Thank you for your input. This is a long term project/goal for me, I am not in a rush to get the building built and would rather learn the craft the long/traditional/correct way.
I would classify myself as someone who does not frustrate very easily and has a lot of patience. With that said, I plan on learning in small, incremental steps. Due to the fact that such work is skill and labor intensive I am looking to learn the hewing and the framing simultaneously rather then sequentially; so I am planning on doing some TF work on cut timbers just to get the technique down first while I actually cut and hew the timbers.
I saw on the Whipple Tree site several of the workshop projects were small assemblies just to get the basics of the joinery.
I appreciate the recommendation of the Sobon shed. I will look into that.
