I recently had a TTS holder pull out which is very rare for me. I have always followed the clean/lube practices and been able to mill to the machine's power limits and even in chatter situations without pulling out. But this happened with a relatively light load so I am trying to figure out why. My mill had been sitting for about 3 months and last time I used it, it was running great.

I have an 1100 Series II and my instruction manual has 6 bellevilles stacked ()()(). I am looking at the newest instructions and it looks like they went to 8 washers. Why would that be and what do you guys recommend I go with?

My compressor fluctuates from 100-120PSI before it starts up again, so I always set tension so it will just barely release at 100psi.
