The process to convert a 1952 Adcock Shipley Bridgeport Series One “J Head” (Step Pulley) Mill with Bridgeport Vari-Speed 3 Power Feed, over to a Align brand CE 500 type “servo” power feed, utilising an adapter shaft.
This is the website link for the guy in the UK who can supply the Adapter Shaft for around $40UK Pounds (Sterling?), he tells me (after I’d already had mine designed from scratch, drawn up and turned).

He also has a KZfaq video all about the Adapter shaft and him doing essentially the same job I’ve done here, but his is more detailed than my brief overview here.

Hope this helps anyone else in the same situation out at some point, I’m sure I’m not the only one has wrestled with this issue on an old Bridgeport Mill.
