|Centering the top on its base used to be a time-consuming
process for me. I'd spend a lot of time with a ruler checking and rechecking the
overhang along all four sides to make sure it was the same all the way around.
But now I use a quicker method that's more accurate.
First, I flip the top of the table or cabinet upside down and mark the center
of all four sides, as shown in the drawing. Then I find the center of each apron
(or side), making a mark on the outside face of each one where it meets the top.
Once the centers are marked, place the base upside down on the table top.
