Assembly

  1. File:Athena sprung tool dressing.JPG
    Dress the print.
    Clean up the print with a small flat screw driver and precision mount. Clean the bearing pockets with the small screwdriver.
  2. File:Athena sprung tool reaming.JPG
    Ream the guides.
    Carefully ream the guides for the M3 x 35mm screws. DO NOT ream too much - the screw shafts should move freely but not cant in the guides.
  3. File:Athena sprung tool support.JPG
    Remove supports.
    Carefully remove the printed supports from the tool holder; pliers work nicely. Ream the holes with a 3mm drill bit.
  4. File:Athena sprung tool check.JPG
    Check fit of holder in mount.
    Check that the tool holder fits in the mount. The holder should move freely in the mount. Clean both as required.
  5. File:Athena sprung tool press.JPG
    Press in M3 nuts.
    Press the M3 nuts into their pockets in the tool holder with the pliers.
  6. File:Athena sprung tool clamps.JPG
    Start M3 x 10mm screws in nuts.
    Start the M3 x 10mm screws in the just-inserted nuts.
  7. File:Athena sprung tool assemble.JPG
    Assemble holder and mount.
    Place the tool holder into the mount with the screws and nuts on the top side of the mount. Rotate 60 degrees so screw holes align. Start an M3 x 35mm screw through one of the tabs in the top of the holder, place a spring on it and push it through the mount and then the tab on the opposite side of the holder. Secure in place with an M3 nylock nut. Repeate with remaining screws.
  8. Work the holder up and down in the mount, apply some grease to the screw shafts and continue working until the holder moves freely in the mount.
