Installing window frames in a log cabin

How I install window frames in my LHBA Butt & Pass log home. These frames are made from 4x16 lumber I milled from a tree on my property. They are very heavy - probably 300 lbs - and are lag bolted at the top and bottom with 1/2"x8" lag screws. The window is 3x3. I use a chainsaw mill and 2x lumber to get a straight cut through the logs, then carefully cut around the rebar pins. When not cutting all the way through a log (at top or bottom), I start by removing enough log material, then I can usually knock out the excess with a hammer. Finer pieces require a chisel. For the cuts that go all the way through a log, I belay the log with pulleys so it doesn't bust a hole through the floor when it falls. They can weigh a few hundred pounds. I make the hole about an inch or so bigger on all sides, making it easier to chink later - less than 1" is hard to chink. Set the frame in place, level it and temporarily set the window with just a few screws (I'm using 1/2"x10" lag screws here). Later (not shown) I'll square up the frame by tightening the screws in the side of the frame, shim the window, then add trim and spray foam, and then more trim. And that's it. Note: in an LHBA style home, false headers or space above the window is not required because an LHBA log home doesn't settle.
