The camera is an 8x10 Korona Pictoral View. Right now the main bed just has a sliding rack on it. There is also a knob that is used to tighten/loosen the back to this rack. The rack is probably about 10-12" in length, and if possible I'd like to replace it with a geared rack, and hopefully be able to switch out that tightening rod&knob for a geared one as well.
Thanks for the suggestion of talking to David. I completely forgot about him. He steered me in the right direction when I needed to make a new baseboard for my D5XL. I'll swing by there tomorrow and see if he can recommend anyone as well.
Thank you everyone for your help and advice!
