@ 6:33 @ Nico! heard of the chap. he's awesome (: As for the 2509N, can it fit 2x3 sheet in 6x9 mode? Or what's my options for 2x sheets n a 1520 tank in rotation using less olution? Is it compatible on my existing 1500 motorized system?
Another great video :) A Patterson reel can take two rolls of 120. Feed the first roll in using the ratchet bearings. once it's all in, continue to push the film around the spirals with your finger until it hits the centre. Then load the second roll as usual using the ratchet bearings. Two 120 films in one reel.
As mentioned, Paterson (or, I suppose, any other reel taking a full length 135 film, and which is also adjustable to 120 width) can also do two 120 rolls. The ease with which that can be done varies. I have only tried Paterson and Jobo, and actually found it easier to do on the Paterson as I didn't practice enough with the little Jobo red clip! My own fault in other words. With Paterson, a useful tip from a colleague was to keep the tape (which fastens the film to the backing-paper) on the end of the first film and used that to stick the second roll to the end of the first one loaded, in order to prevent any overlapping area.
great video , but one thing ,you don't need a special cap on your jobo tank if you want to use it on a rotation processor , you can buy a magnet to fit on the back of your tank. The special cap is only needed when using the lifting operation system.
Does Jobo 2400 daylight tank use a special size reel or are the reels compatible with all the Jobo tanks? I want to develop 110/16mm film. Why was the 2400 discontinued?
Hi Nico. How to develop BW in Jobo MultiTank 2? Fill it up completely with 1250ml of chemistry and use the tank as an inversion tank or fill it with 550ml of chemistry and use it as a rotational tank? How do we compensate for the constant agitation using the rotational method? Do we use 18* C and keep the same times as inversion method, or we use 20* and we subtract 10% time from the inversion method? Edit: As I understand, there has to be a certain minimum developer solution for every cm² the film occupies, so if we use Rodinal and 6 sheets of 4x5, a 1 : 50 dilution will not work very uniformly because there isn't enough active developer for every cm² of film in the tank... ugh... seems pretty complicated to take all these facts into account.
Nico be carefull, as at 3:50 if you push your fingers in too hard, you will definitely get a "paper cut", slicing your fingers, and possibly getting blood onto the film :-( a bad day at the office for sure. (as its not just paper, but plastic {acetate}) so has a greater tendency to cut you, as the material doesn't bend as easily, it stays stiff, so acts virtually like a straight razor, or a chisel blade, if you stroke it wrong.
I wish i would have known this when i got started. I just ordered the Fotoimpex Starter Kit which tied me down to Patterson. I've though about selling my tanks and switching to JOBO but i'm not sure if it is worth it at this point.
The automatic agitation and temperature control isn't really needed for black-and-white processing, so you can start with the very adaptable tanks and expand as needed by lengthening the tank (which is reversable btw), swapping the tank-lid and adding a magnetic drive attachment to the tank underside etc. The Jobo tanks for rollfilm and 135 use a little less chemistry than the Paterson design which can potentially save a little money, providing that one can get the right amount of developer-concentrate in to the tank at the dilution you want, bearing in mind the minimum required specified per roll. It is also perfectly possible to develop slides or C41 using a simple washing-bowl containing tempered water and hand inversion of the Jobo, Paterson or generic tank -- my first roll ever was Agfachrome in a Paterson tank, way back in the seventies, and the process worked fine.
Well, I have had exactly the opposing experience. My Jobo reels feed the film without any issues. But the Paterson reels always start to crease or scratch the film because it gets stuck half way through.

Two 120 films in one reel.
Thanks. Good to know. I was pretty sure one couldnt. Always make mistakes ;)
Hey, now thanks to your video I know all about Jobo's.
Its all about knowledge. ;)
We got to keep the knowledge alive.

Very true, I totally forgot as I have never used the magnetic connection, but will correct it when I show the different stages.
I'm still looking for a 116 / 616 reel same as 65 / 70mm? Anything or from 3rd party?
Hi Nico, aside from the humongous price difference; how do the 2501 and 2502 reels differ, please? I have a 2520 tank. Thank you.
Gracias Nico!
De nada!
Thank you another helpful video! )))
Thank you Gary!
Was there any information on the 2501 reels? Are they possible to load by hand or do you need the special loader?
Seems you do need a loader for it. Also I don't own it so can't help you with it yet. But will try to get my hands on one.

It does use a special reel. No clue why it was discontinued.

good info! I've never seen jobo stuff in the flesh so a run through like this is great to get an idea :)
Its a great system but alas not inexpensive at first.
Can you link to the video where you explain how/why you change the top of your Jobo tank to do C-41 / E-6 film?

Paterson tanks wont link together but the reels will work in all tank paterson. It might be worth it if you are planning on expanding.
You should do a video of how much is to get a simple set up of jobo. I saw the main machine at 1300 usd. But i bet there is a ton more to add

I will work on different setups for different uses and prices for it all. Good tip.
Now if they only could make their tanks liquid tight.
I havent found many issues with their tanks, but its true they have been around for a century so maybe the quality is a problem depending on batches.
those jobo spools are shit. I have one and the Paterson ones are so much better.
Glad you enjoy yourtr Patterson reels, Im happy with my Jobo ones. Guess we are lucky yo be able to pick in 2019.

Thanks for that Nicos. I've learned more here 🤗
Thanks! Hope to keep with this and show as much as I can.
