Hello all,
I'm new here so, thanks to everyone involved in allowing me to be here. I believe I am the friend referred to in the post by G. Tveden. I'm converting some reels of super 8 film to digital and the B&H 357Z projector's fixed frame rate @ 18fps doesn't match that of digital camcorders, which I believe is 29.97fps creating "flicker" in the digitized image. From what I've read in order to remove the "flicker" the frame rates have to be adjusted to match. I have also read that reducing the frame rate to 15fps will also stop the "flicker". In order to test whether or not that is valid I set up my homemade telecine box and while running the projector, pinched the ratchet sprocket between my thumb and forefinger, slowing the projector and the "flicker" disappeared.
So, what I'm hoping is that there is someone here with knowledge of the motors used in Bell and Howell projectors. I see in a previous post to a response about the speed control on the 466A, it was stated that the control is by mechanical means only. But I see from the images in this thread that there is an electrical adjustment knob as well as a mechanical switch. So, I would conclude that while the slow motion is controlled mechanically there is a rheostat that controls the speed.
So, what I guess I would like to ascertain is if anyone knows whether the motor used in the 466A and the 357Z are the same or similar in that they can both be controlled by a rheostat or some other type of electrical means.
If it can't be done electronically, cheaply and reliably, I'll reduce the speed by changing the drive pullies.
Thanks,
JC
