HOME MOVIES FOR AUGUST back to where the fade started. The magazine is again turned over to its original position and a fade-in made resulting in a lap-dissolve of the two scenes. Without a frame counter, this process could not be done accurately, but with a frame counter it is only a matter of simple arithmetic to determine the correct number of frames to run off both for the fade out, the wind-back, and the fade in. Using this feature along with other gadgets which the amateur might devise, accurate wipes, timed fades, etc., may be made. The addition of single frame release and frame counter to the Perfex camera is comparatively simple. A piece of string, a little glue, a screw driver and a pair of pliers are all the implements required. The only machine work necessary will be in making the new cam. This can be made by a machine shop at very little cost. However, if one has mechanical ingenuity, a small piece of steel and rod is all that is necessary to enable one to make the cam himself. The exact dimensions of this new cam will not be given here as the one removed from the camera will serve as a guide and template for the new cam and shaft. For ease in making the modification, step-by-step pictures and instructions for each step are given here. First, make sure the camera spring is completely unwound by pressing the control lever until the motor stops'. This is most important! All spring tension on the motor spring must be released before taking camera apart. In taking the camera apart, and in reassembling it, consult the accompanying pictures, following these closely along with the directions given for each picture: Picture i — After having made sure camera spring is unwound, remove winding key by turning it counterclock-wise. Remove screws A, B, C, and D. Remove speed dial and viewfinder dial, being careful not to lose the square tension spring under the view-finder dial. Picture i — Open camera and remove screw E, and F. Watch for coil spring under footage dial. Picture 3 — Remove screws G, and H, and remove the door assembly. Picture 4 — Remove screw J, then turn camera up. To the left, on top of the case, remove the screw beside the handle strap. When this is done, the case will be loose and will slide free from front of camera. Picture 6 — Remove screws K, L, M, and N from brass plate. Again check to be sure that the camera motor is completely unwound. Remove the plate. Picture 7 — Lift out gear P, and governor Q, cam and shaft R, and spring housing S. Wipe surface of the spring housing drum clean, then cut out numbered strip below. This numbered strip should be cemented or glued onto the spring housing, as shown in picture 5, and fastened with a rubber band or cord until the glue or cement has set. Duco household cement, liquid solder, or other such paper or fabric-to-metal cement is ideal for this purpose. Remove the cam and shaft R, and have a new shaft and cam made as per Fig. 9. This can be done by tracing around the old cam and adding a "C" shaped piece on the side. (See Fig. 8. Arrow points to cam.) Allow enough clearance so that the pin on the shutter shaft (Fig. 8), will pass through sideways and down. This new cam should have the same thickness as the old one. It should be notched out at A, and B, (Fig. 9), so that the cam travel is great enough to allow the pin to pass through the opening. Place the control lever and screw A as in picture 1 in the shaft and check the single frame release operation by hand. By turning the shutter shaft by hand and pushing the control lever half way down, the shutter shaft should revolve one revolution and come to rest against top of cam. By pushing control lever way down, the shutter shaft should revolve continuously. Next, reassemble the camera in reverse order back to condition shown in picture 6. This will amount to having the spring housing S, the governor Q, the new cam and shaft R, and the gear P, along with the brass plate in place and fastened. Incidently, there is a pawl and spring on the back of this brass plate. The pawl must be pushed down between the gear and spring before the screws K, L, M, and N, can be tightened. After the glue, cementing numbered strip to spring housing drum, has set firmly, the rubber band or string holding the numbered strip in place may be removed. Before final steps in assembling, install the key and control lever to make sure that everything is running free and correctly. Then, by placing the camera case beside the assembled mechanism and looking at the latter from • Continual on Page ]ji • Fig. 8 — Only part that must be replaced is cam on shutter shaft which must be altered to provide the single frame action. This is a comparatively easy task. Cam as removed from camera. . .
