tenons with hollow legs

I usually just use mortise and tenon construction with hollow legs. I like locking miter joints better than simple miters because they are easier to assemble.

Thanks for the quick response, nice tree in your yard. You wouldn’t believe how much googling I have done to find a picture like the one you posted, thank you.

Let me ask a really dumb question, the way you have this setup how deep do you make the tenons? I am assuming just slightly deeper than the leg stock? Its quite a long table do you think there will be any support issues with having it open on top like that? Table is about 86” long 122” extended. If not this would greatly simplify my approach.

Cool, Willie is the master so I would probably follow his lead. However, in my uneducated past, I made the legs as you have and then glued a block into the center of the legs to receive the tenons. I was concerned about wood movement, so I made the blocks a bit narrower than the cavity. They can be full length or just added in where needed, plus a few inches length to assure a good glue bond.

My current method is to laminate a substrate with lesser wood (same species, but little to no figure) and veneer all 4 sides (see pix 2-5). This eliminates the hollow issue and is a good use for plain stock. FWIW
