    Great guide

    With the explanation on the website, even when the wood I wanted to use (wenge in one case) wasn't listed, it was easy to google the coefficients, use the formula, and figure out how much I needed to allow for wood movement here in Calgary. For the great price of free too!

    Much Needed Workshop Tool

    After several minutes of familiarizing myself with the data, I applied it to my latest project built during winter and forecasting wood movement midsummer and pleased to learn it is minimal. Very easily accommodated with threaded inserts in oversized holes. My only wish is that it had curly maple listed, but used the others listed similar hardness.

    Love this handy chart

    This simple chart is really handy for determining the space needed for expansion/contraction of your projects. And it's free?

    Clear and well researched

    Very handy piece of work - takes a lot of the unpredictability out of working with wood.
