What's needed to make this 4x5 Graflex RB complete?

[campy51]

What kind of back is needed to make this usable? Can it be converted to Grafloc back without jumping through hoops?

 

[campy51]

I think I found my answer. It appears I just need a film holder made for this model. Forgot about it being an slr and no need for ground glass focusing.

What you have there is a Graflex back; standard film holders are for the Graphic back (aka spring back) and won't fit that one. Wood film holders can be converted if you have wood shop tools, or you can usually find a few Graflex back compatible film holders, bag mags, even sometimes a Grafmatic on eBay.

I bought one of those Graflexs from a retired Graflex and Graphic repair man who converted it for me to take a Graflox back as part of the purchase.

Take it from me, compatible double-sided film holders are not easy to find now days, but bag mags with up to 12 shots are fairly cheap.

@Graflex Garage (a user here) rebuilds them for a very reasonable price; replacing the leather and light seals.

I have been advertising and searching for double-sided Graflex film holders for over 6 months; no luck.

Based on what I've seen from Ari Jaaksi (YouTube channel "Shoot on Film") all that's needed to convert a wood Graphic film holder to Graflex is to make a compatible groove where the registration rib is, and cut grooves in both long edges to accept the Graflex lock slide. This is probably also possible with plastic Graphic type 4x5 holders, but I haven't seen it done so I can't say for sure.

Thanks Donald, I was wondering if that was the case myself. Tried tracking down a video of his that addresses this modification, but was unsuccessful. Maybe it is mentioned in one of his many long videos on Graflex cameras.

Look for the video where it details repairs to his RB Series D. Pretty sure that's where he talks about converting the film holders. It may also be in the Series B videos, try about 4:45 in this one:

in a similar vein, I converted an RH-8 roll holder to work on 6x9 RB Graflex, a long time ago. It involves cutting a groove where there may be a ridge. Easiest to do with a milling machine. I went a little deep and got into the dark slide channel, but I just put a piece of tape in there and used it for years-- somehow the dark slide never hit the tape, and the tape seal was 'good enough'.

If you look around long enough, you may also find a film pack adapter for Graflex-not-Graphic back that can be modified to be useful for something. I think some people turn those into plate holders for wet or dry plates, too.

A problem with looking for these holders is that most people don't understand the difference between the types of backs, and thus they are unlikely to be listed accurately.

Thanks! Good to know.

I have a film pack adapter that came with the camera. I had not thought of the dry plate angle and was thinking it would be a curiosity or makeshift GG holder; thanks!

Yeah, that's why I spent an hour or two, plowing through listings on Ebay, looking at the photos carefully. None of the listed Graflex/Graphic film holders were slotted...

Bummer...

PS. Here's a photo of the photographer who owned the camera before me. Guess he shot a lot of sports. Too bad the telephoto lens wasn't present with the camera, but the normal lens is in great shape...

There’s several Graflex back cut film magazines “bag mags” available. They will most likely need new leather bags made and fitted, but the advantage there is you have 12 sheets in the same size and weight as two double sided holders.

I have five of them for my 3x4 Graflex, they’re quite nice

Just had one of those rebuilt by Graflex Garage but have not had the opportunity to shoot with it.

I need to play with it a bit more; it kinda freaks me out a bit. Seems abnormal to operate!

I have a few 4x5 graflex holders and a few bag mags for my RBGraflex. I can check how the holders compare to normal plastic holder. I don't think the plastic would withstand having a groove cut.

@Kino gives good advice about the bag mags. Even though mine work, the leather is degraded and covers the film with flecks of crap. Good idea to replace it. Those things are pretty fool-proof, if not all rusted up.

There actually was a 4x5 Grafmatic model for the Graflex back, as well as the more common one that fits a Graphic (under the spring panel) or Graflok. I want to say it's the 1124 vs. the Graphic/Graflok 1125, but I could have that wrong (and I'm not at home where I can look at my Graflok 4x5 Grafmatics). It's only six sheets instead of twelve, but IMO faster and easier to operate (might be easier to load, too; I haven't ever handled a bag mag). The septums in both 4x5 models are the same, AFAIK, so replacements shouldn't be a major issue, and I've had good results so far with straightening slightly bent septums.

Hi,
The format back of that camera does not look quite right in the picture for a 4x5, are you sure its 4x5 and not 3 1/4 x 4 1/4?

On looking back at the first picture, I agree -- Series C instead of D?

I thought about buying it for $150 and stripping it down to bare wood, but I have never done a project like that before. Will I be in over my head?
