      That's really interesting, a 12" column that delivers as good as 1 meter column with scrubbers? I'll make an educated guess after
      peeking at the theory section of compleat distiller. The packing gives less resistance to the vapor and liquid flow thus having less
      pressure than a column filled with scrubbers. You have found a way to efficiently distribute the refluxed liquid over the whole packing volume in order to make it more efficient?
      Nice try Riku!  Sorry, but that is not the whole answer.  It's not just the packing . Good packing helps, but my first experiments were carried out using good old scrubbers, and a 4"  so-called 'column' gave me 91%.  Pic attached:

      Would a taller and wider column with more power provide additional benefits in separation via increased reflux and packing volume? It would be very nice to have really precise cuts for all the components while maintaining (or increasing) the output.
      It might.  Haven't tried that, so unable to comment.

      Shame I allready built my system, otherwise you'd have one more customer calling. Allthough I might consider that copper mesh packing in future.
      Let me make one thing clear.  This is not a blatant attempt to advertise to the distillers groups to rush out NOW and buy our equipment.  Of course, if you want to do that, then we will probably give you a glass of wine to enjoy as you wander around the store :-)  The majority of customers will be those who are not on the distillers lists at all, and have no interest in messing around with soldering irons etc and annoying our families with our smelly experiments.  When I posted to the lists about our new website, the main motive behind it was simply to inform.  Of course, being absolutely honest (which I always am) there was the ulterior motive of gleefully sticking a pin in yet another Old Wives' Tale about whether size matters.  Bottom line:  if you already have a system that delivers all you wish, then stick to it.  The fun is in the building and proudly saying "I made that!".

      i posted below about the pipe in pipes not working. this was when setup for a thumper though rather than a packed column. maybe they are onto something. what

        i posted below about the pipe in pipes not working. this was when
        setup for a thumper though rather than a packed column. maybe they
        are onto something. what if you have a packed narrow pipe with a
        closed pipe sitting on top of it (like a upside down glass). this
        pipe is packed to and has room at the top. then this pipe is inside
        another packed pipe. so vapour goes up then down and then up again. i
        will sketch it if you cant understand what i mean. if you have a
        condenser on top you will have a temp variation in the initial thin
        pipe. say 90 at the bottom and 85 at the top. now what will happen
        when the vapour at 85 goes back down the outer pipe and is heated by
        the lower part of the narrow pipe still at 90C? i remember asking
        what happens when vapour goes DOWN a packed column, but cant remember
        the answer
