It's a bit messy, and probably not nature friendly, but had a neighbor just burn his diaphragm out by burning firewood in it for several hours. Black smoke... ugh.
Awesome job, the barstools are cool as well!
I actually bought them 6-8 years ago from homedepot.com I don't believe they stock them anymore but still have several other models available if you do a search for bamboo barstool that come up.
Looks great! Thanks for sharing
