Andy. Have you had complete successe with these? I had a thread on bulk loading some weeks ago because I was having trouble getting my pentax MZ7 to fully rewind the film loaded into Jessops re-usable cassettes(plastic).
I just cannot figure out why this should be. They load OK and wind forward OK. When developed the spacing is fine too but on rewind the film sticks in the cassette. Not a problem if the darkroom is handy because I open the back and close it again and it rewinds a few more frames. Sometimes I have to do this a couple of times until it eventually rewinds the whole cassette.
Opening the back is not practical if I want to change the film when shooting. I have now used three of the 6 cassettes( bought brand new) and all exhibit the same problem.
It isn't the camera as it will faultlessly rewind shop bought cassettes.
What does cure the problem is firing the whole roll a couple of times with the cap on and rewinding each time, then retrieiving the end of the film, reloading etc. It is as if it frees the film in the cassette which then runs freely enought to rewind. It might not be a problem if I had manual rewind but this isn't an option with the MZ7. I can't keep on going through this rigmarole.
I wondered if I wasn't attaching the film straight on the spindle and it was rubbing the end of the spindle so tried to attach it very carefully the other night but it wasn't any better.
The spindle in the cassettes when empty spins fine and when loading into the camera seems to come out of the cassette about as easily as a shop bought cassette.
I am running out of ideas as to what is going wrong. Maybe it is the Jessops' cassettes hence my question about the Firstcall ones.
Any ideas from you or others will be gratefully received. Last time I raised this problem no-one else seemed to have experienced this problem. It's lonely when you are in a population of one!
Thanks
