The ‘Janka’ wood hardness scale

[Flint62Smoothie]

I had not seen this before, although I knew such a scale existed. It would be great if we could find one of all the typical gun woods, including the woods varieties like sugar maple or such.

Anyways, I thought it was interesting and that others might like to see it too!

There is one, but I can’t remember where I’ve seen it.

Personally I think the janka scale is a rough guide. I cut and mill quite a bit of South Texas hardwoods. post oak, live oak, pecan/hickory, mesquite, ironwood all, huisatche(an Acacia), Osage orange(Bodark) to name a few. There are variances between trees in hardness within the particular species. I prefer to cut/mill green as it's much easier on tooling. When left to dry some of these species get very very hard and take a sharp cutting edge to dull very quickly. The ironwood is the hardest I machine. With a sharp edge the finish is like a polished surface.
I find wood interesting and beautiful and love working with it. There are pros cons with all species of wood. Typical gunstock wood is in the middle of the road in hardness and is a little forgiving free of knots, tight grain and abundant and inexpensive.

I score up there by the Brazilian walnut, myself……

Don't see lignum viate. It is mighty hard, should be right at the top.

The chart above is far from all inclusive. Here's the listing for it on the wood database.
