my data service came back today :)
I got the singular upright members up for both the east and the west wall....
then I added bracing to the east and west uprights so I could lean against them and stand 4' off the ground (making circular saw and chainsaw cuts 7' off the plate is a bit of a stretch).
also added a cross brace on one of the 7' tripods which gives me a very large step stool 3' off the ground.
Cut up a live but storm fallen tree and dragged onsite (prbly use for platform support on south or north wall).
Next came the platform support for the loft on the east wall, three joints mean six carved cuts. Three cuts on three different uprights seven feet in the air. The other three on the single platform support log done on the sawhorses.
My method for getting the horizontal cuts on the 3 uprights seven feet in the air suuuuucked for 3D reasons easier left to diagrams. My east wall platform joints have gaps not found on my other work.
I might use two strings for the west wall to give me three cuts on three different uprights 7' off the ground whose vallies are all in line flush with each other (unless of course a half naked woman visits me in my dreams to show me an easier, quicker method).
I am thinking after I install the west wall platform support log, I'll do the east west 18' log that will set on top of the west wall member and the east wall member.
...yep, just too hot for jokes
