My apologies for the late response, and I'd like to tell you how awesome it was for you to take the time to not only type out the exact startup procedure for your machine, but to also include a video - which I did watch before it expired. That's a nice machine you have there! I don't think I've ever seen a 1981 F12 before, especially one that is still operatable after 40 plus years. The oldest Citizen I've ever owned and used was a 1978 "D-10". Hopefully I've attached a photo of it, as well as a photo of a 1982 "F-16" I currently own that needs motherboard repair, as well as the "L"-16 I am currently trying to get running. The "D" series operated very much like true Swiss type lathes (Tornos, Beckler's, etc.) where the turn tools don't move in the "Z" direction, i.e.: the stock is pushed through the bushing past the tools. The "L" series were also similar to them but have slide or gang type turn tool holders, and face drilling holders that move toward the stationary bushing where the actual "Z" axis cutting is facilitated by the spindle (with collect) sliding back and forth behind the bushing / headstock. My F-16 is posted on eBay if you'd like to see more, and I'll probably be posting my L-16 too. From what I saw of your machine on the video, it would appear the difference between your 1981 F-12 and my 1982 F-16 (besides the obvious max material size), was that mine had live tooling and secondary tool rotation in all 5 positions of both turrets. Thank you again for your time... it was greatly appreciated!
