I have a question on how the cruck blades were sawn? Were the curves on the blades sawn with a bandsaw? It looks like it rained a little.
On the 3rd picture, or so, you can see the two tenons, the post tenon and cruck tenon, it doesn't look like too much of either was compromised. Ken, are you asking Dave why the post doesn't set on top/back side of the cruck and not go all the way to the sill? That is the way my posts land, They don't sit on the sill. Did the instructors give options?
Ken, what do you see as the typical configuration in your part of the world?
