Did your greenhouse have a vent open, up high in your roof or side wall that was trying to be a chimney ? You may have to sneak a capped off 'T" into your Vertical Chimney to allow
you to warm up the chimney before you start your Rocket - It certainly would be cheap insurance !
You have demonstrated very clearly the difference in The skin or Surface Temperatures of the 30(?) gal Drum, verses the 55 gal drum, as both of them need to radiate off the same
amount of heat energy to create the heat differential Engine that makes the R.M.H. work, the 30(?) gal drum needs to do so at a higher Temp ! Even knowing the science, it is just
counter-intuitive enough to make seeing it so much more impressive !
Again a great job, looking forward to seeing what comes next, what are you going to do about dry wood storage now ? All the best, for the Good of the Craft ! A. L.

Don't worry, I've never met a RMH that didn't fight back a bit when starting up from cold. Now that you've got some heat in the bench it shouldn't give you any trouble until the first fire next year. A T for priming in the chimney will go a long ways to alleviating the starting pains of the first burn, but you will probably only need it once a year. Thanks for all the pictures and updates, it's been great to follow along with your build.
Matt, have you tried burning alcohol/meths? I put my wood in the J tube/bathch rocket, pour alcohol which is about 90/95° and set fire to it. Even if it draws back at first, it doesn't smoke, then gets in the right direction usualy.
Please do not atempt on a hot stove. I know what it does, and then the rocket name is there for a reason.
