Want to Buy WTB Sinar Norma 52mm lensboard

[andreios]

Hi all, just giving it a try before I "damage" (e.g. attempt drilling) one of my spare lensboards with smaller holes - I need a Norma lensboard with 52mm hole for Synchro Compur shutter on my newly bought 121mm SA.
Thanks.

If you make a mess of it, I have an undrilled Sinar board sitting here (I assume they are all the same at 139mm x 139mm) - Should be able to cut a hole to what ever size you need.

Are you sure it requires a 52mm Dia hole ?
According to SK Grimes, a Compur #2 mounting hole should be 52.5mm Dia.

Hi Paul, I will let you know how it went..
As for the size - i measured the retaining ring with a caliper and it was 52mm. Somewhere else i have also found the size as 51.7.. Anyway, it is always safer to cut smaller first...
