About 3 yrs ago I changed the belt on my HF 34706 lathe. I remember that it was not the easist thing I've ever done. The Reeves drive made it a bit more difficult. Now that I have my motor running again, I tried to reinstall the belt today. I opened the front pulley wide open by moving the control handle to the highest speed. The back pulley on the motor is closed. Using the same belt I removed three days ago, I can not get the belt on the back pulley. I've tried all the tricks I know, using a screwdriver, working it onto the pulley a bit at the time, etc. What am I missing here?
