Topic tags/keywords: question joining shaping sanding

Hello all. I saw a video somewhere online, maybe a year ago, that showed a table side apron attached to the leg in a certain way. I’ve drawn a diagram to show what it was, rather than try to explain it all. It was something I hadn’t seen or thought of before, as I usually see a mortise & tenon style.

My question is, with the joint shown below, how would you attach the joint once it’s in place? There was no tenon on the side, and I can’t imagine simply gluing the apron inside the leg, because the table was a large oak dining room table.

I want to try this, but I’m unsure how I’d come up with a way for it to stay. I can imagine that it held fairly well. The legs were 4×4 pine, and the side aprons were 6/4 poplar. I can’t find the video again, and it probably wouldn’t help because there wasn’t a description of how the the joint was held anyways.

Thanks all.

I would use dowel pins as well and let them be a visible design element, and perhaps a drilled and countersunk screw from the top or bottom

This is not the proper way to attach an apron.

The problems with this joint:

1. There are no shoulders on the tenon. This weakens the top of the table leg due to mortises too wide.
2. The tenon is not deep enough. The mortises should meet and the tenons cut at a 45.

The haunch at the bottom is fine.

Usually glue is enough to hold the joint together. The shoulders and cheeks of the tenon prevent racking.

Draw boring or pining increases the strength tremendously.

Many old pieces of furniture M/T joints have no glue at all – just draw bored.

I suggest you look for some other sources on the technique.

Good explanation. So if the two aprons meet at a 45, and are glued, meanwhile adding some tenon pins on the side, you think it’d work out fine?

To add: if you don’t want any pins/dowels to show, you can install them from the rear and only partially drill into the leg so they don’t go all the way through.

Not really “fine woodworking”, but you can also purchase metal brackets used on commercial tables that secure the corners and are hidden.

The table I’m doing this on would have the aprons/legs painted white anyways, so I’m not too worried.

Have your say...
