RB67 Dark Slide Question

[Paul Ron]

Erie, I made an adaptor recently using a #1 extention tube. I rigged it so I can use the jam ring as my cocking mechanism. The tube neatly screwed onto the lens board using the screws at the rear of the tube. Drilled corresponding holes in the lens board and just through screwing it on.

When using the RB lens on hte 4x5 all you need to do is cock the lens using the jam ring, use the lens in mirror up. Now with the lens wide open you cna focus. Advance the jam ring to the point where the lens closes down n trips the shutter into mirror up wait state, insert film n fire the shutter via cable.

I never got to shoot with it since the guy I made it for is in Canada, he beat me out of the adaptor with out paying me. I asked him many times to show me the pictures but he hasn't replied. I may just make another for the hell of it.
