This lensboard looks 3D printed. Ask your local 3D printing service. There are free models of a Graflex lensboards available which you or they could edit accordingly. Here is an example http://www.thingiverse.com/thing:797723

That's one option. To put the problem in standard language, the rear of the lens is too large to pass through the front standard.

Several solutions in addition to a "top hat" lens board:

Cup-shaped adapter threaded female at the front to accept the lens, male at the rear to accept a retaining ring. Lens plus adapter mount on the lens board in the usual way.

Stepped bushing, threaded male at the front to screw into the rear of the lens' barrel and male at the rear to accept a retaining ring. This is possible only if the rear of the lens' barrel is threaded internally. The bushing mounts on the lens board in the usual way, the lens screws on to the adapter.

SKGrimes has made both types of adapter for me so that I could use lenses that couldn't otherwise be mounted on my 2x3 Speed Graphic.

The lens shown in the link is in a focusing helical. What's in a focusing helical can be removed from it. I think, could be mistaken, that once the lens is out of its helical it can be mounted on a Graphic board and will go right on the camera with no more work needed. I think. If the OP's Speed Graphic is a 4x5er.

Just curious how are the files/templates opened? I followed the link and downloaded the files, but could not open them (in win7)

Tony, the usual method would be to use a CAD 3D Software Program.
But, if all you want to do is to view the 3D Model... Then you can just use a STL Viewer.

Thanks everyone, the top hat board looks interesting. In the meantime, I'll keep my eyes open for an anniversary speed graphic.

Sorry for double posting, won't happen again :)
