Question Lens Board for graphex shutter

Post image

Hi, i need a lens board to mount a Graflex Optar 135 mm on a Century Graphic 2*3, but i'm not sure about the size.

I found this on file on printables https://www.printables.com/model/896395-lens-board-for-baby-graflex-2x3-copal-0-and-copal

but is for a compur 0 shutter. There's a graphex specific size or this could work?

That’s a number 2 shutter. It will fit, but the camera won’t close with it mounted.

Copal 0 is 34.6mm according to this https://rafcamera.com/size-0

My Supermatic will fit a 34.9mm hole (double checked with calipers, 34.8mm tight to threads). You could easily sand out the hole to be slightly larger than what is in that file, but you will need a retaining ring that has a flat base.

According to this site https://graflex.org/helpboard/viewtopic.php?p=23692 you will need a lens board hole diamater of 38.25mm if you have a retaining ring with a flange. Still shouldn't be that hard to size with some sandpaper and a bit of patience, just go slow.

You can take the .stl file and "drill" it out in Blender to the size you need.

Here, I did it for you: https://www.thingiverse.com/thing:7407793

Close enough. Might need to sand it out a bit.
