I posted this previously but perhaps on the wrong place.
I have a question for someone who has more experience than I.
It is pretty simple to sweep the table in the x axis. However when sweeping the y axis, if you have to move the head, it isn't a simple + and - reading on the indicator as the center of rotation of the head is offset from the table. I have been toying with the idea of purchasing a cylinderetical square for this purpose. Then one could just mount the indicator in the spindle and extend the ram down the side of the square. Any comments??
This has always been a PITA for me as well. What I have done in the past to set the Head square to the table is to make a 12 by 12 by 2 inch thick Jig Plate. (This stays in my tool box) Then milled flat on both sides and an 11" Diameter 1/16 deep sweep area on the other. This of coarse was done on a CNC Mill which I hope you have.
Personally, once I set a Head it never gets moved again LOL. I buy or make precision angle sets to change the angle of the cut.
