    Default Why a Copula?

    Sugar house.
    Why are they not just slanted up in one direction with input on the low side and output on the high side? You know 6' wall on one side and 8' wall on the other?

    Just curious.

    2012 4 taps and a bunch of propane
    2013 12 taps and a new home made 1x2 flat pan fit to an old wood stove, more propane
    2014 40 on tube flowing down hill to a 1x2 and 3 steam pans on emergency arch. (Drowning in sap)
    2015. New 2x5 flat pan and much better arch. 1x2 on new rocket stove ( this thing cranks, can't wait to use it) 60 on tubing into 250 gal tank. 6 on buckets just for comparison and a little extra!
    2016. Not a good year with the mild weather winter.

    That is a very good question, And a great idea to test out. The only thing I could think of would be wind ? My cupola is 8' long with two 20" doors on each side. Depending on how windy it is or the direction, I can adjust the doors differently to help counteract the strong winds. If the cupola was pitched higher in only one direction it may not work so well with strong winds. Just a thought.
