Me and Grey have been working on overhauling the rocket mass heater in the red cabin. We are replacing the barrel for a larger one, but we are not replacing the smaller riser barrel that it is sitting on top of. In order to accommodate the larger barrel, we started by removing the sand that filled the box above the burn tunnel. Then we surrounded the riser with a rock and cob wall to support the new barrel. Stephen and Caleb stepped in today to cut the lower barrel with a plasma torch to create a channel so that air does not slow down or stagnate where the larger barrel will overlap the smaller one. Tomorrow me and Grey will mix some more cob so that we can place the new barrel on and seal it in.
We started the day by mixing cob and then using it to put the finishing touches on the rocket mass heater in the red cabin. After sealing in the barrel we are allowing it to slow dry for a day or so before firing up the rmh to prevent cracking in the cob.
