Question if hand-sanding is really that much better nowadays. I've seen walls done with good electric sanders that look perfect after painting. The time saved seems worth it, and most people won't notice a difference once the primer goes on. What kind of jobs make you stick to hand work?

Yeah, a clean setup really does change everything. The big trick is just keeping that water fresh and skimmed, plus having a solid lid to keep forge scale and other junk from falling in when it’s not in use. Placing the tub where you won’t trip over it is half the battle won right there.

Those daily teasers are just marketing, right?

So, when you say thin air affects the burn, is it mostly about oxygen levels or does the fuel not turn into gas as well? I've heard that liquid fuel stoves like WhisperLites can be set for altitude, but canister stoves just lose pressure. Did you try warming the canister or something to keep it going? What was the exact setup when it failed?
