Hello,
I recenly bought a knew 135mm Wide Field Ektar in a Supermatic shutter. I was wondering if anyone knew what size lens-board opening - copal- I would need to adequately secure this lens? I am using a Linhof III Technika and will have to buy a new lens board for it.
Thanks so much for your help!
From your Canadian friend,

You will need a blank board and to cut the hole to size.
BTW the mounting holes for Copals are as follows (from skgrimes.com)
0: 34.6mm 1: 41.6 3: 65 3s: 64.1.
I think a Copal 0 sized hole should work...
Hi Lisa,
Check with K.E.H., in Atlanta, GA. (www.keh.com). They have several previously owned Linhof Tech. lensboards listed on their website. A call will verify if one of them will fit your shutter. They also have a blank one listed in case you need a special size. K.E.H. ships internationally.
Not the answer to your question, but here are all the hole sizes for all shutters out there - I have bookmarked this page (it's actually from this forum) and use it all the time: http://www.largeformatphotography.info/lensboard_hole_sizes.html

Very cool link, Juergen. Alas the Supermatics are missing.
Lisa, it isn't a new lens and Supermatics don't conform to the Prontor/Compur/Copal ... sizes. Get a board, send it and lens to a craftsman such as www.skgrimes.com
A lot depends on whether your boards are wood or metal. As Ralph said in the link, there are options: for metal boards, your local machine shop is your friend. Just tell them how big to make the hole (give about .010" for clearance). For the wooden boards that I use (Wisner), I find an undersize hole saw and whittling usually suffice.
i have a 127 ektar in a supermatic shutter. it needs a hole in the lens board that is just bigger than a copal 0 opening. i bought a lens board with a copal 0 opening and then sanded (and cleaned thouroughly) the opening to the size i needed.
it ain't a glamorous solution, but it seemed to work for me.
