The foundation construction continues now with real Pressure Treated posts.

So, as I found out, the Pressure Treated posts I bought for less were treated to "refusal". In other words, not pressure treated enough to be useful in foundation construction. I went out and bought the real PT posts-- 6x6x10. $100 lighter, at least I had the right posts. For one, they're a lot heavier-- probably due to water/chemical content. Also, when cut, they don't break. Unless cut all the way through, the fibers can't be twist-broken. They need to be cut.

One more change to my design is initially, I was going to have the 6x6 posts at each pier. But to accommodate the height of the posts, I would have had the sauna floor beams sit too high in the air. What I changed is I'll have the highest pier be the location of what the beam sits on. The rest of the piers will have posts to level with the first pier. So, for my highest pier, I used a 4x4 Simpson bracket which will take the (2) 2x10 beams. The rest of the piers will have the notched posts accept the beams. At least that's the plan.

So, now that I had the right posts and lowered my string and re-leveled it again, I was ready to cut my new posts to the new heights.

Using a string level, I was able to find a level plane and match the posts to it.

Once the posts were cut and all level, I got back to notching. I was concerned with that part. I've read online different suggestions on how it's done. Some suggested Sawzall, some chainsaw. I tried a 7.25" circular saw-- but oddly enough, it's cutting depth is like 2.5" or less. The post is at least 5.5"-- that'd leave me with 1/2".

First attempt at notching support posts was unsuccessful.

In the end, I came up with a method that worked best for me.
