// I totally agree. This notion that a guy out in his garage wobbling the table back and forth through the saddle with lapping compound is somehow going to improve the machine is just wishful thinking. The surfaces may be rough but theoretically they are accurate. As the high spots go away, so goes the precision. They are short life machines. "Lapping" in this manner makes it even shorter. The best remedy for this is dont buy them. It goes back to the manufacturing, they just to need to slow the machines down on the finish pass. ///Ron


Lapping (or scraping) the parts with respect to some master surface
known to be flat and true could make an improvement.

Why do people continue to refer to using lapping compound to accelerate
the wear as lapping?
