If it's an older one forget it, you can get a 3 axis Sino or Meister on ebay for around $550 posted and can pick the scale length. I have both of these DRO's and I have never had a problem in around...

I bought a HM52 over here in Australia and after receiving a replacement it was from a different manufacturer. The old one relied on the same set up as yours, but the new one had a slot in the quill...

What I do with my 3 jaw chucks is to machine the register on the back plate down a thou or 2 so the chuck can be positioned for the stock to run true.

Coming along nicely and I am glad the machining all went well.
