Almost there with the shave horse. Here are the details of the last part of the build…
The support is a 9″ wide board that is attached to the horse with a door hinge so that its angle can be changed by a movable 4″ tall wedge.

Holes were bored into the uprights and in the main part of the horse; oak dowels were inserted with a tight friction fit to act as a hinge on which the arm can pivot.

Somehow I missed the shavehorse build! Very nice work. I’ve got some similar scrap to use up, if there’s enough of it I think I’ll have a go at one myself.
