Manufacturing and Assembly

Tools

  1. CNC Mill (3 axis is preferred though possible to do with 2 axis)
  2. Lathe
  3. Waterjet
  4. Taps

Fabrication

  1. Use the waterjet to cut the chipper arm sheet metal
  2. The 3 axis CNC Mill is used to create the chipper boot; kicker boot; front,mid and rear mounts, and the plunger stabilizer.
    1. When milling the front solenoid mount make sure to put in the bushing in the pocket first before you mill the section.
  3. Use the lathe and mill to create plunger.
    1. To do this, first create a hole in the both steel and stainless steel shafts with the lathe.
    2. Thread holes with a 10-32 tap and attach both shafts with the set screw. Use retaining compound on the set screw.
    3. Now turn down the created shaft with lathe to the desired diameter.
    4. Cut Shaft to desired length.
    5. Use the mill to mill down the shaft to accommodate the kicker boot.
  4. Rip off the casing of the push type solenoid to get the coil.
