Recently got a new-to-me Enco 111-1445 lathe. I've been going through all functions and haven't been able to get the quick change dial to move. I've removed the knob and have tried rotating it with channel locks and still can't get it to move. I don't want to get too aggressive with it and mar up the knob shaft. No matter which position any of the other levers and chuck are in, it won't move. I'm at the point of tearing into the gear box but wanted to check and see if anyone has any recommendations before I tear into it. From what I've read, this lathe is pretty much a carbon copy of a Grizzly 0749. I've been into gearboxes before, but not one with this many gears. The exploded view of the gearbox is pretty intimidating.
