Cambo TWR 54 - 4x5 Twin Lens Reflex (like Gowlandflex) Question...

**Aesthetique** · 26-Mar-2018, 07:17

When I bought my TWR it came with a strange sliding rollfilm back, I think for taking mugshots. At the time there was no info on the net about what I should have down there for 5x4, so I fabricated something out of cardboard as a template. Fortunately I knew someone who could get aluminium lasercut and I had the plate made that slides into the slot. This cut plate, aluminium block and second plate, a couple of bolts, some felt as a light-trap, neoprene foam as a tensioner and I have good grafmatic holder.

Not bad! The original uses a spring clamp, which is probably about as secure as your setup.

This is incredibly secure....With the bolts locked tight, I can hold the entire camera by the loop on the grafmatic! When I started to work on the camera again, I still had round headed allen bolts. Until I could find the key for them, I could not get the grafmatic back out, it was locked so securely.

It is only designed to take a grafmatic though.....

Nicely done! Grafmatics are the way to go in general, I think. I like them a lot. Can you fit a Fuji PA-45 or PA-145 back in there? (Polaroid 550 or 405)

I did have a fuji quick change back, but never used it....no idea where it is now. So unfortunately not in a position to answer that question.... But assuming it is the same thickness as a grafmatic, then it would.... if it is thinner then another sheet of neoprene would have to be put in to ensure enough compression.

They are a bit thicker than the grafmatic. The spring back on my Speed would take a grafmatic but not a Polaroid 405.

yeah, PA-45 and -145 are a bit thicker than Grafmatics, agreed.

A Fuji Quick Changer 45 is the same thickness as a Grafmatic, and is better built. A Fuji Quick Change holds film pre-loaded in cartridges. It is possible to reload film into the cartridges.

I have studied, taken measurements, calculated paralax correction angle and drawn a 210mm cam with EdSawyer-style close focusing. Converted it to a dxf vector and have got a company specialising in laser cutting metal to quote me prices for aluminium and they are coming back to me with the price in brass. If there is any demand I can make more.....
