Of all woods besides Mediterranean briar I think Osage Orange has to be the best choice.
Native Americans ate the seeds year round for Vitamin C, they made all their good bows from it, and I won’t allow any other kind of corner post on my farm be set but an Osage Orange, commonly known as hedge, or Bois D’Ark.
I had a machinist friend who used Osage Orange to turn replacement bearings for slow moving machines, instead of Babbitt metal.
And, many others have already turned pipes from it.
The disadvantages of Osage Orange for pipes, is that it’s plain, and will have some tiny pores that won’t work out.
The advantage of Osage Orange is that it’s about the densest, hardest and toughest wood I know of, it’s not poisonous, and full of sweet tasting resins and saps.
