COLBURN LABORATORY Special Motion Picture Printing 995-A MERCHANDISE MART CHICAGO 54 with the film. When shooting the pictures, of course, start marks must be made on both the record and the film as a guide for starting both together later in projection. A nick in edge of film or a punch mark in the film just below the film gate usually will suffice. A small dot applied with red lacquer or fingernail polish on the recording will indicate the exact starting position for the playback needle. As may be seen in Fig. 2, coupling of projector with the playback turntable is by means of a flexible shaft connecting the turntable mechanism directly to the threading shaft of the projector. Almost every make of 8mm. and 1 6mm. projector provides a threading knob at the front or side of projector to which the flexible shaft may be coupled. In the case of my Eastman model 70 projector, the knob is conviently located at the front of the machine. The shaft is connected with the motor through a pulley and v-belt so that no strain is placed on gears of the projector mechanism when tapping this shaft to drive the turntable. This knob was found to rotate twice for each frame of film. In order to match the 10-to-i ratio at the camera and give 10 frames of picture to each revolution of the turntable, I had to have a 20-to-i ratio at the turntable. I purchased a used record player and removed the rim-drive and motor. Thus, only the turntable, pickup and cabinet were used. I then built a worm and gear drive from a 20 tooth gear plus a section of a 3/4" 10 T.P.I, bolt for a worm. The main drive shaft holds the worm, A governor from an old discarded spring drive phonograph motor smooths out the rev action. The turntable was fitted through a rubber disc drive to the 20 tooth gear. Coupling of turntable and projector was then effected by means of a length of speedometer cable. Cable was joined to the turntable main shaft by soldering small brass couplers on the ends of the flexible shaft as shown in the "Phono Drive Connection" diagram. A similar coupler was soldered on the other end of cable to provide a connection with the projector. At the projector, the escutcheon plate around the threading knob shaft was replaced with a brass plate to which was soldered a short collar with a male thread. This served to take the coupler of the flexible shaft, enabling it to be screwed up tight to form a positive fit of flexible shaft and projector shaft. The same treatment was given the joint at the turntable and details of these connections are shown in the diagrams. For amplification of the recorded sound when screening pictures, my regular recorder amplifier may be used or the leads from the pickup can be connected to the house radio for amplification. In the latter case, the volume control at the turntable may be used to regulate the sound. What has been done here with a Univex camera can likewise be applied to almost any other make of cine camera. Some camera mechanisms are more adaptable than others, of course, and the necessary alterations obviously should not be attempted without first studying the camera thoroughly. Coupling projector with turntable is an easier task, in that the universal feature of threading knob on most projectors makes the drive shaft connection relatively simple to achieve.

Today, people are accustomed to viewing motion pictures with sound, and the absence of it, especially with those unitiated in the hobby of amateur movies, is decidedly noticeable. Such music, however, must be carefully selected. It must be appropriate for and in harmony with the film for which it is selected. We had the pleasure of screening Raymond Korst's "Animal Antics" which features the trick photography described in the June, 1944, issue of Home Movies, and the recordings we selected to background this film were a perfect match for this picture. Particularly did they complement the rhythm of action where animals in the zoo were seen swaying back and forth. In another instance, we found a record that included the crow of a rooster which harmonized perfectly with a sunrise scene in Al Richter's "Lake Tahoe." Our club members were particularly interested in the superb home processing demonstrated in the finish of films loaned us by Raymond Korst of Buffalo, New York, and Tom Costley of our own club. These projected with all the clarity and brilliance of the best factoryprocessed films. The programs of films and their contributors were as follows: "Freckles Herself," by Ralph Richards, San Jose, Calif. "What Price Victory," by Jesse W. Richardson, San Francisco. "Lake Tahoe," by A. W. E. Richter, San Jose, Calif.
