Congratulations David,
Apart from some very old Myford catalogues, I can’t help with any paperwork. However, it looks like you don’t really need any.
I’m reminded that we had one of those capstans for the Super 7’s in the toolroom where I served my apprenticeship. I couldn’t see myself buying one for my ML7 so I made a version of the type which sits on the cross-slide. You can get a sense of it from two pictures I’ve posted via the http’s below.
I didn’t however, get to finish the depth indexer which I designed to pass along the lathe in place of the tailstock. I’d arranged for it to be coupled to the underside of the capstan head and geared 1:1 via a couple of 45 degree bevel gears. This would ensure that whichever capstan station was selected, the indexer would also be positioned at that station too.
There wasn’t enough height to tilt the head as with your C7 version. Nevertheless, it served me well for several production-type operations especially machining out the bores of those plastic (acrylic) valves.
I’m sure you’ll enjoy the extra versatility from having the C7.
Regards,
Sam
