Here she is in potstill mode with a little over one third of her column attached and one roll of mesh inside. There was a dripetidrop inside that bugged me. But I can't taste the difference with or without.

Here's the crimped mini leibig. Who invented this again? Who ever it was, has a wonderful sence of simplicity. It does the job just fine :) Modular, kept together with a copper chain, but not sealed, to avoid siphoning.

And here is what she looks like from where I'm sitting now :-)

It's not "run" by the computer :) But I do have a cheapy USB thermometer, since I'm in front of the screen most of the time anyway. I see the temp all the time, while doing other stuff online. And the software makes it easy to take and save notes.

Only got 93% in reflux mode befor. Added a centerring and now I'm getting 95%.

Tell me more. How'd you make the ring and where'd you put it?

Sorry Braz :-) Well, I cut out a 2" circle of the 0,7mm leftover copper sheet from the slanted plates and drilled a 1" hole in it. Then I cut off maybe 8mm from a 1" tune and soldered it on to the round washer like disc. My column is 110cm and I just plonk it in the join, 60 cm's up from the boiler. I would have taken a picture of it, if it wasn't so stuck in there already :oops:

Edit: And oh.....yes, the 8mm tube bit is faceing downwards.

OK, got it. That certainly sounds easy enough.

I wonder if it would make any sense to add a second centering ring maybe halfway up the column to re-direct whatever liquid might have migrated to the tube wall on its way down.
