High Capacity Film Development.

I hear a lot of people say that and never understood why. I load all my reels by gently pushing the film onto the reel, I don't even have to twist the reel. I think the key is to cut the edges of the film and make sure that the reels are bone dry.

Excellent information!

Thanks I will try that

In a few weeks I can offer a new rotary processing system. It will work with Paterson, Kaiser, Jobo, AP drums in rotary and can control the temperature till 45C. Price: 1/3 of the Jobo CPP-3 processor with elevator. :) Partial made in France and Germany.

I am intrigued by this. Please post more info when it is available.

I batch process with jobo 1500 system tanks. I have two sets of a 1520 two reel tank with two 1530 extenders which holds 8 35mm films, or 10 120 rolls (double loaded reels). I can also do a mixed tank of 5 35mm, and 4 120s. This set up uses 1L of liquid when doing rotary processing. I find it the most efficient way to use a 1L tetenal c41 kit. As I have two matching sets, I do them one after another in one session.
 
The 15xx reels are designed for inverse development. The 25xx reels are especially made for rotary development. 15xx reels in rotary are critical in even development when using in rotary.
 
Here is my new JOBO equipment. Six 2501 reels (set to 35mm) and the JOBO 2505 Film Loader, for the 2501 reels. This has not been easy to find. All together you can run six 35mm reels in a Mutitank 5 (which I have), and two rolls of 35mm per 2501 reel. So that is twelve rolls at a time.

Very high capacity. Now I need to learn how to load it!

The key seems to be the anchoring of the film at the start and when you add the second one on the roll. You need to practice in daylight first, I'm afraid...
 
Thanks Marek!
This came "new old stock" in the original box and included a box of 35mm for practice loading. When I have time I will consult the instruction sheet
 
What Developer are you going to use? Often there's a minimum amount of developer you need to add per roll and the tank might not fit the quantity of liquid required.

I have been using straight replenished Legacy Microdol-X which requires a very long developing time. Twenty five minutes on a Unicolor Unidrum at 20C

Here's a typical result. Eastman 5222 XX is my preferred film.

I am not familiar with Microdol-X, there's no minimum quantity per roll suggested? I know for D76 and for Rodinal there's a minimum milliliter amount per roll. For example Rodinal 1:50 would not work as you need an amount of developer per roll (which I forgot) that wouldn't allow you the 1:50 dilution as the liquid would not physically fit into your tank.

Good luck and Eastman 5222 is also my film of choice (lately the only film I use!).

With a big tank last time I used 2000ml of developer (which is more than JOBO recommends for the Multitank 5 but more dosen't seem to hurt anything). I've replenished the same Microdol-X gallon for over three years. It seems to me to get better with age as it "seasons".

I don't use dilute one-shot developers. Here's the Mutlitank 5 on the Uniroller

At least with the Jobo reels, being completely dry is absolutely essential.

I just processed a batch of four 35mm films in a Jobo 1540 (1510 + extension tank), loading in a dark bag. The first film was a nightmare - bizarrely, the start of the film wanted to curl in the opposite sense to the rest of the film. After much pain trying and failing to load it, I had to cut off the first 6 frames to get it to load.

Unfortunately, after doing this there was enough humidity from my hands that loading the remaining films was also difficult as the film binds to the spool rather than sliding. In the end I had to put what I had in the tank and open the bag to dry it before finishing the loading.

One thing that I find helps with loading the reels is always to round off the corners on the leading edge of the film (when cutting off the leader).
 
Inverse processing: Jobo 1510-1520 or 1540.

I need to buy some old old rolls long expired so I can practice loading 35mm 2501 reels. This thing dosen't operate like anything I have ever encountered in all my years. Today I may have time to stop by CCG, can't think of anyplace better to buy cheaply some old nasty film for practice loading purposes. Maybe at least a dozen rolls..... I've figured out how it works. Ingenious, but tricky to load. No wonder peole get frustrated and sell these off. I'm sure practice in the light is the key. Yes it won't work without trimming the corners of the leader.

As you can see below, I had it put together backwards earlier. Hee Hee. Here is a roll of old color film almost completely spooled onto the 2501 JOBO reel. When you get the first roll loaded, you push in the red stops, and load the second roll onto the outer part of the reel. If the roll is kinked or bent at all, it will NOT go on smoothly.


Time to practice. The clips to grab and hold the second roll are on the inside of the red push-in stops. All built with typical JOBO precision. Did you know they used to be distributed by Leica?

For every new thing sometimes it is the first time ...... :)

BTW the TAS can also handle the Jobo 2521 tank with the 2509N sheet film reels.
 
Still had it backwards, Hee Hee Hee. NOW I have figured out how this thing really works! And I have loaded twelve rolls into six reels and MAN am I glad I bought thirteen old 36 exp rolls from CCG to practice with. :bang:

Yes this is touchy to load, but I have it down now. In the top photo, you thread the inner roll in and HOLDING DOWN TIGHTLY, wind it onto the reel. You really have to be careful doing this, it can mis-thread. In the second photo, you push the red clips in, wind backwards to lock it, and push the second (outer) roll on, winding slowly and carefully, while holding the plastic loading piece tightly. So it works reliably. I think I will practice some more before loading real rolls. But I am confident now that I can do it.


Here are twelve (scrap) rolls, loaded onto six of the #2501 JOBO reels :)

Fotohuis, I came upon this post when I looked for references in these fora to the Heiland TAS. How long have you been using this, and can you tell us about your experiences regarding user-friendliness, stability etc.?

I hope you can help. Thank you in advance.

It's an old thread, but I hope you read this anyway, Nokton48:
Where can I get an instruction sheet for the 2505 film loader?
Could you post a scan or simply a photo of yours?
