Thanks for posting an instructional video.

Always interesting to see who we are.

Piggybacking off of this thread because I think its relevant.

I have my Schneider 180mm MC on a lens board I bought off ebay, I believe it's made out of plywood. Now - I don't know if this is something I did,

but everything I move the aperture, the bottom scale has a piece of metal which scrapes, and gouges out the lens board. Once it gets past f11 or so it stops, and requires a real tug to move. Is this

a mechanism of the board, or did I somehow put it on wrong?

Hi Greg,

A reasonable idea, but I think combining enlarging lenses and taking lenses in one video is a fatal flaw.

You might re-do it, splitting it into two videos, one for each subject.

You want to put a thin a spacer between the back of the shutter and the board. Use a compass, mark a set of concentric circles on a piece of paper, cut and try. You may need a couple of rings to get the distance needed.

Thank you for the reply Dan.

Just so I understand, the spacer itself can be made out of paper? I'm assuming I would want to use a thicker type of paper then?

Yes, paper. I'd steal a sheet of 20# from my printer. You don't want paper that will compress much.

Nothing personal, but my common complaint about you tube is way too much chatter. The maker's contribution should be evinced by hard tech, DIY, not personality air time.

Many modern lens-shutters also have a screw on the back near the retaining ring matching a hole in the lensboard to prevent rotation. Some people discard this screw, but I drill a hole in the lensboard to accommodate this screw. What is your opinion on whether or not to use the antirotation screw?
