That's what I thought when I saw the other.
FYI, 8oz just reaches the top of the flue tube.
The boiler is 3" by 7" and the flue is 1 3/4" in
diameter (bottom of flue about 1/2" above
bottom of boiler) and has 12 cross tubes.
When it came it was setup with a super-heating
loop, but that had to go to get this far. Cool
boiler, cool engine, happy steamer.
