My thanks to all who replied to this thread. Well I've gone over to
the "dark side" & built my inclined offset head still. I've posted
some pics to the pictures area under the folder "Inclined Head"
Did my first run - re-distilled some 60% tails & other junk. Output
was 95% at 350-400mm/hour.
Question: If I now build a short column (about 12") and put the
inclined head on with no packing, will it double as a pot
still/stripping still. I think it should, but I haven't tried it.
