70mm Film FUN up ahead

Hey Rob-F,

Basically you have three choices for developing tanks for 70mm (that I am aware of).

1) Kindermann 70mm Daylight Tank and 70mm stainless steel reel. This is what I was able to find after looking hard for a couple of years, I think I bought this one on German Ebay. B&H used to sell these new for $299 back in the seventies. They are around but don't come up all the time.

2) JOBO makes a 70mm reel that fits their tanks. I'm not that familar with it. But they are around.

3) Honeywell Nikor made a stainless steel tank and reel for 15' of film. Looks like a giant 35mm Nikor daylight tank. They are around.

My Kindermann 70mm Daylight tank & SS 70mm Kindermann Reel. To the left of it, is a X-Ray 70mm Plastic Reel for processing dental x-ray film. I found it on the internet, it was only like ten bucks new! Will not hold 15 feet, but will hold thirteen feet. TEN BUCKS!

Regarding loading, in the dark I load the spool was full as I can, without scratching the outside edges of the film, when I assemble everything. It's all done by touch. Scissors I keep in my back pocket, so I can find them! ;)

Jobo 2517
Can also be mounted in Testdrum 2820(made for 10x20cm prints)-400ml
Also the 2500-reel-trick(3 parts)-combo can be mounted in Testdrum. only did not use but its lighttight.
And the trick with the adapter-only one 2500-reel needed. Nokton24 has a drawing for 3D-printing. Is it the same one could find as file? the latter not allowed for commercial use? Holgamods should offer yours Nokton24. but he needs a 2500 reel then. maybe Catlabs could send him one for free.

I really don't have a good "read" on how many feet of film will go into your Baby Backs. Too many variables. How much space is between each frame, how much leader is required, etc.

Get ahold of an English instruction sheet. It's prolly all in there. Sometimes you need to consult the destructions. LOL

The good thing about WL Surveillance, is that it is 150 feet, not 100 feet, like some of the thicker base films. So you get 50% more film per can. That is a good thing.

Don't waste money on fancy Linhof film cassettes, they just slapped their label on it. The regular Kodak ones are fine. In fact, actually they are ALL Kodak 70mm film cassettes.

Good luck with it. I like beefy negs too, and I'm getting good n beefy with the WL and D76. Shadow detail is copious, so this is a true ISO 400 film stock.

Linhof thought foreward making a thicker core and using a slit to hold 70mm film. no need for a clamp.
regarding Hasselblad A70:
There is a workaround for Unperforated film-use.
Would it also work with 120-longroll? or must the wheel work, the wheel which is no transportation wheel but tied to the spacing-mechanisme?

I mean how many shots can you get out of say 100 or 150 ft? Would really appreciate not having to change film when im shooting london fashion week as carrying a RB67 is bad enough but changing film every 10 frames killed me.

5m normal thickness 55 images. counter goes to 65.
since i loaded 0.1mm (4mil)Vericolor HC 6.5m for roundshot 360 that means-if you dont want over 65. load approx. 6m to get 65 shots. there is very thin PEO 0.06mm 2.5mils which i have avipan 200. but didnt check lenght. mamiya RB67/70 vaccum-back advised. Suction Bulb needed.
That means Technical Pan 6.1m would easily match RB 67/70m-65 images-see above. there are 6,1m rolls or were.

BULK LOADING 120 FILM

From the internet, here is a home made 70mm to 120 size film slitter.
This is for slitting 70mm film, then re-using the 120 backing paper and respooling it all together.
I have never done this myself, but I certainly have enough 70mm film to try it! :)

Xkaes at aol dot com Fred can offer all variations of slitters. Its made in China. and very reliable, had contact with the producer and he explained how its working. No it will no be available from there. Its very affordable. i have a version with one blade to cut down complete perforation on one side, leaving alone the other side. if two blades are used not perforation are cut which could be a danger in machines. anyone has experience?
I have also 70-35mm cutter. a film-spolling-holder would be nice.
Holgamods was thinking about a 61.5mm downwards system. if then he should think 70mm downwards....

And here is the 3D model of the Jobo 120/220 reel adapter, to accommodate 70mm film. This will take a short piece of 70mm
But it will fit in a Jobo multi tank 2500 series. Useful! This would be fantastic for test-developing a couple of feet of 70mm film.
I could see using this quite a bit.

Someone here should make these adapters. I would buy one!

send the drawing to Holgamods Randy Smith. He can print and offer it affordable.
 
Michael,

I'm Nokton48, not Nokton24. And I am NOT Trevor Allin, he is over at the Kiev forum. Over on the Kiev forum I am HASSYDAN.

