I have not used my 4x5 Cambo for quite a while. Yesterday when I was using it, I was surprised how difficult it was to insert and remove sheet film holders. Not just one, but all the holders I tried. Some were fairly new and others well used so age didn't seem to make a difference.
I was thinking that I might want to lubricate the metal areas along which the sheet film holders slide to reduce friction. The first thing that came to mind was some sort of silicone-based lubricant. Another idea was bee's wax.
Does anyone have a suggestion? Should I also consider some of the lubricant on the sides of the film holders, too?
The Cambo sheet film back is one that rotates but does not have a bail so therefore I have to fight the spring to insert and remove the film holders. I wonder if Cambo ever offered a rotating back with bail? Hmmm... I'll have to research that.
Thanks,
Terry
