Hello! New to the forum, hoping to get some help! Recently purchased my first 8mm projector, a Bolex Paillard M8. Tried it for the first time the other night, and the film was running a little slow. I started to turn the speed control knob, and the knob immediately came loose and I heard a piece rattle around inside the machine.

When I took it apart, I saw that a bottom part of the knob had snapped off, which released a spring and some kind of brass-looking rod or lever of some kind. I can super glue the knob back together, and can obviously figure out where the spring fits, but does anyone know where in the world the brass rod/lever is supposed to go? I've tried to get some specs online, but can only find the basic manual that came with the machine.

I've attached pics of the issue...hopefully one of the 8mm pros out there can help!

Thanks!

Going from memory here. The rod spans across those two wire wound posts. The thinner part of the rod, in the center, goes onto the knob. The spring goes over the knob and puts pressure on the rod. When you turn the knob to control the speed, the rod slides along the wire windings, up one side and down the other. Looking at the windings, you can clearly see where the rod has moved along them as there will be no corrosion there.

Make sure the rounded side of the rod, not the double edged side, rests against the wire windings.
