Hi 'all,
I have a problem that has me stumped; the 2509n film holders rotate freely on the center spindle of my 2550 tank.
Having found nowhere any indication that it needs to be tight, I have used the combination on a rotary developer and only one sheet closest to the spindle came out. The other 5 sheets were lost. I used about 1L of dev and fix, so more than needed for rotary development. Given that the filmholder can rotate freely I am assuming that this is the problem. I have made a second attempt trying to lock the holder on the spindle with rubber bands, but they did't hold and the result was the same.

Before I get out the glue gun, does anybody have any suggestions ?
Your help is much appreciated
