So we get things like balsa wood, classified as a 'hardwood' when it's pretty much the softest and lightest wood commercially harvested. Something one could easly drive a screwdriver through. OTOH, we can get southern yellow pine (softwood) that can get as hard as oak after it's aged and all the pitch in it has hardened. Something that would require great force in order to drive a screwdriver through.
See, it's about the seeds. Not the wood. But, hey, it was a fun game!
Indeed. I've learned several thing about woods in these comments, such as what defines the difference between the hard and soft woods, so thanks for that, Tribble. It stands to reason that there would be a formal system for measuring and grading the physical hardness of woods, and I now know what that is, too: the Janka Hardness rating.
Another good day at the Pyt!
Indeed. But far out – nice to know of all those details, particularly the unit of measurement for hardness, and the procedure for measuring it – embedding a ½” diameter steel ball into the wood to ¼”.
Now all we need is for Welch to write up a requirements specifications document, in triplicate, describing wood hardness, nail types and head diameters, methods of holding said nails, required depths of penetration; have it authorized and notarized by Mudbrooker and company; and then the test can proceed.
You said "ball"
