Hi Nick,
Well it was down to your encouragement that made me decide to use 52 cameras in the first place....Made work for me have but have to confess I'm enjoying it
Cutting the sheet film:
Bear in mind I don't have a dark room so have to mess about in a changing bag...somewhat interesting/frustrating at times!
Firstly I cover the red window of the camera on the inside of the camera door using old backing paper from film stuck down with gaffer tape. One time I did cover the window from the outside and learnt the hard way that the gaffer tape can cause damage to leatherette when removed!
I use templates for the cameras made from cardboard although I must admit that something more solid (perspex perhaps) would work better as it is too easy to cut through the cardboard template when cutting the film in the dark!
Often several pieces of film can be obtained from one sheet but don't forget which way up you have the emulsion side!
Sometimes the film will sit in the camera in such a way that it cannot move.
In those where the film can slide about, I place a couple of tiny slithers of cellotape inside the camera like little tabs sticking up from where the spools reside. Once the film is in place, I simply bend the tabs over so they hold the edge of the film.
Only requires a tiny bit to stop the film moving around.
Once the shot has been taken and the film removed for developing, I immediatley remove all the cellotape/gaffatape etc ....I don't like to leave it i place longer than necessary.
As for developing tiny bits of cut film such as little strips for the coronet midget, the problem is how to ensure they stay inside my patterson tank when changing chems etc.
I use 35mm film canisters!
Complete with lid, take a drill to them and fill them with holes.
Ensuring that water will flow in and out of them without restriction.
Be sure to rub down any burr etc especially from the inside where the film will be.
The piece of film now goes into the canister which in turn goes into the tank.
Develop in the same way you would tacos or roll film.
Simple but it works a treat
