Unfortunately it's after loosening the lock, and adjusting that eccentric worm mount that I have quite a few degrees of slack in the worm. I'd had several goes at it, just in case another fiddle and wriggle would bed them better. I'll have to follow your lead, if I'm to see any improvement. > You'll need to drive it for some time to get it smooth, a variable speed > electric drill on the handle shaft works :) > > Beware though that shaft doesn't seize where it enters the eccentric. > Put plenty of oil on it. > > Well run in, and modified you should be able get the backlash down to > less than a thou. Now that's encouraging! I'm going to give all of that a go. I might try a cordless drill, with the torque clutch set low. It'll act like an alarm if it starts clicking. I have two with dead batteries. I can run one off a power supply. Thanks.
