Power Feed for Knee Bridgeport & Clones

[gatz]

Read many threads about buying or making powered Knee Axis for Bridgeports or clones.
I have spent many years moving the knee up and down and up and down at work and as a matter of necessity, had gotten used to it.
But now retired with a DoAll mill at home, I just don't need the aggravation.
Always seems that you need the table UP or DOWN; seldom where it's at, especially when milling the ends of a part, then drilling/reaming

I finally made an adapter to use a Milwaukee Hole Hawg as the power source. I don't think it will fail.

It dawned on me that you don't really need 9 notches in the adapter; just need 3 pins at 120º; 3/16 Dowel pins fit nicely in the slots on the sleeve of the Z axis of the mill. BTW, the Z-axis shaft on the DoAll is 16mm. not 5/8"
The pins are on a .65625R
The end that fits the Milwaukee was bored for a slip fit and keyed 5/16". The stock 1/4-20 LH shcs holds the adapter on.
If anyone wants a drawing, let me know.
It works really well and the low-speed setting on the Hole Hawg seems to be ideal.

You can find used Milwaukee Hole Hawgs on eBay occasionally.
Menards also has 5/8" corded drills which should have plenty of power too;
