Lathe is still being commissioned.

The lathe is this one [1]

instruction manual: [2] (local copy: [[3]])


Commissioning notes:

  • Excessive safety interventions that prevented the drill/mill feature being used have been removed. we may want to consider a new chuck guard.
  • It did run so could potentially be used, but I've removed the belts for now
  • The belt setup was weird, with a single belt between the motor and the spindle, when there was meant to be a jack shaft and two belts. there were two spare belts, but they didn't seem to fit correctly. possible a pulley needs swapping round, or the motor/tensioning adjusting. reading the manual may help. edit: manual read. no idler is a legit setup. its a very unusual arrangement. we'll need to print out the relevant page of the manual.
  • There was initially a rattle sound that was tracked to the motor pulley being loose. that's been fixed by tightening the grub screw. could do with some loctite.
  • The chuck also appears to rattle. one of the drive key parts seems to be loose.
  • The clutch to change drive to the mill head works, but there is a ~4.7mm (3/16"?) key missing from the vertical shaft, so the mill/drill can't be used
  • The E-stop switch was locked in and we don't have a key. I've fiddled with it so now the e-stop works but doesn't latch. We could do with replacing it.
  • The power feed works
  • We need a 10mm chuck key for the three jaw chuck. the ~8mm key for the 4 jaw chuck almost works for now.
  • The quill levers and fine feed both seem to be permanently engaged rather than selectable. The Spindle Feed Dog Clutch (A in the manual on page 11) seems to be stuck
  • We could do with a live centre as well as the quick change tool post (3 morse taper)
  • There are some weird plastic tubes, loose inside the base, not sure what they're for or how to get them out. The manual has an arrow pointing to them but no explanation (p14)
  • The gibs on the compound need adjusting (mainly because I completely removed the compound to investigate fitting a QCTP and didn't reassamble it exactly as it was.)
  • There's also a fair bit of backlash that can probably be improved with some tuning
  • The scale on the saddle feed handle is loose
  • The pulley/belt setting to speed table needs printing out
