This is a badge bit (BB) that is part of the PEP curriculum. Completing this BB is part of getting the wood badge in Metal Working.

For this BB, you will be making a J-Tube Rocket Mass Heater Engine (counts as two-fer with Rocket Badge)!

Minimum requirements:
- Must be a heat resistant core that is wrapped with metal for durability
- Strong enough to be moved around and handled

To document your completion of the BB, provide the photos or video (<2 min) of the following:
- The supplies you're starting with
- Partway through the build
- The finished J-Tube Rocket Mass Heater Engine

There was a great deal of metal cutting, grinding, and welding to make this 8in rocket. I needed to split the engine into 3 sections so that it could be carried by 2 people (more like 3 people). I have a ton more photos so I picked a 'partway through build' photo that focused on the metalworking.

EDIT: Is there not a separate RMH Engine BB link for the wood-level rocket (not metalworking)? In this case, I'll also attach a partway through build with a firebrick focus.

I love that Rocket Mass Heaters are Carbon-Nuetral. In Erica's and Ernies Art of Fire Presentation, Erica explains the chemistry of how that's possible!
I attended Helen's Garden Master Course in January 2022 and give the lectures 10/10 acorns! Fortunately for you, you can also see the Garden Master recordings but unfortunately you'll miss out on the fruit Helen grew and shared. It was the tastiest fruit I've ever had!

Note: Beautiful! I believe this gets your 4 metalworking points and checks off the rocket wood requirement

As if that wasn't enough, a dog then peed on the tiny ad.
