In theory, the bottom tips of all four legs of a table should be in the same plane so it can sit on a flat floor without wobbling. Remember, however, the words of Yogi Berra, “In theory, there is no difference between theory and practice. In practice, there is.”<\/p>\n\n\n\n

Now, if<\/strong> you made uniform leg lengths and mortise-and-tenon positions, you should have a flat base after assembly that requires no adjustment but stealth gremlins almost always prevent such perfection.\u00a0<\/p>\n\n\n\n

On the other hand, consider that rarely is a floor flat<\/strong> over the area on which the table stands, so making the four legs true is really just playing the odds. Furthermore, a table, especially a large one, may flex when you place it on the floor to produce an automatic correction. The same goes for chairs. Therefore, all of this is often of no concern at all \u2013 in practice.\u00a0<\/p>\n\n\n\n

For a small table though<\/strong>, this issue may be a significant concern. The small area of floor on which it stands may indeed be flat, the table may not flex much, and it feels creepy when it wobbles a lot. So, let’s look at how to assess this.\u00a0<\/p>\n\n\n\n

It is best to do this with the top attached<\/strong> in its final configuration, which contains any flex in the frame induced by the top piece.<\/p>\n\n\n\n

The simplest method is to put the small table on a true flat surface<\/strong> such as the table saw. If such as surface is not available, you can turn the table upside down and use winding sticks<\/strong> on the tips of the legs. Note that this may introduce error if the frame of a larger table flexes a bit differently than when it is right side up. In any case, for a larger table, I do not go hunting for a very flat floor, which probably does not exist; I just do not worry about the whole matter.<\/p>\n\n\n\n

For small tables<\/strong>, I do like to get it pretty close. You can take off the error from the one long leg, as determined by how the table pivots on the flat reference surface, but I prefer to take off half that amount from each of the two long legs.<\/p>\n\n\n\n

OK, if you have done everything just right in the shop<\/strong> and now place the table on the floor where it will live, which is not likely to be flat, and it wobbles enough to be annoying<\/strong>, what do you do? Shim it<\/a>. A layer or two or more of tape such as duct tape is just fine \u2013 in theory and in practice.<\/p>\n","protected":false},"excerpt":{"rendered":"
