A missing “tab” character on page 56 of “The Essential Woodworker” garbled the chart that showed rough sizes and planed sizes in inches and millimeters.
While all the numbers are correct in the chart, the labels on each column were shifted because of the missing tab. The corrected chart is shown above. Also, you can download a high-resolution version of the corrected page below, print it out and stick it on page 56 if you like.
Our apologies for the mistake.
