Thanks for the great resource! I guess this is sorta an intro and a question wrapped-up in one!

I am building an outbuilding (workshop/wife escape) on an historic site. (not regulated by historic rules). It's two stories. I hope to timber-frame the top story.

The bottom level, I have framed-up with rough-sawn hemlock 2x6's (a full 2" x 6"). I've designed pockets to hold two 6x6 oak posts that will sit on top of the block wall and mortise and tenon into a 12x12 beam that will span the length of the building with a post in the center that will sit on a 3" deep concrete slab that's already poured.

The framing (with a temporary brace and spacer where the beam will go). The top plate is not yet on the walls either.


This is a shot of the twin 6x6's in place. (boy, I sure need to get a beam saw!)

and a close-up of the tenons...they are 2" x 6" and have are 2" from the end of the 12x12 beam end.


I intend to run locust pegs into the posts, through the hemlock studs, deep enough to go partially into the sister 6x6 post. Then, once the beam is in place, I'll run them into the tenons as well.

This is just sorta an attempt to get a little experience in the timber-framing methods. I hope to do the whole top floor with TF.

Do you experienced folks see any flaws in this design? I've probably give it TOO much thought! crazy

Just another quick note: this site had a structure on it circa 1860. I've done what I could to restore/renovate it, including restoring a stone wall. How the craziness began:

The original wall:


The wall after I spent months of chiseling, remortaring, and blasting with glass beads/baking soda:

Welcome LTC!
The shot of your posts if from the outside of the building. I cannot tell if you have mortises for braces. Are you going to brace from post to beam?

p.s good looking wall.

No braces...I was just planning to mortise the beam the the top of the pair of 6x6's posts that are built into the wall then peg it.

The beam in the center of the building is a the same size as the long main bean, so I was just intending to mortise that into the beam as well.

Is there a better idea?

Whoops...just re-read the last post (and couldn't find a button to edit it).
The support POST in the center of the building is the same size as the long main beam.

Welcome to the forum,

"a three inch concrete slab" for your post sounds thin to me.
I would pour at least 8 inches thick under a post and somewhere around 24x24.
I assume the "close up of the tenons" is taken from the outside of the building?

What are the dimensions of your building?

Whoops. I need to proof-read better...
The footer for the post is almost 3 FEET thick, not 3 inches. ;-)
I know it's overkill, but had extra concrete left over from another part.

The building is 33.5' x 24".

Yes, the photos of the two outside posts are from the outside of the building. The tenons are 2" thick, 4" wide and 6" deep. The shoulder of the tenon is 2" per side. They are going into each end of the main beam.

The beam is an actual 10x12. It was sawed yesterday. We'd hoped to yield a 12x12 but the log wouldn't give it.

Here it is (with a few 5/4 boards on top of it):

The post for the center is here:

It too is a 10x12 and will be placed right in the center with a big M&T joint and pegged. Should it get a knee brace?

One more thing, other than the obvious (a crane). What's a reasonable method to get this lifted-up into place?
Thanks!!

I don't know how reasonable it is but it could work. Put it on a timber cart and wheel it inside.

I think I could move it inside, but it's getting it on top of the wall that challenges me.
