I want to thank everyone for their response to my query.I shot a roll of Tri-X with my T4 and was quite pleased with the results.
I have a tip that might help those who bulk roll their film and also want to beat the automatic DX coding. When I first started to roll my own film I became flustered with the Kodak metal cassettes and their temperamental tops. A friend of mine who teaches photography at the local college suggested reusing film cassettes which were discarded by photo labs.It works wonderfully.I can even match the DX code with my bulk film (Tri-x and FP4).
Heres how you go about it. Get some good quality scotch tape and attach the small bit of film in the cassette to your bulk film. I stick a piece on the bottom portion first,then affix the top.Really make sure the film pieces are well joined by drawing your thumb nail over the tapped joint.Feed a bit of the film back into the cassette then roll away. This method works well for me.
NOTE:As in life the only sure things are death and taxes.I have had the film joints separate when using an automatic advance camera.Its a rarity but it does happen.You then must remove the film in a changing bag or darkroom.
