Problem with table legs and apron

A twist/bow in the apron could cause this. If it is not bad just sand/trim one of the two legs that don't rock until it stops rocking. I would perform this adjustment after the top is attached because it might pull everything straight once screwed down.

Easiest solution, if your leg style allows it, is to sand a bit off the longer leg(s). If you're dealing with a decorative foot and can't remove any material from the bottom, then I suppose you'll have to shorten the leg from the top and reassemble.

As a rookie tablemaker myself, I find that the slightest bit of difference in leg length, or racking of the apron, translates into a very wobbly table. It's probably best to clamp the legs on an test before final assembly.

Next time clamp well, then assemble/glue/screw with the table in the upright postion on a _level_ surface.

Two options: make the long leg(s) short, or the short leg(s) longer.

If it's only a small adjustment, taping sandpaper to a flat surface under the offending leg(s) and moving the table back and forth until it stops rocking will often work.

You can also glue a shim of the same material, shaped to fit the leg contour, to the bottom of an offending short leg. If you round-over the edges of your table legs at the bottom, which you should do, you can generally get away with this fix being invisible.

One additional way.

Install some furniture glides on the bottom of the legs with some S/S sheet metal screws, then insert S/S fender washers on the short leg between glide and leg using screw to keep in place.

As all Tool engineers know it takes three locator points to create a plane. That any additional points fall into that plane is pure luck. But we always want to put four legs on everything.

establish which three legs you want to be your plane, then shim or trim the fourth, whichever the case may be.

Ever see "That 70's Show"?

The show had a funny bit once where Red fixed a wobbly kitchen table, with the table ending up at coffee table height.

Darrin,

I built a table once that didn't rock until 'after' I attached the top! Try putting the top on, it 'might' tweak things into place.

If it doesn't remove the top and 'gradually' shorten the longest leg by rubbing with sandpaper/wood block a little at a time.

One more thing. Are you sure the floor you have the table on is completely flat?
