I have a video coming up someday on the subject. If you have no lathe, use a centerfinder on large stock and a BELL center punch on small material.

how do you handle backlash going forth and back X and Y axis?????

[mrpete222]

@quadcatfly I have a digital readout (DRO) on the mill. This eliminates the need to compensate for backlash..

I was cleaning my desk the other day and found an article that appeared in Model magazine in 1973...by Tubal Cain. Thanks from all of your former, present, and future students. We appreciate your efforts!

[mrpete222]

Thanks, but that tubalcain is from England. I think he is passed on.

Thank you for posting these videos. They are very well done. The quality is just outstanding. The video is well lit. The audio is great. And the information is presented in a clear easy to understand manner.

Periodically, I check Youtube for instructional videos on manual machining and usually find myself frustrated for lack of finding much worthwhile. This time, however, I struck gold.

Thanks again. You are definitely one of the good guys.

[mrpete222]

Thanks for the encouragement.

In the first part in the X direction, after setting to zero and turning in the other direction and reading 0.01. What do you do after? Are you moving the table to get the zero on indicator and turning the indicator to the other side?
