Convert speed graflex to 1/1000 universal shutter with 3D printing

Graflex Speed Graphic is the best way if you want to use high speed portrait barrel lens. But it's quiet hard to find 5x7 or 8x10 speed graflex. Usually you should cut it into half and make mount for both sides to convert it into a universal shutter. Now with 3D printing technology you can make this conversion reversiable and more robust.


here is the link to 3D printing file. It's for 24 speed Graflex Speed Graphic only, since there's no shutter release connector on the panel of 8 speed models

hi rayfor
sorry for my ignorance but what is a 24 speed graflex ?
I've been using graphic and graflex cameras for a long time
but have no idea what a 24 is ...

Excellent modification and craftsmanship.

Nomenclature misunderstandings aside, I am not clear as to what has been done.

Please post a narrative description of this project.

He is using the roller shutter as a big shutter

It will fail quickly if somebody keeps testing the 1/1000 speed

Cut it in half = split the shutter from the rest of the Speed Graphic to mount on a view camera. This 3D piece accepts the mechanics of the Speed Graphic FP shutter, and one end attaches to the camera and the other end accepts the ground glass back.

Very nice!

There are two type of graflex speed graphic shutter, early model with 24 different speeds and later model with 8 different
speeds.

I'm just providing an easier way to convert a graflex speed graphic to a big sinar mount shutter. Consider a sinar DB shutter with 1/1000 speed and bigger hole. This is a common way to use big barrel lens with modern high speed film.

thanks! I didn't know they were referred to as graflex 24 and graflex 8 shutters, makes perfect sense.

Then ks for the clear explanations of this project. I had once thought to simply cut off the front of pre-anniversary Speed and graft the shutter portion onto a a wooden piece that would replace the standard GG back on a 4x5. Tihis is a more sophisticated approach and well done.

Wish something like that could be done for an 8x10. Folmer and Schwing did make 8x10 roller blind shutters very early in the 20th Century, but not many, I think.

In the last 40 years, I have seen one such shutter "in person" at a collector's meeting and one other on e-Bay.

so impressing！！！！

Here is my primitive, yet functional adaptation of a Pacemaker Speed Graphic carcass to "Big Blue", my B&J 5x7 Rembrandt portrait camera.

Interesting!
I like the "Big Blue" too! Quite inspiring for me, I have B&J 5x7 Commercial in the classic grey color and thinking about stripping it off.

Thanks!
"Big Blue" had been painted an ugly olive drab at some point, and was beat-up beyond refinishing...so I gave it a fun facelift. Less threatening for portrait sitters, too.
