film drum dividers : LUSENET : Large format photography : One Thread

I just got a couple of Uniroller film drums and base, and I need to know how the film seperators were shaped that keep the sheets apart when developing four sheets of 4x5. I found in the archives of this forum where they were made of rubber and that they can be made from an eraser. Does anyone know how they are shaped? According to the old posts, a slit was cut into the rubber that slid over the dividers. I think I can build some o.k., but it would be nice to know how the factory one were shaped.

5/8" high, 1" wide, 1/4" thick, with a V cut into one of the long sides.

John, thank you very much. A couple of minutes with a razor blade and an eraser and I was in business. The measurements really helped. I have been running the drums with some old negs for about 10 minutes with water in the tank and everything is working great. It's nice when you don't have to re-invent the wheel everytime you try to do something. Great thing about this matter what, someone has been there and done that.

Hi Doug, I also heard about these pieces but never received any with my original purchase of my drum years ago. I decided to build them myself and here is what I created. I found a clothes hanger with plastic clips to hold pants or other articles and found that they were removable. I then just took a fine tooth saw and trimed the edges so that 2 sheets would comfortably fit on each side. These clips are plastic so they do not react with the chemicals and are rather easy to put in place in the dark. Also they are spring loaded and will NOT come off during use.

Good Luck.

Thanks, Grey Wolf. I will try your method also. The rubber clips are working fine, but your method may be easier. I found a couple of the clips in the closet. Time to get out the fine tooth saw.