That 3D design is not mine. As mentioned above ^^, you can use an old Efke 25 35mm film can bottom, and cut the bottom part off of it. It will tightly hold the JOBO 2502 reel column together. Them simply carefully glue it together. I have no need for anything from Holgamod.

SEE the Efke 25 film can holding the reel together? No cost at all!

I was initally unhappy that my new Graflex RH50 was NOT pulling film through the back. Finally, I twisted the black knob (upper right) to and fro, and after a bit finally freed up the mechanism. No doubt sticky from disuse, but now, it's pulling the unperfed or perfed 70mm through like a champ. Notice the new foam rubber strip I have installed. The original crumbled to powder when I touched it.

Notice the soft rubber rollers; that is what will pull unperfed film through this back. No need for sprockets and perfed film.

Cal,

Is this the one you bought? I was going to suggest you pick it up: Looks like mine, except mine is Grafloc 4x5.

You should get a 180mm Schneider Tele-Xenar to complete your Baby outfit.

Dan,

That it is. Should be delivered this Wednesday. Always best to change loaded magazines to avoid fogging film or light piping.

At B&H I bought 1000 feet of 3 mil 70 mm sleeving. I bought the 3 mill over the 2 mil. Cost was $78.00, shipping is free, and it was special order. 1000 feet is enough for 369 rolls of 120 equiv. Remember a roll of 120 is only 32.5 inches of film.

I shot a roll of Tri-X and three rolls of FP4 Saturday to test my Linhof Tech IV with the repaired 100/2.8 Planar (lens separation). The camera is amazing. The negatives mucho sharp, retro bokeh, and kinda low contrast. Mucho mids. Walked from East Harlem to the South Bronx via Randell's Island. Kinda like carrying a 7 pound baby, so it was a slow walk.

This was a successful field test.

70mm tri-x unperfed by Nokton48, on Flickr

Unperfed Tri-x 70mm, this was in date when I put it in the freezer. This will go in my Graflex RH50, or my Beatty Coleman 70mm Transet back.
Or when modified with the "rubber wheel" it will go in my Hasselblad A70s.

I'm going to load 20 6x7cm exposures in my Graflex RH50 to get started. This way I can process that roll on a JOBO reel, along with a load of 35mm Eastman XX 5222.
 
The Cyberdoorman failed to text me yesterday. Evidently my new CINE was delivered yesterday.

Having three CINE's is practical because loading in the street is to be avoided. Also because two are 6x7 and one a rare 645, I can effectively change the FOV on my 53/4.5 Zeiss Biogon by changing formats: I get a 35mm FOV in 645; and a 28mm FOV in 6x7.

So my question for Dan is buying a large JOBO Expert tank and cutting it down to hold two 15 foot Nikor reels too big and heavy to manage? I know it takes 2 liters to cover just one reel, so I'm talking about using a bit more than a gallon with two reels.

I'm debating to make or find a daylight tank for one reel. Since I already have a Nikor dip and dunk rack that can handle 18 120/220 reels that it might be more practical to build a light safe for three 15 footers and utilize a dip and dunk system that I recycle from my 120 use.

Cal,

It will take at least several minutes to fill -or-drain a gallon of chemistry. With three or four minute souping times in Diafine, I wouldn't think that would be practical. Much better to use a rod to lower it into the soup. Also then you could put on the light tight cover, maybe? I find it very aggravating how long it takes to fill the Kindermann, and soup goes everywhere. I certainly wouldn't use this with short developing times. Also a gallon of chemistry is going to be tough to agitate by inversion. Not sure I would want to do that.

Dan,

Thanks for the response. I already have a Nikor non-daylight tank that resembles a stainless steel hat box. I could use that as a film safe.

It makes sense what you say. Pretty much is easier to dip and dunk by going dark. Also it fits in with my 120 ambitions. "Crazy is good," I say. Kinda lucky to have three 15 foot reels.

My experience in doing 2 liter tanks does not really scale up.

Cal
 
UPDATE: The tan CINE arrived. The two cassettes are Kodak versions, and they have the clips.

These particular cassettes were difficult to open. Very-very tight. Kind messed up my thumb nail trying to open them. Any trick to make them easier?

Gorbas,

Thanks for your response. I found a stainless steel vase that is shaped like an oversized shot glass. I'll check tonight if the bottom base diameter has enough girth to accomodate my reels.

Yesterday I got a 1000 foot of 70mm sleeving delivered.

I'm also thinking I might be able to buy stainless steel cooking pots.

Pouring two liters is already kinda crazy.
