Made this from Hedge Apple I got from my last trip to Ohio. Think some people call it Horse Apple or Iron Wood. Just enjoyed the natural yellow color, and it sure is some hard wood! Now I know why it's called Iron Wood. I use a 3/4" ball endmill for the tobacco chamber and have never had it slip in the chuck before....until this project! Shame the block I got wasn't big enough for a bent, this may be the only straight "personal pipe" that I have in my rotation. Not for sale. Gonna have to try to get a larger section of this stuff on my next trip up North, this stuff is harder than a womans head!
