So I’m partway into this coffee table and looking for a little structural advice. The aprons connect to the leg with mortise and tenons (but haven’t been glued yet). The first question is if I need some corner bracing like a piece cut at a 45 in each corner (and if so how to connect that to the aprons). The second question is about a center brace/stretcher. One of the longer aprons (54”) has developed a pretty serious curve. If I connected it to a center stretcher, that should straighten it right? And how to connect that?

My first hardwood table project so help is appreciated!

I give it a try.

45 corners , use a wood block and you can put a hanger bolt on to keep the leg tight. Screw them into the aprons.

Twisted apron. If you put in a dovetailed center stretcher, it may relive the torsion in the wood, it may make it worse.

If the apron is twisting now, I would consider a remake. Sorry. Or mill some shallow cuts on the back side, clamp it flat and fill with thick epoxy, then edge band the lower edge.

Keep us updated on what you did.

if the joinery is done right, you don’t really need a corner brace, but if you want, it will add more rigidity. screwing those on (no glue) would probably be best.

as for center brace – a sliding dovetail would be the way to go, then once aprons are in legs, simply slide it into the 2 aprons to keep them inline. as mentioned above -this would be a good option if your apron is bowing or cupping, but if you have a twist then this may not resolve everything and you could potentially still end up with an unsquare/unflat table.
