70mm Film

[aoresteen]

Way way overpriced. Jobo didn't sell many of them as they have always been high. But it will process 70mm film.

Kinderman had a nice tank/reel for 70mm; it sold new for around $200. Also Honeywell/Nikor had a 70mm SS tank/reel that can be had for around $200 or less when they pop up on eBay.

Yes this is way overpriced, though like you said not a whole lot of those out there. We have a bunch of the tanks, but never seen the reels or loader for 70mm. It does have the advantage of being able to load an 8m length of film which none of the others do, but that might not mean much at this point in time.

 

[polyglot]

Wow, they do not come up very often! Actually I think the (starting) price is vaguely reasonable as it includes a loader that itself is likely worth $200.

 

[CatLABS]

I think its worth any amount of money as these loaders are so rare....
I wonder - is there any reel out there that can hold a long roll of 70mm other then the elusive Jobo reels which require a loader..??

 

[Newt_on_Swings]

Its things like this that need to be 3d printed!!

 

[polyglot]

absolutely! you'll struggle to get good enough resolution for the spiral though.

I'm working on a prototype core extender to allow you to put 70mm on normal Jobo reels but of course only short lengths.

I had 2 Watson's (35mm) in my hands the other night talking to myself about splitting them in half lengthwise and plastic welding them back together with a spacer in the middle. My wife of course thinks I am crazy, but showed no inclination to either load the film or develop it.

(fair disclosure - i have nothing to do with this listing)

Well that leaves my cpe-2 out since I understand it won't handle the #3000 series.

It might leave your CPE2 out, but you shoudent rule out your future CPA2/CPP2....

Yes, have been to the page many times.

If you have access to a band saw it's very doable. The hardest part would be to cut the bottom off one of them and leaving enough material to get 70mm of height. You will need an empty 70mm spool to fit things up.

Last month I was totally going to give up on 70mm. Then I was cruising ebay and won a dedicated Mamiya RB Pro S with 70mm long roll back, no lens. The guy had been in business doing bank portraits for 20 years and contacted me. One thing led to another and after a fortune spent in shipping, I now have more 70mm than I know what to do with and need to get creative on using it. A lot of the long roll backs still have film, although probably no good. It does give me maybe 50-100' to experiment with ways to roll it, load developer tanks and such.
I have plenty of Hasselblad 70mm, Singer RH 50, Transet, Honeywell/ Nikkor, Camerz, Beattie and such.

I raise the point because I either have to find a reliable and consistent way to use about a 1000' feet of 70mm or spend way too much time getting it sold, traded or some such.

My current thinking is Chicago style processing I call it stuffing the ballot box. Based on exposed roll going straight into developer in darkroom, then to fixer. $89 x2 and done!

Nikor used to make stainless long reels in a few lengths up to 100 feet, and all the normal movie film widths, including 70mm. I even have one that's for 46mm (though I think maybe that was a custom job cut down from a Nikor 70mm reel by some end user.) They made a loader for all those too, just swap out a couple of rollers and guides on it for handling different film widths. The tank setup had a lid with a rotation/agitation knob that screwed into the reel, and then 3 nesting tanks for chems; you'd move the reel from one tank to the next (in the dark!) but then agitate in the light if you wanted to.

Did Wing Lynch ever offer a 70mm insert On their model 4? I field stripped one I got here and have it in an out door shed. They had plexi canisters with holes for chemicals to pass through.

Specifications say: 5m. you are confusing with other tanks holding 8m but other filmsizes. 16,35, 46, 60, 2x 35 can load 8m, 70, 126 and 127mm reels take 5m. independent of thickness..... I have datasheet and universal instructions.

I was given an almost new Kindermann 70mm tank and reel recently. Being a Hasselblad owner I've been contemplating acquiring a 70mm back and some film. There are some affordable and viable options permitting the use of 70mm for cents a shot in the link.

That's my thread Please everybody go over and contribute! We are trying to build up a bank of info on 70mm.

I cut the bottom off an old 35mm Efke 25 film can, and it tightly fits the JOBO 120/220 reel. Converts it to the wider 70mm. I've used it and it works great. Glue it all together.

I understand now the 70m-film in the reel......
Can you explain what you did to center the film? It seems you added 35mm-reel. Simply pushed in? Never used 2500-tank. only have 2800. and testtank 2820 to take up 2517-reel(= official 70mm reel, 178cm, i could load 172cm only maybe the 6cm are the ones Nokton48 is showing above.

 

[Nokton48]

The reels simply push on the center column. You can use any combo to fill the tank.

Do you have a pic or link to that Alden? All my searches turn up the 35mm version. It would be fantastic to see your home made developing tank too.

Sure! Here ya go:

The Alden 70mm bulk loader:

My home made 70mm tank. I bought the 70mm 15' reel first and then went looking for something to put it in. It fit in an old Omega Chromega processing tube/tanks for prints. It's about 6 7/8" inside diameter. Takes 96oz of developer

View attachment 59556

The problem with the tanks was I could not invert it for agitation or all of the developer would spill out. I had cut down a 120 16oz SS tank to fit a 127 (46mm) reel and I had saved the cut off SS ring. I simply epoxied it to the top of the Chromega tanks and a standard Kinderman tank top will keep the liquid in.

I had to cut down the tank as it was quite tall. More epoxy and silicone sealer. I made this tank around 1988 and it's still going strong.

I also mad a 70mm reel that will fit in a standard 16ox SS tank. I took a 35mm 36exp reel and cut it in half. Using a dowel, I spaced the reel ends 70mm apart and epoxied the whole thing. Did this in 1978 to process 26 exp 6x6 frames in 16oz of developer. Works well

Alden 70mm Bulkfilm Loader
Right from the beginning i removed the counter/sensor(taped the hole) in fear of it could scratch the films.
No need to be fearful? Can i reattach?
NB: I was unlucky and crashed one part of the loader. Queens City Plastics replaced it with no costs for over the ocean-shipping. Was very surprised since they didnt allow to purchase directly. Now i am treating it like raw egg.

 

[darkroommike]

At the risk of being a party pooper, what exactly is the point? I get that it's wider than 120 so provides for a slightly larger negative but it doesn't seem enough larger to offset the trouble and expense to me.

I think the 70mm image area is exactly the same size as 6x6/ Of course you won't have any backing paper print through issues and many more shots before you need to reload.

Here is another view of the Hasselblad motorized 500 exposure 70mm film back. Mine is said to be in mint condition, and has the original travel case included.

This is on it's way to me. Like a dream come true.................
I know back in the day this item was as expensive as a car!
