Frame spacing is a function of the camera mechanism, the motor drive plays no part in this. Your test films will show similar faults. Remove the emulsion from a cheap film. Load into camera and without closing camera back, advance and operate shutter a good few times. Apply pressure on the sprockets and take-up spool with finger and thumb whilst doing this, also mark position of the film gate's vertical edges for each frame. You should be able to detect any slippage/damaged gears in wind mechanism by doing the above. You should also listen for the point when the shutter fully cocks and when wind-on locks. You will have to examine the complete wind/cocking mechanism to pin-point the exact fault. |
