Help with NPR motor switches and loop noise maker
Posted 23 August 2009 - 03:42 PM
The motor that came with my NPR had the back button broken off (see picture). I need someone to explain if I got the switches right for the NPR so it is at 24 crystal. I assumed that I set the 2 so they are at the 60 mark and the other at 24. What does the switch which says Int/Ext do, I thought it might switch between the crystal and the tachometer.
There is a small gauge on the top of the motor that goes from 12.5 to 40. I am assuming the button that broke off controls this speed.
Could someone please verify/explain the motor buttons to me.
Also when I loaded a dummy roll of 200 feet on a core, I can't seem to get the noise maker to stop going off. I loaded it about 20 times and know I am leaving enough loops. I tried bigger loops too just in case.
The problem is that every time I start the camera, I can see the lower loop instantly get pulled tight and start the lower noise maker. I tried giving all the loop to the lower and it still is pulled tight right away.
What could be wrong if the lower loop goes away right away every time?
I know I need to get this camera serviced by a professional, but I wanted to make sure it wasn't something I was doing wrong.

I think you're losing the film loop because of the camera movement needing adjustment. It's probably the clawstroke.

I plan on using these cameras for the rest of my life so I am not in a great hurry to fix up the NPR. Ultimately I want a video tap and super 16 so I might wait until I have to funds to get the rig together.
Your knowledge and the help of everyone on this site has made it possible for me to shoot on eclair for which I am very grateful.
