Rocket Mass Heater Workshop with Erica Wisner 2 day workshop coming late September / Early October
Building a Rocket Mass Heater warmed COB FLOOR for the YOME that will go here.
This workshop offers an excellent opportunity to learn the how-tos of building a rocket mass stove and how to work with cob with a Fire Master!
SEE The YOME floor Juliane will build on the gravel pad. It will hold the exhaust pipes for the stove. In this way the cob will be heated and slowly release the heat into the yome. Rocket stoves require less fuel due to the design - which promotes very efficient combustion.
OUR Fall PROJECT: We are planning to put a Rocket Mass Heater in our double wide mobile - with a bench and/or masonry heater.
We are also planning to build a double chamber cob oven - to utilize rocket stove technology in a cob oven. (Our vision is that the Cob oven will become a community opportunity to have pizza parties, bake our breads and cook soup, beans, grains, roasts together on a regular basis)
You will get hands-on experience with the whole process as well as the opportunity to learn from Erica. Each day will include a Q and A session so you can get her input on your project. Erica will also provide access to teaching videos as part of the package.
Syllabus/ each day's events - exact activities "subject to site specific details, weather, and other realities."
Pre-Course Fire Science Primer: All course participants (hands-on and virtual) will receive pre-course materials to watch, read, and play with; and in-course documentation including photos, videos, and diagrams. We encourage watching the "Fire Science Theater" video and/or reading "The Art of Fire" booklet before Day 1, and reviewing the rocket mass heater diagrams provided.
Hands-on participants will be part of the team for one or both of the work days (below). Virtual participants will not be physically present, but will receive study materials, photo and video updates, and will be able to ask questions and participate in the whole-group Q&A sessions by phone, text, or Zoom. (Virtual participants could also include people who don't have weekdays free, but may be able to stop by the site at other times during the build by arrangement.)
Day 1: 9:00am: Coffee and Introductions 9:30AM: Course start Layout and First Steps:- Introduce and orient group to project site, plans, facilities, location of building site, tools, and materials. 10:30-12:30- Skill Stations: earthen building materials (cob/mortars), brick layup, chimney connections. Rotate/review mid-morning. LUNCH & cleanup 1:30-3:30- Skill stations: lay up firebox, chimney and ducting layout, prepare/check barrel fit and manifold/plinth. Tool Rodeo (cleanup) 4:00-5:00: Review project progress, Q&A for all participants (hands-on and virtual).
Dinner Bonus Session 5-6:30 pm: Over takeout/box dinner: review clearances, thicknesses, and other design rules with participants, particularly useful for those looking to build in their own space soon. Possible campfire / brick stove cook-off, if weather and interest favor.
Possible bonus work party - Site hosts may use the gap between days in this format to bring all parts of the project up to "cooking show" status, prep materials, and be ready for a rapid finish on the last day. Virtual participants may be able to get some hands-on time without the crowd by arrangement.
Day 2: 9:00am: Coffee and Introductions 9:30AM: Course start Orient new participants, review state of project, introduce teams for skill stations. 10:00-12:00- Skill Stations: Cob layup, finish brick layup, check firebox & manifold, insulate heat riser. New participants may practice with brick layup demo station. 12:00-12:30: Whole group review project progress - are we on track for functional completion today? LUNCH & cleanup 1:30-3:30- Skill stations: Finish manifold/plinth, bring bench to sub-finish height, prepare mortars/plasters. 3:45 Whole group together for barrel placement. Demonstrate finish plasters as time allows. 4:00-5:00: Whole group together for test firing, review project progress, Q&A for all participants (hands-on and virtual). Tool Rodeo (cleanup)
Day 2 Dinner Bonus Session 5:30-7pm: Box dinner, participant design share. All participants are welcome to bring/submit their own project ideas for review at this time. Small groups with similar interests will work together on selected designs (for example we might split into a greenhouse heater group, a tiny house group, and a larger house/barn group). Then the whole group will look at each design (either by presentation, or by rotating stations, depending.). Larger paper or chalkboard presentation formats are encouraged, to allow full participation with good social distancing. Virtual participants are encouraged to drop off printed or sketched designs off before the session, and participate by phone or Zoom.
