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.
  • 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.
  • The gibs on the compound need adjusting.
  • There's also a fair bit of backlash that can probably be improved with some tuning.
  • The pulley/belt setting to speed table needs printing out.
