Ball Bearing Shutter

[Downix]

I recently aquired an old Kodak ball bearing shutter w/ lens (incredibly sharp lens I found) but the bearings in it are worn out. I cannot find, however, what size it used, and the original bearings are worn to the point that I cannot be sure. Does someone know what size of bearings were used in the EKC ball bearing shutter?

Not sure just how small they are, but you might try taking one of the bearings into a decent bike shop - they're used to looking at very worn bearings and figuring out what size they once were so they can supply replacements.

Ball bearing shutters were made in several sizes. The suggestion to go to a bike shop is a good one.

Ok, determined it uses 1/16" bearings. I hope this is all that's needed to get this working, but if not, no biggie, as the shutter seems a pretty simple design.

I have one of those that I opened up and promptly bumped it off the table and lost the ball bearings to the carpet forever.

I guessed and substituted very small size steel shot from an opened up shotgun shell and it works like a charm. I got lucky ;)

I think they only came in one, maybe two sizes. Lots of them available on $bay. I try to snag one now and then if it's got a Rapid Rectlinear in it. Very simple shutter. No escapement, just variable tension on a spring or two, depending on if it's the 2 or 3 speed model. Rarely very accurate.

I don't care about accuracy, as I use it on B setting almost exclusively.
