I have a super graphic board that I just bought (the fellow had removed a 105 Xenar from the lens). The measurement doesn't seem to be a Copal 0. Could someone help me determine which lenses/shutters may fit in a decent portrait length?

Thanks

my Xenar is in a #0 shutter about 32.5mm Threads
but the hole in the Board is like 36mm

now a Symmar-S 5.6/300mm is in a #3 shutter it has 62mm threads

I think that you mite find some thing in a tele-lens in a #0
but the longest that I have is a tele-lens is a 240mm its in #1
but all of my other long lens are in #1 or #3 shutters

Boards can be rebored with a larger hole. Get the lens you want, then have the board rebored to accept it.

I have boards drilled by www.skgrimes.com . There are other machine shops that will do the work.

I have an empty board with the mechanical linkage to the electronic shutter tripper. I can't imagine you can just drill the hole bigger due to what appears to be reinforcement structure around the existing hole. It looks like this is due to the two layers of the board. While I know that I canter by with a plain graphic board, I am looking to utilize the features of the camera including the body release, flash connections and release.

Another option for portraiture with a Graphic is to use a roll film back and the "normal" 135 lens.

I understand the potential issue with boring a larger hole in a Super Graphic board... interference with the internal shutter release linkage and flash connections. This is really only a probelm is one is using the solenoid release and the electrical connections on the body. I use both and have wondered same question but have never (a) found an internal diagram of how the sandwiched SuperGraphic board is constructed or (b) had a spare bard to dissect to find out.

The "Sandwiched" lens board for the Super series Graphics is nothing more than the standard pressed aluminum Pacemaker board with large bumps on the sides for the board locks and a plastic plate attached to the rear to make the release mechanism light tight.
The Super Speed 1000 board is an integral part of the shutter.
The release is a rigid pin in a guide, a catch that fits into a notch at the board base for the solenoid to engage and connected to the shutter trip lever at the top.

45PSS,

I have the regular sandwiched board, and also a 1000 shutter 135mm lens on the "custom " board.

Your comments made me take another look at the sandwiched board. I took it apart and I see now how it all works - it seems possible to make something that could work....

Thanks
