Has anyone ever experienced a camera jam or any adverse effects while changing the frame rate in a Bolex from 24 fps to 48 fps while the camera is rolling?

Mechanically it works... I do it all the time, but run some tests becase the exposure will change slightly (or a lot).

It changes predictable amounts, actually. Changing from 24 to 48 fps will half the shutter speed, so he'll have to open up a stop while he ramps.

I've never had mechanical problems changing frame rates on a running Bolex, but you might get some camera jiggle if the dial doesn't move fluidly when you turn it.

Or like many filmmakers did in the sixties, change the frame rate and let the exposure change for effect.
