I have all but eliminated cutter pull out on my 1100 Series II machine.

When Matt Deopers worked at Tormach he suggested I tighten the collet to when I step on the pedal for the power draw bar, it allows just barely enough collet movement to allow my TTS holder to be released.

I did that and the only time I get cutter pull out now is when I get a little too aggressive with my cutting.

After 7 1/2 years I have a pretty good idea what this machine can and can’t do.

Soooo.... Basically, "I have eliminated pull-out by never making any cuts that would result in pull-out". That's really not much of a solution. The only time ANYONE gets pull-out is when they "get a little too aggressive". You COULD make more aggressive cuts, if the PDB provided drawbar tension commensurate with the maximum capability of the rest of the machine.

The real problem is that, with the Tormach PDB, the "pull-out threshold" of the PDB is well below the maximum capability of the rest of the machine. Contrary to popular belief, this is NOT a limitation of TTS. It is a limitation of the Tormach PDB, NOT TTS, and NOT the rest of the machine.
