Hi all, the motor of my EBM is gone, so i was thinking to replace it with a faster new one to achieve higher speed than 50 fps of the original one. The question is : how higher speed can run a Bolex without damage mechanics ? For my purpose 100 fps is the goal.
Thanks in advance

I wouldn't try to get a bolex much past 50. They use super light-weight gears and there are lots of them. When they choose the 50FPS speed, they did it for a very specific reason and I'd be concerned about long-term damage. Not saying it's impossible, just saying why risk it?

Hello Tyler thanks for reply, well, the only gears that risk damage ( to me) is the pulldown claw mechanism. The others gears could run indefinitely at  faster speed than 100 fps, untill they are correctly lubricated. Anyway, i was curious to know if anyone has tried it before with an external motor for example.
