Time for a new 4-Jaw chuck - perhaps?

[Mayhem]

I had pretty much made the decision to buy it and the weekend work I just did will pay for it but I thought I would just throw it out there. You just never know when you will get that response to tell you there is an easy fix and to put the folding stuff back in your pocket!

I will be making my backplate, now that I have figured out the threading issue I was having. The backlash nut on the leadscrew had worked loose, so there was 2mm (0.080") of travel.
