I've seen references to a 70mm back for the Rollei 6000 series cameras in an old catalogue and on the internet, but I've yet to see a picture of one, let alone one for sale. Do these actually exist? And if they do, do they use the standard 70mm cassettes? I have a bunch of 70mm film, and a 6008 seems like it would be an ideal way to run through it.

I have 70mm backs for Hasselblad. I love playing around with 70mm. I say find the elusive back!
Hasselblad ones seem pretty common, so I guess 70mm was at least somewhat popular with those cameras. I shoot 70mm with my Mamiya RB67, which is a lot of fun. What other cameras (besides Graflex) do 70mm?
Combat Graphic
Nice camera. Seems like it may be a while before I run into one I can afford though :-(
Mamiya RZ67.

I have a very long thread on the RFF re: 70mm Film Fun Here:
Check out the HP5+ Hasselblad Underwater 70mm stuff

Great thread! I'm only about 30% through so far.
Those rubber wheels for the Hasselblad A70 backs are no longer around, right?

Dan, it looks like Rangefinder forum changed it's address?
I had to go "manually" to find it (after so much time passed since my last visit there)
OrientPoint, Dan ( Nokton 48) was very generous to sell me his last set of rubber wheels for A70 magazine. Before that I was talking to machinist and those can be machined fairly easily, if you know right dimensions. Let me know if you need measurements?
The Bronica ETR series have an official 70mm back, so i'd guess the SQ series also had one.
Yes please on the dimensions. I'd love to have an A70 back working with non-perf film, as most of what I have is not perforated. It looks like it's easy enough to install the wheel once you have it.
That's the first photo I've ever seen of it. I would imagine it was expensive given the extra motor and suction. I'm guessing I'm not going to see one for sale any time soon.
Hi OrientPoint, sorry for "technical drawings", as you see it's not my strong point. All in mm. That 2.5mm central hole is threatened. Most likely metric? Your machinist will have to measure screw that holds gear wheel you are replacing with this one.
Please let us know how it goes? It's not big deal for machinist to make a few pieces at the same time.

Thanks! Now I need to find a machinist... maybe SK Grimes can do it?

Definitely check with SK Grimes, maybe they even have some alreaready in stock? Back in the day one portrait photographer from East Coast with Mexican last name (sorry??) was making those wheels and selling them. That was what I was able to find a few years ago when I was looking for them.
I'm sure any machinist can make it, it's not complicated part at all. Now, there is question of the price you are willing to pay for it?

I wrote to SK Grimes. If anyone can do it it would be them. Price-wise, we'll see. Thanks again for sharing the dimensions!
Anyone with a home-lathe can do it.
I don't have a home-lathe or know anyone with a home-lathe. Or even a lathe-lathe. I also don't have a 3d printer, although maybe the time for one in my home has arrived.
For me Grimes is actually the closest machine shop I know of that might do small parts. I'm not far from Pawtucket.

They do exist, in fact in 3 different versions. I got one for the 6006 (no film speed wheel) and there is one that does have the film speed wheel. The one pictured above does not have the data back nor the film speed wheel. So that makes at least 3 versions, maybe 4 if there is one with both film wheel and data back. Now I hope I can soon find one of these Watson/Alden spooling contraptions to run a roll through it.
Mine came without the vacuum pump but it happens that it is exactly the same as the Mamiya one (I tested) just like the data part as the same is that of the 220 film back and most probably comes from Nikon…
Well, that gives me hope that I'll find one one day.
I have an Alden 70mm bulk loader. It's nice to have, but it's really not difficult to load cassettes in a darkroom by hand. Given how rare/expensive the loaders are I don't know that I'd wait for one. I have several types of bulk 70mm and all but one I load by hand.

For me, nice point of using perforated 70mm stock is that perforations are great guide for cutting them off. Way easier to deal with 60mm wide negative than with 70mm in term of storage, scanner, negative holders etc. I'm using my unperforated 70mm stock for making 120, 127 and in near future 828 format rolls. Still waiting to use unperforated stock in A70 cassette.
