Porter Cable DP Runout

Hi Garbanzolasvegas,

Do you know if the runout is radial or axial? (See http://en.wikipedia.org/wiki/Run-out)

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
