  • The process for facing is the same as shaving, but the increments are much smaller: .005-.01”.
  • Facing is used for the last few cuts of a part to achieve the smoothest edge. The smaller the increments, the better the cuts.


Tapping

Preparation

  • The process of tapping creates threads so screws can be inserted into parts. 
  • Make sure you have tapping fluid ready.
  • Insert your tap into the teeth of the tap wrench and twist the body of the wrench till the tap is tight.
  • Place the red handled c-shaped wrench on the chuck and pull down hard to make sure the tap wrench is placed securely.
  • Make sure the lever on the side end of the lathe is pushed all the way in. This is SUPER important to ensure there is no damage to the tap or part. You can even hold it in place when you are tapping to make sure it stays in place.

Steps

  1. Place your part at least 70% in the lathe.
  2. Turn the speed setting to the lowest. This is essential, as going too fast will likely break or weaken the tap as they are very fragile.
  3. Turn the black knob left and push the entire chuck mechanism gently towards your part until the tip of the tap is just against your part.
  4. Slowly turn the wheel (pictured) clockwise until the chuck mechanism starts moving into the part on its own.
  5. Once you’ve tapped halfway to the tap length, turn the black knob back to the center. 
  6. Turn the black knob to the right to take the tap out of the part (this is the ONLY time the lathe should ever spin away from you).
  7. Clean the tap and part with air.
  8. Repeat this process, this time going all the way to your desired length.
  9. Repeat this once again to ensure clear threads.
