This is the first floor system being built. The floor joists are I joists, they are flat and come in long lengths, some of these are 48' long.
The frame of an insulated log home is basically the same as for a conventional framed home. This home had 2x6 walls with R-19 insulation, a 1" layer of polyisocyanurate foam with 1/2 logs inside and out. The completed wall assembly is approximately R-30.
This home had vertical logs in the corners. The 16" Makita circular saw is being shown cutting the 90* notch out of the corner post for it to fit on the house corner.
A Prazi beam saw can be used to make cuts as deep as 12"
Logs are then attached horizontally between either corner posts or window and door trim.
These 1/2 logs were stained prior to cutting with the freshly cut ends being stained prior to attaching to the wall.
10" Olylog screws were used to attach one course of 8" log siding to the course below. 6" Oly's were run into the framing at a 45* angle.

A slick is a long handled chisel that is never struck but is pushed through the wood and acts much like a plane.
I started the logs so that a full log would pass over the windows and doors. There are many ways to trim windows and doors, this is one.
The log siding on the dormers rests on a cedar 2x2 strip between the logs and the roof. Step shingle flashing is interwoven with the shingles and behind the 2x2 and siding.
This corner log also formed the trim for the kitchen sink corner windows.
