Hi all!

I'm about to design and build an 8x10 camera. I have most of the design ready but I have one problem. The moving and screwing parts. Bolts, nuts, knobs, focusing knob / thread, etc. Those you see in all view and field cameras...

I know most of the camera makers manufacture their own pieces, but I think there must be somewhere I can find similar or the same components for sale as units or bulk.

Does anybody know anything about this? Any help/advice?

Thanks a lot!!!!
