3.Using the collar between the two cutters has the advantages and disadvantages of the first two procedures, and is frequently used where both edges of the work are to be molded, Figure 44.
Note: It is advisable to place the cutter as low as possible on the spindle to reduce spindle deflection and ensure the best possible finish. Also make sure that the contacting surfaces of the cutter are smooth, clean and without dents.
Starting Pin
Use of the starting pin should only be attempted by advanced users. If you have never used this method, it is recommended you get training from a qualified person. Failure to comply may result in serious injury.
The starting pin is used to support the work when starting the cut.
1.The work should be placed in the position 1, (Figure 45), using the starting pin as a support
2.Swing the work into the cutter as shown in the position 2. The work is now supported by the starting pin and the collar.
3.After the cut has been started, the work is swung free of the starting pin and only rides against the collar (Figure 46). Always feed against the cutterhead rotation.
