Part three, as amazing as things went, there are a few things to work on.
I have to move the pan a 1/4” to the right, I discovered after I started boiling it was barely hanging onto the right edge. That is an easy fix.
My stack last year never remotely got that hot, not even close. When my pan and base stack maker made the base for the base stack he made it different than i expected and the base stack is too close to the pan. I will try and move it a 1/4” more away from the stack, but I am not sure if that will be enough. The pan actually got a little discolored and it burnt some of the sap. I may see if I can weld a small extension piece to the base stack to try and move the pan a little further away from the stack, maybe a half inch more away from it.
I put to boil 110 gallons of sap and you could obviously see the gradient and I thought for sure I would have a draw off, but the thermometer never moved from the water boiling temperature. The weather is turning cold and I will not have another boil for awhile. I had my wife watch the evaporator while I collected today’s sap, so there will be not much sap to start a boil tomorrow, so I will not have a second boil.
I drew off two large potfuls of the densest sap. I may try finishing them. The rest I am draining of into pails, keeping their order and I will let them freeze and will use them to start the next boil, whenever that may be.
The stack was so hot it melted the tarp behind it, which I never expected.
