In order to hang the joists I had to make plunge cuts in the two outside logs. I was not looking forward to plunging a running chainsaw tip into a log but I got the hang of it.
Once the two vertical cuts and the bottom plunge cut are made you just set a hatchet on top whack it with the backside of an axe and POP the wedge comes right out. Pretty cool.
On the center log I made saddle notches to carry the joists. I'm going to have to cut about a thousand of these before its over so this was good practice.
Joists are hung!
