Rocket Mass Heater Workshop with Erica Wisner Tuesday June 9 and 16th, 2020 9 am - 4/5 pm
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!
OUR PROJECT: The YOME floor will be built on the gravel pad and 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.
We will be talking to Erica as well about putting 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. PLEASE NOTE: We need to act soon OR wait till the fall as Erica is a fire fighter and expects to be gone from the end of June till the end of the fire season. Acting now means that we canget more projects done - especially if we help each other! AND the projects have the summer to DRY out!
You may sign up for one or both days of the workshop.
DETAILS: SEE 'syllabus' below.
Quick Details: Time: 9:00 am - 4/5 pm. You may bring your lunch or purchase a Hub Lunch for $10.00 Snacks and drinks will be provided.
Cost: Sliding Scale 1 day : $100 - 125.00 Both days: $ 200 - 250.00 We are just trying to make enough to pay Erica for her time and expertise. We will work with you! Let us know what you can afford and how you might be able to help! Paying more- if you can- enables us to help others.
ALSO!!! We are looking for a videographer to record each day so we can offer a virtual workshop. Be our videographer and witness the workshop for free!
Virtual workshop ( both days) : $60.00 Includes all materials and books and virtual access to Q and A and email interaction with Erica.
Please sign up soon - if you can so we can move forward with this Spring workshop!
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: (June 9) 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: (June 16 ) 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.
