" South Bend, should have done it years ago. It made a new lathe out of it. Runs quiet as a field mouse with hiccups. I used a sharp woodchisel to trim it square to length, drilled holes in it and laced it together with soft stainless steel wire. I tried the Spectra fish line but that stuff cut it's way out of the belt in about 8 weeks. The stainless wire has been in there a year and looks like it was just installed.
