The film cement arrived yesterday so it was time to get the 30 year old film splicer out and dust it off.
This German model replaced the cheap Prinz (Dixon's own brand) one that I originally bought.
The operation is quite simple; you place both pieces of film to be joined in the right hand side and trim them. with the cutter on the arm. Then, as you swivel the right hand side film holder through an arc, the cut ends pass by a battery operated grinding wheel that puts a bevel on them. You transfer one end to the left hand side, brush a little cement on the cut end, close the arm down and let the cement set for about 30 seconds.
Voila, a splice that shouldn't stick or break as it passes through the projector gate.
The other splicer I owned was a tape version. It did make very secure splices but when you wanted a lot of edits in a film, it got to be expensive. When I eventually sold my sound projector, the tape editor went with it.
So there you go, another piece of 70s technology that still works today. Oh that I was in such good condition thirty years on ;-)
