Mill Z axis crank wheel

For anyone who wants to attach an alternative winding device to a Bridgeport here are the important dimensions for making a mating thingy.



I did the ultimate in geriatric aids, I added a motor, so the extent on my effort has reduced to setting a direction switch and pressing a button. No good for precision adjustment but the Bridgeport has the quill for that, and I did it to be able to still use the handle. Always seeking the easy way I also added some helper springs as in my previous post at http://www.homemadetools.net/forum/k...5951#post82823 which really makes the effort minimal.
