Through tenon wood expansion

[Patrick Walsh]

I agree, nice design.

I might have to make one, I have a perfect spot. And a bungalow...

I wouldn’t worry one bit about it.

Thank you Andrew and Patrick. I guess since it’s the highest humidity right now, I’ll go snug.

You could also make the through portion of the tenon narrower, and let the rest of it be blind. Then you can allow some expansion gaps on either side of the blind tenon.
