DIY 240mm f9 G Claron shutter scales

[Lachlan 717]

As requested by a few Members, please find the scales attached.

I'm happy to leave these scales off the lens for the next day or two in case the scans are not to your liking and/or you require something else.

Hope that they help!

You need to add what size shutter the scales are for, I assume it's a Copal #1.

I've drawn up a scale for an early rimset Compur #1 shutter, I did this a few years ago for someone on either this foum or APUG, I can't remember what FL though. It's relatively easy to modify for other FLs though. Late Compurs have a linear scale like the Copals. I'll try and find it as I need to make some scales myself.

I don't have a 240mm f9 G Claron but it is very nice of you to post this!!!

Thanks, JMoore.

I'd love to see a repository of these on here.

Thanks mate, will whip out the tape measure and see if my copal index is spaced the same. If so, the work around is as easy as determining the f9 and taking 2-3-3-etc increments from there. Seems to be the same for the 150.

Good evening Lachlan,

Thanks a lot for this! Just had a bit of a look at my copal scales, distances are identical. I've now popped the cells in an older copal 1 and it is as easy as 5.6 = 9, than 2-3-3-3-3-3-3 increments to 90 (which is 45 - 1/3 on the copal scale). Will try to shoot a few sheets of film over the weekend to see how they turn out.

mine does not have a linear scale...

That's what I'd assumed it's only the very late Compurs with the scale on the side have equally space f stops. What FL & size is yours ?
