I recently bought an Ilford Sprite 35 for £5 with a non-working take-up spool. I liked the style, simplicity and the price also meant this would be a good starting point for myself to learn about camera repair. Its carcass is held in place by the rewind knob and with the only two visible small screws. It is worth remembering that this camera was sold as a cheap 35mm camera and age has turned the plastic brittle, unforgiving when you separate the two plastic parts.
A broken plastic lug on top of the take-up spool was the problem here. I cleaned the camera and also the simple fixed focus F8 plastic lens with a pec pad. The old grease was cleaned up around the top of the spool which had solidified. I very sparingly lubricated and reassembled the gears and then glued the lug back into place. I am sure if I had glued it before assemble it would have snapped again. Once the glue had cured I placed a small rubber tube between them. It does not seem to hold the gears in place as you would expect but the shape is important. Without a circle the gears slip as if on a cam. The small toggle was also cleaned that is used for selecting between the available apertures of F11 and F16. To put the camera back together its best to hold it at a slight downward angle. With the lens assemble sitting in its pocked on the case rather than the carcass.
I am looking forward to shooting a film through this little camera, when I do the photographs will be posted below.
