Does anyone have any detail pics of their Ball Screw/CNC install on the Bridgemill?

I purchased a kit from Dan Mauch and the ball screws from Shoptask - was working on the Z Axis last night and from what I can see the ball screw for the CNC upgrade will require disabling the manual quill feed.

Also - I am a little perplexed as to the actual ball screw setup for the Z axis.

It seems that it would require removal or disabling of the spring return.

Any thoughts, comments, and pics would be appreciated.

Thank you.
Gary
