Has anyone ever used boilling to strainghten yew? I'm bout to go buy the pipe, I wonder if boilling would make it more brittle than steam, or heat? Any advice on the best size for boiling pipe? I tried steam, but in cold Idaho my white gas stove, and 3 hours later, all I did was possibly damage the stave:( no more steam for me. It's obvious when water boils, and the temp is therefore correct:)
