Not sure if any will see this being 3 years old. I’ll ad to this if anyone comments. I’ve made pipes for 50+ years and I’ve seen it all. No wood pipe is safe if you light it with a blow torch. My pipes are smaller with shallow bows. I make small one person pipes.
Pipe style I started making 6 years ago and made a few hundred. I have parts to make dozens of these pipes if anyone is interested. I’m in the north west part of Vermont
