I am making plans to build a 16x16 (plus covered entry porch) log cabin on my property in Vermont. I have decided to go with either a sawn-three-sides D-log profile OR a sawn 4 sides rectangular profile (probably 6"W10"H). The corner joinery will utilize dovetail notches with a chainsaw jig. I have seen both examples of 'zero gap' whereby each successive course of logs touches the preceding course with no chinking between OR alternatively each course maintains a healthy 1-2" gap between and is later stuffed with insulation and chinked (both sides interior and exterior?). I am using greenish (fresh sawn air dried less than 1 year) white pine. I am wondering if any experienced log builders can inform me on the advantages or disadvantages of gap vs zero gap? I would consider framing a 2x2 stud wall on the interior to increase insulating capacity. Thanks and I look forward to the discussion.
