Lens board for Graphex Shutter?

[Raul Oscar Arteaga]

I own a Graflex Optar lens in Graphex shutter. I need to get a lensboard for a Calumet 4x5 suitable with this shutter, but it is never advertised. Its diamete r is approx. 42mm. Is there any equivalent in popular shutters?

Thanks in advance for any help on this matter.

Raul: Check with Midwest Camera Exchange (MPX). They have a web site, and they are a good source for lensboards, etc. I think you can either build or have built a decent lens board for the Calumet. Try either aluminum or the thin plywood you can buy in model airplane hobby hobby shops.
