The two specimens I have wear the Cameflex and Aaton mounts. I can calculate and draw my own design but machining a new mount will be easier from a proper design.
My intention was to take the easy way out and machine up an ARRI standard tail, attach a PL-Mount adaptor and use shims to get the collimation right. Making the PL-Mount is somewhat of a challenge.
I have made them for other lenses and the similar IMS-Mount for a Speedbooster adaptation to the SI2K camera IMS-Mount. Small hobby lathes struggle a bit with the wider diameter of the PL-Mount.
Any advice will be greatly appreciated.
