  • Oh No Not Another "z" Dro.

    This is the top of the caliper the Hope through the quill Ring is about .625 a snug fit,not a press fit will do.


    This is the bottom stand off.




    AT The Bottom.


    At the top.

    Now You to can have a Dro on your Quill for less than $20.00.

    I bet that makes measuring things tricky, what with there being a mill in the way

      It's similar to a Mic. stand.

        Good deal!

        I recently put one of the $30 Chinese quill kits on the mill at work.It took more time to make the little reader bracket than to mount the rest of the thing.
        I just need one more tool,just one!

          Good job,Wolf,but I advise you to grind the pointy bits off.They can really mess up your work with blood.

            What did you use to drill the hole? Did HSS bit work or did you use a carbide drill?

              Which hole Rotate?
              Actually it doesn't matter,it was HSS, as the head is cast, the standoffs are alum., and the calipers are Space age polymer (plastic).

                Don't those "space age polymer" HF calipers only read to .01"?

                Edit-- Question #2-- Is it just me or is your mill head missing its lower two mounting bolts?!!!

                  Thanks. I didn't realized that it was plastic. In the picture it looked like hardened SS.

                  I guess there's no need to grind off the pointy end.

                    Yes Paul, how often do you need to drill to +/-.001, and if you did there is always the Table crank.


                    The 2 bolts were missing and I used SHCS till I get some originals,Good catch.

                      Compare the third and fourth phototgraphs. Is it just me or does it look like the calipers are skewed to the centerline of the quill in the third as compared to the fourth one.
                      Forty plus years and I still have ten toes, ten fingers and both eyes. I must be doing something right.

                        Yes, the skew is more visible when the fingers are close together. In the other photo, they are far apart and the skew is less obvious.
                        That probably doesn't make too much difference, especially since he's not drilling to 0.001".

                        In any case, that looks like a fun improvement job, thanks for sharing the photos.
                        I've had a cheapo caliper I've been meaning to attach on to my lathe tailstock, maybe I'll get around to that one of these days.

                          That has been taken care of, and so was the sharp things.
