HOMEMADE
FILM CLEANER
LEWIS C. COOK
yOU got half an hour to spare? Two empty 16mm. film magazines? Six wood screws, a couple of pieces of wood and a few household nails? If so, you have all the makings of your own film cleaner. Here's how I went about it.
First round up the two small boards. As seen in the pictures, they serve as a base block and as an upright on which the units from the film magazines are mounted. Smoothly sanded off on the edges to protect the film, my blocks measured 6 inches long for the base block, 4% inches high for the upright, with common dimensions of a % inch thickness and a 3% inch width.
The parts purloined from the film magazines are as follows: two feed rollers, two takeup rollers, two film idlers and one spring gate clip. The six wood screws are used for attaching the four rollers and two idlers to the upright unit, as indicated. The nails — of two different sizes — are used (the larger ones) for attaching the upright to the base and (the smaller ones) for attaching the spring gate clip to a small piece of wood and it in turn to the upright . . . And, I almost forgot, you'll need one small piece of soft cloth, which is attached to the gate clip and provides the actual cleaning surface.
The relative positioning of these items on the upright should be clear from the side and front diagram and from the pictures. Perhaps I should add only that the feed rollers are the upper ones, the takeup rollers the lower. In use, the film cleaner is positioned in the usual way between the rewinds.
You should be able to slap the whole thins together in about half an hour, as I did.
