I wanted to see if anyone has some experience with the variable speed head on the Gorton Mastermil 1-22. Mine is stuck on one speed so the variable speed pulley system must be seized up. I bought the mill cheap because it was not able to be powered up and it had been sitting for some time so I am not surprised the variable speed adjustment is frozen. When the spindle is powered up and I try to adjust the speed, the adjusting hand wheel only turns maybe 1/2 a turn in either direction and then drive belt starts slipping the more I try to change the speed. I have the maintenance manual for this mill, but it only describes taking the head apart to replace the drive belt and bearings. Before I take it that far apart, I wanted to know if there is an easier way to free up the pulley halves because there is nothing wrong with anything else in the head and I would rather not disassemble the whole thing if I don't have to.
