But I digress. Point is, before I start scurrying around town picking up all these not-so-cheap parts, I'd like to run my plan past the experts.
My plan (not drawn to scale):
I saw someone's diagram which showed a support towards the bottom of the Liebig - how necessary do y'all think that'd be for mine? I only plan for the horizontal arm to run far enough for me to comfortably solder in that gate valve - no more than a few inches - so my instinct would tell me that weight of the arm wouldn't strain the joints TOO much ...
OH - also - I'm sure I've just overlooked this in my reading, but what if I put a reducer on the bottom of the column to take it down to, say, one inch for the screwing-in bit? The matching fittings for my boiler(s) would be cheaper that way ... and the vapor velocity from that bottleneck would come back down as soon as it hit the wider section of pipe in the column, wouldn't it?
Sorry for rambling on ... I think it's probably a sign of my excitement at the prospect of building a real reflux head after all this pot stillin' ... thanks for any and all input.
