Great to hear from you, literally only yesterday was I wondering how you were doing!

As far as home distillation goes, there's also the option of building (much of) the apparatus out of copper pipe, joints and fittings. I've done so myself and it wasn't so difficult. I may have a few practical skills but I'm far from being an expert. Building a Liebig condenser this way is barely intermediate level, the main trick being that you should be able to reliably make watertight solder joints.

If you can't be bothered with this, the silicone tubing will make a functional alternative, but again, you have to be sure that the seal around the exit pipe is firm, otherwise you'll get coolant in your distillate.

NMT freebase will certainly dissolve in ethanol. I'm guessing you're going for a dried lime paste before making the alcohol pulls, after the disappointment and frustration of the vodka/lime precipitation experiment - something which, incidentally, I'm still rather sorry you had to go through.
