Maybe a silly question - but is there a tool one can buy to tighten the screw at the rear of the lensboard.

By hand tightening I don't get enough bite - lens is a bit loose in the board hole....

I think this is what you are asking for

from Toyo simple basic design that works on most modern lenses/shutters without too much risk of slipping and scrathching the lens/glass or the board.

ps - the first two are especially useful because they are small and flat and credit card sized - easy to keep in a camera bag for when you find the shutter has mysteriously loosened in the board while on some long trip somewhere...

The Linos (formerly Rodenstock) lens wrench does 0, 1 and 3 size shutters from Copal, Compur and Prontor. I believe the Toyo only does 0 and 1 size shutters and may not have the proper pin size for all 3 shutter types.

If you don't have a spanner you can get it pretty tight (providing no pin on shutter) by putting your thumb on the lock ring and turning the shutter instead of the ring.

I've used the flat kind (Rodenstock I think) and the one made by S.K. Grimes. I prefer the one made by Grimes because it's almost infinitely adjustable, which can be handy when working with older lenses and odd shutter sizes. It's a little expensive ($30) but as long as you don't carry it in your backpack while boarding an airplane it will last a lifetime. The first one I owned was confiscated by airport security at a time when their policy was to confiscate all "tools." Not sure they'd do that today but to be safe I'd put it in a suitcase.

TRY THIS:
Hold the retaining ring with one hand (or a few fingers) and rotate the shutter with the other hand - this method will get it at LEAST as tight as any wrench could. I promise.

It's good to have the cells out when you do this.
