JPZ66 Posted February 11, 2014 Share #4 Posted February 11, 2014 Not being familiar with the Janka Hardness scale, I looked up the definition which helped me to understand the numbers a bit better..... Wood Hardness What is Janka Hardness? The Janka hardness test measures the force (in pounds-force) required to embed a .444 inch steel ball into a piece of wood up to half of the steel ball's diameter. It is an excellent measure of how well the wood withstands wear and denting. For example, Verawood has a Janka hardness of 4500. This means that 4500 lbs-force (2 1/4 tons) is required to embed that .444 steel ball into the surface of the Verawood until half of the steel ball's diameter is in the wood. This tells you that Verawood is incredibly hard. Google "Janka Hardness" for more information. Cheers, Joe janos 1 Quote Link to comment Share on other sites More sharing options...

Gaetan Bordeleau Posted February 13, 2014 Share #6 Posted February 13, 2014 Density is a more helpful factor to help to choose wood species. I did this about 20 years ago: We all agree that boxwood is very good for detailed scluptures, but may be some other species from South America could produce crisp edges...
