Recently I received my signed copy of Will Beemer's new book.
He shows a wedge holding in a half dovetail tie beam tenon to the post. He has cut the post to accept the wedge from the outside of the building to be covered over by the siding.

I was just wondering if it should be tapered the other was from the inside out to allow for future tapping to tighten up the joint after shrinkage.

I haven't used one of these in any of my frames and didn't know which would be best or why.

Can anyone give me any advice on this?

Thanks
Jim Rogers
