(I've had this open in a browser tab for a few days' and I don't recall where I found it. If you're the originator, let me know.)
The Alaska Trappers Association has a good short video on log cabin building. It seems that chainsaws make it go much faster. :-) A shed rood rather than gable roof would save time if you were in a hurry, and if you had access to a brace and bit or a drill, you could use pegs and omit the spikes.
Of course, there are a lot of gaps in the video where I suppose they go into details about squaring without a square, doors and windows and so on. I'd love to see how they handle these. Here's hoping they put the full course on-line in the future.
