Tonight I had the power drawbar removed from my mill, and I noticed that my drawbar only threads into my collet by about five turns. The threads are starting to show signs of damage from having to spread the clamping force over a small amount of threads.
I'm wondering if I've got an oddball drawbar. I would be grateful if somebody here would take a tape measure to their 1100's drawbar and let me know what they get. For comparison, my drawbar is 11.5" long from the shoulder to the end of the threads, and 12.25" from end to end.
Also, is there a maximum air pressure for the power drawbar? The manual says "90 PSI minimum" but doesn't list a max. My compressor goes up to about 150, and I don't want to damage anything.
