Depth is adjusted at the back end of the stylus.

DEPTH ADJUSTMENT

To adjust the depth you will need.

v

Piece of writing paper cut to approximately 1” x 4”.

v

Two identical key blanks – measure blade width with micrometer or dial calipers and select

two that match.

Before you begin please make sure that both vise jaws are in the standard “A” configuration.

Depth is adjusted by moving the stylus forward or backward by means of an adjustment dial located at the

back of the stylus.

Secure the two matched key blanks  - one in each vise jaw.  Please note:  Clamp the keys into the vise jaws

with about 1/32” gap between the bottom shoulder of the key and the left-side edge of the vise jaws.  

DO

NOT 

bottom shoulder the keys into the vises -  there may be a small radius in the corner of the key blank’s

blade and the bottom shoulder area.  Clamping in this area may ANGLE the key blank in the vise and throw

off your adjustment by cutting to shallow near the key head.

With the keys clamped in the vises and with the stylus adjusted forward about 1 turn - carefully release the

carriage and position it so the key in the left vise jaw LIGHTLY contacts the stylus about in the middle of

the key blank’s blade.

Observe that the cutter wheel missed the key blank in the right vise by carefully turning the cutter 

BACKWARDS

by hand  -  the cutter teeth should miss the key blank blade.  The reason for turning the cutter backwards is

to prevent any cutter teeth from removing material off the key blank’s blade before you make your adjustments.

Turning the cutter backwards will bump the key blank without cutting it -  if the stylus was not adjusted

forward enough to miss the key blank.

Upon verifying that the cutter wheel misses the key blank – you may switch ON your key machine.

Take the 1” x 4” piece of writing paper you made earlier and hold one end of it between the spinning cutter

wheel and the blade of the key blank.

Use your hand to slowly and carefully turn the Dial – at the same time we recommend that you slowly move

the 1” x  4” piece of paper from side to side along the blade of the key blank to assist you in detecting when

the cutter wheel’s teeth first contact the paper.  When the cutter wheel first contacts the paper the paper will

be shaved almost without any sound – you must back off the stylus very slowly for this to work.

Once you have the cutter wheel touching the paper you may slow down the procedure to very small increments,

1 number at a time -  each time moving the piece of paper from side to side in front of the spinning cutter

wheel.  Stop when the piece of paper is cut through to the last few fibers.  You have now accurately adjusted

the depth of cut on your key machine.
