Timber Framers Guild Forums General Barns and Traditional Timberframing Pegs -- riven, sawn, drawn, turned, driven, etc?

that's a cool video -- really neat to see it in action.

So these turned trunnels are for transfering shear when you need to have no slop in the connection? Makes sense. I'll have to go to the local bridges and see what sort of pins/pegs/trunnels they have. All the local surviving bridges are lattice, so plenty of trunnels in them.
