I revised my EL/M mod. The little pawl holding the winding gear kept breaking so I put the winding knob on a one-way bearing. I also added a proper shutter release button scavenged from a 35mm camera. It locks by a 1/4 turn.

This is such a great solution for broken electric Hasselblads! You printed this shaft that will connect to the holes in the sprocket to manually wind an EL(/M)... Do you have a page documenting this? Would you share the models for the 3D-printed parts?

Here is a guide for my previous build with the problematic pawl. https://www.thingiverse.com/thing:6314205

I'm using an EWC1209 bearing if anybody is interested in remixing the (---remixed) design.

Horseman Convertible that was ‘converted’ into a wide camera by replacing the broken 62mm lens with a 47mm f/5.6 Super Angulon mounted in a focusing helical.

For the finder, I removed the (MASSIVE) paralex correction base to shorten the Mamiya 50mm finder that is perfect in both function and function for this camera. The finder has a large bright image that is easy to see, even if you wear glasses and has both 6x7 and 6x9 frame lines.

I just love industrial chic look and the function of the cameras.

that's a very nice piece of camera that you made there again. I like your approach! I was also wondering, this 62mm lens you took off, do you still have it ? and did it happen to have a clear back lens? if so,I might be interested. ( is it allowed to ask?) there is a horseman on the web with a hazy back lens and I might give it a try

it is too much fun to knutsel! (dutch for 'to craft').

is the focusing helical custom made? or taken from another lens?

beautiful execution, Dirk!

It's a 10-15.5mm M42 to M42 focusing adapter intended to be a macro adapter. The focus is infinity at full lock on one end and to get to 20 and 12 feet are such a tiny turn. I still haven't figured out how to index it!

Really cool! So, you used a Mamiya Press 6x9 back and just added a cone and lens to it. It’s pretty much the idea I want to execute for my 6x12.

Looks really well-made!

and there is a flowerpot and a helicoid involved.. that's about it...

You may want to adapt a "match the marks" type system - similar that used for scales of a Crown Graphic.

I didn’t expect a flowerpot to be involved!

Cheap Chinese helicoids are easy to get on AliExpress or Amazon these days. I’ve bought some of them last month, a 52mm and two 58mm’s.

Some other parts are on their way to me. I hope I can get them going this summer, so I finally have something to show here.

This project came to me in pieces from the estate sale of a machinist/photographer/experimenter.
He had cobbled together a body to connect a 65mm Super Angulon to a Hasselblad back.
I sold the Super Angulon, and thought the body would make a good pinhole camera, since it had no focusing mechanism.
A junk shutter showed up with only the blade arrestor working....a pinhole was added...and bada-bing!
I present to you..."HassHole".

This is more correctly known as a vernier scale. It can be used to measure very small differences without eyestrain.

Plaubel Makina ground glass holder, modified with custom-made 3D printed adapter to mount the Linhof Einstell-Meßbalgen (focusing bellows) for 6x9 cameras.
Glued together using contact cement, and fixed in place using M2.5 hobby shop nuts and bolts.
Works perfectly on my Plaubel Peco Jr 6x9 view camera rear standard.

my latest project, a 6x9 75mm 'press/polaroid'
Click to expand...

Super cool project, love the flower pot. I‘m always looking for weird items, pots, bowls, mini loaf pans (perfect to add to the front of an old Stereo Realist) etc,. I’ll have to start paying more attention in the flower section of Home Depot and Menards!

I’ve always wondered about this Mamiya film back and it is was possible to modify into either a 6x12 or 6x17 back. I remember Dean Jones (the Razzle, 4x5 Polaroid conversion guy, RIP) had a pano camera that I think he called ’My Obsession’ that either used a Mamiya back or maybe a 35mm 250 exposure back.

I’ve never played with the Mamiya Press back in real life but here is what I’m wondering. It you combined two 6x9 backs, could you reverse the feed side so both of the film containers are next to the lens making a bit smaller and tidy-er camera. I guess my next question would be about the advance, would a 6x9 back let you shoot 4 6x17 frames or is that extra mm on each advance going to cost a frame at the end of the roll…

Just thinking and wondering out-loud before bed!

ow hey Dirk,
thanks and yess, camerabuilding is so much fun!! I should have find this forum a longer time before, so much beautiful camera's (you and others) have been made.
I took a look at the back, but Mamiya made it quite complicated.. although the lever is on the right side, the up-spooling spool is on the other side, so... there is a connection from the lever all the way trough the back to the other side ... when you cut them... you'll have to connect that again..
in some way....the older ones are more simpel, but the upwind spool is connected on the side where the 'bulb' is heading to the back of the camera... and the camera will get 'bigger when you connect two of them.. back of the Marshall press is perhaps beter, although it is not removable... and the brooks....but they are....expensive.. It is nice to think things over and try to hack the usual..have a good night!

@dirkfletcher maybe I'm misunderstanding. You would like to make a Mamiya press back into a flat "U" shape from the "S"? I guess it could work if you spliced the same side from two backs, although the back would need to be perfectly symmetrical from top to bottom, which they appear to be. But you'd need to preserve the left sides with the take-up spool and the advance mechanism, and this section is behind the film gate. So you wouldn't save any space. Some backs have an advance lever on the right side (vs. the knob on the left), which is still the supply side: there is a linkage from the lever to the left side gears.

I'm pretty sure a 6x17 frame is twice a 6x9 frame. So a double advance should be just fine.

A while ago I made this 'redcam' a transparant red box with a lens to be used as a
'afgan-camera,' but with the capability to see the proces in real time happening IN the camera..
I like the idea to make the magic visible and if you like it more simple you can use harman direct positive paper.. but my cam is at the moment made of white transparant plexyglass and red foil taped in it... (it is not nice transparant, a little Matt... ) does any body know a place where I can buy nice transparant darkroom safe red plexiglas ? to build a camera that works, AND is PRETTY to look at?
