After not using the tank for a while, I've got my Jobo in action again (I've been away from it trying to use up my stash of color quickloads). Never liked rotating the thing by hand, so I bought a Uniroller, only discovering after the fact that the tank I have is too short to be used on the Uniroller. It's the one-reel 2521 tank. It doesn't reach across both rollers. So they said it couldn't be done.
At first I tried to make a sleeve for the tank out of a cardboard oatmeal box, but it did not roll reliably. But I realized all I needed was something to hold it level and something to keep it from falling off. And then I discovered rather by accident (rooting about in the kitchen drawers) that a steel cannoli form fits precisely in the hole in the magnet base. Then plug it into the Gralab and use the Gralab to keep it from walking off the edge.
I just wanted to show this off.
