The end fitting connects so the line circles the tree, then run the 5/16 from tree to tree, zig zaging so each tree helps hold the elevation, also go past non maples the same way. At the bottom I sugest you also have an end tree connection to hold tension. When connecting have the top end tree "drop" face up to tap and at the bottom have the "drop face down to drain into your collection barrel. Tap the trees and start having fun.
Dave Klish, I recently bought a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
