I took sessions 1-2 about 15 years ago. Great training.
I had been cutting trees for over 30 years at that time and "thought I knew all about it" Boy, was I wrong. I learned far safer methods to address all situations you might encounter in falling a tree, and the safe way to handle problems (like spring poles).
I highly recommend every one who is going to cut any tree heavier than you can control the fall by hand to take the course. By the way, if you have workers you hire in maple work also cut any trees, most worker's comp insurance carriers require the workers to take the course too.
Dave Klish, I recently ordered 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.
