I have tested and used my PC DP and there is zoo much run out. I think I need an after marketer Chuck and mate a new Arbor. I have looks at Jacobs, but would like a Chuck that isn’t made out of GOLD and or Platinum.

I cant spend more money on a chuck than I sent on the DP

Any suggestions

Hi Garbanzolasvegas,

Do you know if the runout is radial or axial? (See

The problem could be bad bearings or a defective quill shaft, or a bad chuck (since it sounds like you already suspect the chuck).

See if you can borrow a dial indicator to test the chuck and shaft at hand-turned speed, and also manually check for wobble at the upper and lower ends.

With the dial-indicator, also measure for runout with the shaft at the top and bottom of the shaft’s travel distance.

Let us know what you find out.

Try turning to spindle 180 degrees and see if it improves. I also tightened up the screw on the quill as much as possible while still letting travel smoothly
