Topic tags/keywords: table legs table top joining modern question threaded insert internal hex bolt

I’ve been building table with 20 degrees angle legs and I was planning to attach the legs with internal hex flat head bolts through the top and threaded inserts on the legs. Unfortunately the red hard wood (massaranduba) I used breaks very badly when I try to insert a threaded insert so I gave up that idea.
I am looking from some advise/ideas how can I attach those legs.
Please look on the two sketches to have an idea of what I am trying to do.
Thank you.

Sliding dovetail perhaps? Check out how this top is attached, it’s a beautiful method. https://www.youtube.com/watch?v=x51zMg7roIs

Another option is to drill a 3/4 inch hole about 1 inch deep and glue or epoxy a hardwood dowel in the hole. Then you can drill and insert the threaded insert in that softer wood.

ChefHDAN thank you for the link and for taking the time to answer me…!!!
Yes it’s a nice method but it won’t work for me at this point as it’s a folding leaf table and legs are attached on the leafs and the dovetail cut will show when folded… but it is one strong way of doing it… even though I might consider it.
Thanx

Another option would be to use tee-nuts that you install with brads (not the barbed ones) instead of the threaded inserts.

HokieKen thank you for the idea but the only ones I can get are the barbed ones, but I may try to cut the barbed points and drill 3 holes, that might work … Thank you for the advise !!!

Drill an over-sized hole and epoxy in your threaded inserts?

To keep the internal threads clean, coat a bolt with Vaseline and thread it into the insert while the epoxy sets.

I would use mortise and tenons if it were my design. But since you have likely already cut the legs to length, it is too late for tenons. In this situation I would opt for loose tenons.

bondogaposis wanted a mechanical fastening method as the legs are not stationed but attached to the drop leaf sides thus folding with them, thats why didnt use mortise and tenons although I used them to connect the triangular top part of the leg… thank you :)

Why do you need to bolt the legs on?

papadan because are movable folding leaf legs and 1 inch thick only so i believe a through the top fastening will be stronger
