Hello: I work as a postproduction operator on a TV network and before this I worked as a telecine operator and the only different cores I found in all my life were the RTF (Radio Television Francaise) cores that are totally different to the others. So, I don´t know what kind of cores are you talking about... All the other cores can be mounted on a split reel. An for the arms they are the image film take-up reel arms, not the Sepmag (separate magnetic) film ones that are mounted on top of Bauer B14 Studio projector. They are a couple units of the reel arm that´s mounted on bottom of the projector and very similar on design to the ones used on Bauer Selecton II 16mm pedestal (standard and Double Band) machine for taking-up film. As for the inverter, I suposse that a Lenze or Telemechanique will work for the motors on single phase AC power.
The projector is a portable machine but sits on a home made pedestal to install the reel arms.
Alejandro.
