Dividing head connected to x-axis feed on Bridgeport

Michael,
Thanks for the pictures, that helps a lot. I understand what you mean concerning the helix angle, and yours likely is the more practical solution.
The solution I cunjured up was to put the 90° head on the quill, and than rotate this head to the helix angle and mill on top of the blank like on a horizontal mill (clear as mud?). Since there are no angle graduations on the 90° head setting the helix angle might be a challenge though.

That should work - I'd use a sine bar or similar (basic trig and a dial indicator) to set the angle.

You have to 'nod' the head unless you're using the Y axis and cutting only short distances the other way.

Busy ATM - no time to find the photos I'm afraid....
