It's been rainy for the last few weeks so I haven't had to spend a lot of time running the tractor. Fortunately I always have several projects on the back-burner, waiting for the free time of winter to work on. This Barrel Rocket hybrid is one of those projects. The idea is to combine Peterberg's Batch Box with a barrel stove while simultaneously utilizing some mass to store heat and have the whole thing semi-portable. The mass will likely make the thing fairly heavy, so several people will have to move it but not nearly as "permanent" as a true RMH. I haven't taken a lot of pictures since I've been mostly in the planning stage, and I haven't completely decided how I'm going to implement the design. Here's a preview, though, of the wood feed of the stove. The first thing you'll notice is that the feed isn't rectangular as Peterberg's design calls for. Unfortunately I couldn't devise of a way to put a rectangular feed of the proper proportions inside a barrel and still build the thing robust enough to withstand transport and firing. The barrel will be laying on its side and fed like a typical barrel stove. The space between the inner barrel and outer barrel will be filled with clay/ash/sand. More pics to come. Attachments:

I did a little cutting and some welding and snapped a few more pictures...

I got a little welding done last night. Unfortunately my great grandpa's 1930s-era welder has seen it's better days and the 6011 rod was difficult to weld on such thin, rusty steel. After some shenanigans I got it tacked together, though, at least well enough to hold until I can pack it with clay-ash. The wood covering the end of the barrel is there to support the brick and clay/ash/perlite until everything dries. Once the mixture dries enough to support itself the wood will be simply burned out, hopefully leaving a nice flat back wall. I may use a single layer of brick to increase the strength of the wall for when logs inevitably get tossed against it. Attachments:

I've started to fill the "void" with clay/sand I want the mix to be good and strong for when the inner barrel eventually burns out so I got ahold of the finest sand I could locate. This was picked up from the base of a sandstone rock-face a few miles from my house. youtu.be/eRIbYmhqekwThe attached pic shows just how fine the sand is - this is a single styrofoam ball.
