Mike, I remember you shared this once before, but I forget, what exactly is this? A summer beam from something I would guess?
One thing that is not obvious from the photos I showed, that is a 2 story log cabin, with timbers the big all the way to the top. How on earth did they DO that?!
In addition to that, I know there are examples from the middle ages where building are built of timbers that were split and then hewn, and also that this method was not at all uncommon during the first half of the viking age, when their ships were built of gigantic oak. Later on this wasn't the case, as the shipbuilding boom exhausted the supply of oak. It took over 100 oak trees to build a single longship...
