Cheers guys, I have all the gears and a chart for them. I have managed to figure that bit out, but I thought you were meant to cut screws on a slower speed than what you would use for turning? I think I might have figured out why it looks so strange, it looks like a belt has snapped in the past. Instead of the correct belt being installed someone has put one on that is far too large. The motor has been adjusted all the way out amd the drive pulley pulled out by 20mm to take up the slack on the middle position. I took all the belts off along with the pulleys, cleaned it up and refited with the pulleys in line, the belts don't come anywhere close to fitting. I have ordered the new belts in the right size, along with a new qctp, holders, tools and a 60 degree threading cutter. As far as the speed is concerned I'm sure the clarke can go down to 160rpm, is that slow enough or do I need to make a hand crank for it?
