While the extrapolated results of the past have proven to be on target with reality, reality beats extrapolation hands-down every time. In recent years, a number of testing results have now been carried out and published for specific conditions of pegged joinery.
However, nothing ever beats a direct test for a specific condition, as the results end with an emphatic exclamation point. Therefore, it is possible to extrapolate from the results of one test the critical information that may reasonably be assumed to apply to a different, albeit similar, condition.
This is common in engineering, because the essential physical laws concerning force and motion, primarily Newtonian physics, are symmetrical. The corollaries that could be made were drawn from testing results for bolted connections. When this book was first written, there did not exist any scientific testing results for pegged mortise and tenon joinery. At last, it was published for general distribution in 1998.

Over a period of a number of years several revisions and additions took place, as it was used as the handout workshop manual for Fox Maple Timber Framing Workshops. The major portion of A Timber Framer's Workshop was first written back in 1983.
