Tool to remove flange ring

[Bob Salomon]

OK. Never heard of Quioptiq. Sounds Chinese.

No, German.

The spanners from SK Grimes are very good:

I've pulled some awfully stuck pieces apart with these. The pointed ones can work on very small items.

Scratch one lens with an inferior product and these would have paid for themselves.

I don't use spanner most of time, although I have them. I just twist the shutter body from the front. Does not work if there is an indexing pin sticking out the back of the shutter body into the lens board! To tighten, just turn shutter to tighten, with thumb on lockring on back to provide friction.

Take a bench vise (skruvstäd) and clamp a pair of screwdrivers (skruvmejslar) pointing up (upp). It takes a little care to turn the lensboard evenly while keeping it flat, but the spacing and standoff are highly adjustable.

I simply use a pair of bent-nose needle-nose pliers, having ground the tips to proper dimension with a bench grinder. Seems to work at least as well as any mail-order dedicated spanner.

I prefer a good set of vice grips or a small cold chisel and a 2 oz. ball peen hammer. Works most of the time!
