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
