so in burst of aftersupper energy i carried on with cutting the last post for our sauna. however, for a variety of reasons the tenon on top of the post ended up too long, and hence the post too short. so now i am wondering what to do with it. do i cut all of the posts down the extra 1 1/4"? this will bring the shoulder of the top tenon to within 5" of the mortise for the cross beam. or can a shim be placed between the post and the plate and then matched on the corresponding post with a trim piece?

i don't have a big enough tree down and handy to replace the miscut post, which is all adzed up fancy and jowelled. so i am committed to making use of it somehow.

i'm sure i will find this funny later.
