Home Made Enlarger For Movie Frame "Blowups"
Here's Answer To The Movie Amateur's Desire For A Simple Means For Making "Stills" Of His Pet Movie Scenes...
1 DISCARDED coffee can, your projector lens, a bottle cap and a few boards, plus a few odds and ends such as nails, screws, wire etc. — with these easy-to-acquire items may be fashioned a simple enlarger that will enable you to make enlarged paper prints from your favorite 8mm. movie film scenes.
Every movie amateur has experienced the desire to see his "pet shots" repro
duced as still photographs. Thus far, no successful enlarger has been marketed for the amateur's use in blowing up 8mm. film frames. But why wait for the manufacturer's article when you can easily build your own enlarger? Actually, construction is relatively simple as may be seen from the accompanying diagrams and description.
In principle, this film frame enlarger resembles the ordinary photo enlarger

such as you would find in any darkroom except that it is designed to hang on a wall instead of resting on a table. The base is a piece of }/4" pine 5" wide and 26" long. Mounted at the top, by means of metal tabs, is a discarded 2 pound coffee can which serves as the lamp house. The lid, as may be seen, is fitted with a porcelain lamp socket which takes a 100 watt frosted lamp. The metal tabs are soldered to the can and attached to the base with nails.
A means for transporting and holding the movie film is attached to bottom of the coffee can after a suitable aperture is cut. This is shown in detail in diagram C. First an aperture the exact size of an 8 mm. film frame is cut in the bottom of the can and the edges smoothed with a file and emery paper. Two pieces of hardwood, which form the track for the film, are attached at either side of the aperture by means of small stove bolts, as shown. The track pieces are champered out on the inside edges to a depth corresponding to approximately the width of the film. Thus, when film is in place within the track, it lays smooth and level, insuring sharp and even focus throughout the enlargement.
