Hi Mike,
Bolex cameras are relatively simple to dismantle, clean and put back together. As most of these little boxes are clockwork, all you need to do is remove the film gate plate first then it is a number of small screws. The most difficult part replacing the film transport pin assembly spring and the cover particularly the spring that keeps the tension on the feeder reel. (these are far from accurate terms I am using) By now you are probably saying what the?? If you are serious in cleaning and re lubing your bolex, send me a private message and I can walk you through it. I have managed to rejuvenate three bolexs. Their yvar/swittar lenses are very crisp, especially with 100d film. when lubed and running smoothly, they purrrrr.
