Wonderful work. I am very happy to see a "squared" bastion in the corner, instead of a quick 90 degree turn. Visually, it is much more interesting with the extension and more accurate.
And a brand new blockhouse. Or at least, I do not remember seeing it before.
With your blockhouse, how do you make the joint? What tool are you using? The cuts are wonderfully precise and they have the proper alignment. The few times I have tried, my cuts are awkward and out-of-alignment with each other --- making them useless for building anything.
Do each of the log you place have 4 joint positions like a "lincoln" log, or just 2?
