Hello Kyak Jack,
My friend Keith asked that I post a few pictures on building a dugout. Here goes.........
First find a suitable log, for us this means pulling up an old sinker cypress
Get it cut into a cant, be careful to avoid the very center and any shakes
Outline the top of the dugout based on the shape of the cant and cut to that shape
Turn the cant over and outline the bottom
Now trim away anything between the top outline and bottom outline that doesn't look like a dugout
Do whatever additional shaping to get the lines you want. Remember this is all by hand and by eye.
With the outside shaped, hog out the middle
This hole is key to making a dugout from a wet log as it allows moisture to leave the log without splitting the ends
Continue to remove any wood that you think doesn't belong and you'll eventually have something that'll let you run your traplines
