Small regularly repeating grooves on the comm after a cut

  

The cutting tool is not held firmly, and it moves while you are cutting. Tighten 
the two screws in the tool block that holds the cutting tool.

Cut comm does not have a mirror finish 

A mirror finish is not as important as a smooth comm surface; the comm 
must be smooth and even, as the entire burned layer must be cut down. 

A mirror finish does not affect the quality of the cut nor the performance of 
the motor.

Comm is coned after a cut 

To achieve the best motor performance, the comm must have an even (non-
coned) surface. That is, the comm’s diameter at the both ends and the middle 
must be the same. If the comm is cut conic, this means that the stands are 
slightly out of alignment. This sometimes happens if you have replaced a stock 
stand with the optional Axial Support, and that stand is not set properly.

Please refer to the instructions accompanying the stand to understand how 
to set it properly.
