Fixed the clutch. Seems the control knob didn't seat on the shaft shoulder which allowed the clutch thread to bottom out on the clutch.? Must have happened when she was new because there is no wear on any of the parts.? Works but very stiff. Awkward as well.? More tinkering to do I guess.? Pix of the open clutch included.

Well, then, I have a problem.? When fully engaged the carriage does not move under power but does by hand.
the assembly seems to be bottomed out as it cannot be disengaged by hand.? there was no spring to apply back pressure to the clutch.? Is a puzzlement.

Hi Larry
OK yes your Lot 5 has power longitudinal feed via the keyway in the lead screw that drives the worm? that drives the worm gear that houses the cone clutch.? The knob on the front of the apron tightens the cone clutch into the tapered bore of the worm gear.? All very simple and lot like South Bend Logan and other lathes of the day.

Greetings I removed? the lead screw from my lot 5 today for a good cleaning and , while I was at it, the apron as well. After removing 100 yrs of gunk I found................ no wear to speak of! no scoring, worn gear teeth, or sloppy half nut. I did find 2 small cracks in the worm gear carrier at the 12? o'clock position at its weakest point. I also found a cone clutch.? Is this used for turning?? If so, how does it work as I see no way to engage it. Anyway, the old girl is back together cutting threads like a champ. Any help appreciated. Be well Larry
