Hows it going everyone? I recently bought a Clausing mk3. I rebuilt and repainted the whole thing and it seems to run pretty smooth except for one issue. The powerfeeds aren't working anymore. I didnt tear into any of the gearboxes. The leadscrew doesn't turn at all. Is there something real simple I'm missing?


Thanks

There may be a sheared pin on the leadscrew

Where the lead screw attaches to the feed box. Also look at the QCGB gears and see if they are turning. There is a train of gears and shafts from the spindle to the carriage. Work backwards and see where the disconnect seems to be.

Thanks. Figured out the lead screw. There was a locking gear that had slipped. Pushed it forward and now the lead screw is spinning. Now to figure out the power crossfeed.
