They should make a version that does the 4x5 Expert drums. That would be a great device.
Ring was just in the packet..anyway the cog in tightly and quite difficult to remove so I suspect the ring was for a different tank (maybe the Chinese knock off Jobo...?)
You can do 4 x 5 in the appropriate JOBO drum for 4x5
Yes but I mean the Expert drum specifically (not the regular Jobo tanks using the 4x5 Jobo reel)
Anyone bought this machine.. It comes with a cog and a rubber 'O' ring
I have a Jobo tank and am wondering just where this ring is fitted as fitting it on the thread side of the cog stops the proper seating of the cog...Just wondering if its foru use with a different make tank??

I ordered one as well.
Are you referring to a cog like the JOBO #1505 COG?

Got this answer from Reflex overnight ..
The o ring is a spare part for replacement in future. You only need to put the cog to the Jobo tank. And it will work fine. It does. with a very hard push
I didnt ask spare part for what![]()

When I received mine, the rubber o ring was already installed on the cog they provided. I was able to pop their cog onto my 2520 Jobo tank without any problems. There is an extra o ring included if needed.
Let us know how the unit goes.
I'm pretty tempted because my C41 processing system is rather agricultural to say the least.
I'm sorry, but I'm obviously a bit slow and reflxlab site is unfortunatelly of no help...
I have Jobo 1520 and 2521 tanks (with magnets and silicone lids) that I use with my CPE 2 without lift. Can I use those tanks with the Ice Cream Evo? Would I have to remove the magnets from my tanks? With the cog installed on the tank that would mean that tank inversion development is no longer possible.
It would be then better to buy a dedicated 2521 tank for this machine, since taking the magnet on/off will definitely break the pins on the magnet and putting the con on/off is obviously no fun either...?
I've done 3 developments so far and all have turned out well.

I am curious about the results! I wonder how evenly a clear, vast, cloudless sky will be developed as well.![]()
but one never knowsThe "thing" arrived yesterday.... First impression is ok, my old and broken Jobo CPE2 is not much better than this. I need some extra stuff to use it for developing (C41), I wold probanly use it in a couple of weekend with a test roll.

'The packaging was surprisingly good for a budget minded product.
They didn't skimp on it that's for sure...Good luck, as that won’t likely come from me. I prefer to mainly shoot when there’s cloudsbut one never knows



It rotates forward 30 times, stops for less than a second, and then repeats with 30 rotations in the reverse direction.
I’m wondering if yours does the same thing.
