With female threads it would a braver man than I am. Even with inverter drive there is only 20 thou to play with. I can't rely on the drive to stop in 1/2 a turn. In my version the handle fits into slots around the circumference. Down the centre there is an adjustable rod which I can use as a backstop. If anyone is interested I'll put up pics in Hints and tips. Ray

424 forum posts 98 photos	Hi Nobby this is the handle I made for my Chester Comet. my lowest speed is 100 rpm so short threads are a no no under power. It's an expanding mandrel type. as you can see I have to open the gear cover to fit it so turning the power off is a must. Roy Edited By wheeltapper on 13/01/2011 11:36:30
