Indeed Hewes reel do not permit rolling in both directions or the film will slide out, so I switched to the jobo plastic reel and it's much better except for some streaking (maybe bromide drags) in the 2 first frames toward the center and still a slight denser streak in the middle of every frame...

My mistake was that I was rotating both ways. I tried again rotating only in one direction, so that the film would be push toward the center and it stayed in place. But as a consequence there was not enough chemistry in the tank to reach all the film surface which turned out to be partly...

Ah thanks ! Off course this extra clip makes perfect sense now ! So if they are not made for the 2500 system do you have experience of them working fine with this system ? I am also wondering if rotating the tank in one direction only, the one that would "push" the film toward the center, I...

Humm there is this extra clip, maybe it serves a purpose ?

I'm used to the hewes reels in inversion tank and I do use the clip when inserting the film although I don't understand what you mean by crimp the end. When I realised that the film was out of the reel after development I did some simulation with water and what is going on is that at first the...

Thanks! Did you use them in rotary process or inversion ?

Oh well the film does not stay into the reel anyway the rotation makes it slowly slip of... I don't know why hewes made reels for the jobo system if it does not work... So I have to buy more reels now and I'm not even sure this will solve my streaking issues...

No not at all. Quite the opposite I just don't want to put too little chemistry by following recommendations. Unfortunately I only have the hewes reels for roll film.

Interesting, Since the inner diameter of the reel is the same in both to accommodate the center column the inner most layer of film should be the same. I'll try with just a tad more then. Thanks Matt for putting light into my brain!

Thanks but the meaning of my post was that since the diameter of the Hewes reels is smaller that the Jobo's one I could off course waste film testing but maybe someone has this equipment and can spare me the waste...

Hi everyone, While I am stuck in an endless quest to solve some impossible development issues, I decided to try constant agitation and invested in some Jobo 2500 series tanks and roller base which I would like to use with my Hewes reels. The ones made for Jobo/Perterson tanks. The problem is I...

sorry

Hi, Sorry this is out of topic but I cannot find out the amount of chemistry one should use for each 120 film with these reels in 2500 tanks for rotary process. Thanks in advance. Vania

Good news for you ! I am surprised though as I have been down that road many times (1 minute initial agitation and developing times over 10 minutes) and it did not solve anything in my case... It just makes the streaks less noticeable. What do you shoot for your test ? I fill the frame with a...

Thanks I'll look into it. Ironic as I've always considered semi-stand as a call for trouble but it gives very interesting results when it works!
