Carriage Lock
If the carriage doesn't freely/easily move in the X direction, there's a fat hex bolt head sticking up on the right side of it that needs loosening.

Power Feed
Note that while generally gears/speeds shouldn't be changed while the lathe is in motion, from https://forum.protospace.ca/t/can-t-get-lathe-power-feed-to-work/3568/8
Set it to a lowish speed like 400 or less and bump the jog button. Then start wiggling leavers while it’s coasting down and watch the drive shaft and screw. You’ll feel it when it engages and the shafts will start spinning…
The threading lead screw and the power feed drive shaft are taken off at different points in the gear train. It is possible to jiggle a leaver and get one to start spinning while the other is still not engaged properly and requires further jiggling.
The XYWZ lever is the worst and usually requires persuasion to engage. The gears are all straight cut, and all may require sufficient wigglage before they cooperate. And the number dial is keep turning until it works. It’s about 1/4 past the number you want.

History
This lathe was bought by Protospace using funding approved for the purchase of new machine tools at the December 2015 members' meeting. It was picked up and brought to Protospace on 2015-12-22 along with the ACRA mill and the new 80-gallon air compressor. It replaces Kyle Paavola's lathe; it has equivalent capability. It came with the following accessories:
- 3-jaw chuck
- 4-jaw chuck
- Big steady rest
- Taper attachment
- 40-position tool post and one tool holder with a carbide tool holder in it
- Live center
- A carriage stop with a micrometer
- Coolant pump
