One of the few cool things we got to do during the Great Covid Shutdown was a visit to TinMan to upgrade the CottageRocket we built for him back in 2017.

Please note the completely trashed high temp stainless steel pipe we thought we could line the inside of the heat riser with. Metal doesn't belong in the innards of a high-functioning rocket heater.
