Hi Guys,
I've just finished up my 8520 complete teardown, repaint, and rebuild. Every bearing in the machine has been replaced and all adjustments dialed in. The machine is very smooth and overall I'm happy. I'm a little concerned about some noise I'm getting from the machine at higher speeds when the quill is locked down. I'm getting ~.002 deflection in the quill when the quill is locked down. The noise is not coming from the spindle brake, it's a chatter at the spindle drive plate. Do I need to be concerned about this?
I do plan on adding in the Quill Drive Plate Spring Plungers. I'll likely do 3 plungers rather than 2 just to better center the spindle.
Thanks guys!
