Thanks Julian

Good plan with the heaters, I'll measure that, particularly the cone mounted one as you can't tell where is sits now, let alone with insulation.
Hmmm, Dick might read this and shake his head, I'm sure he's probably already told me about the de-mething options.

I've head or read so many different ways of doing it, its hard to figure out whats what.
Do you all "bubble" or is the "inverted spoon while boiling it out" a sufficient alternative?
What about the pressure drop evaporator, is that instead of bubbling?
Or letting air into the venturi during the de-meth stage, is that an alternative to bubbling?
I like the idea of trying to combine the "air in through venturi "and "spoon fountain" do help with the distillation. Would I still need to bubble after this??
Sorry for all the questions. Perhaps I should go over the wiki again.
