I'm also interested in the shipable core business. Really, I'm interested simply creating castable cores for myself and whomever else wants one. I've started putting together a jig/mold to use with some of the "common" castable refractory stuff available around here, i.e. the Red Devil and Rutland stuff, and I'm gonna see how that works out. I think I'm going to try mixing perlite into pre-mixed refractory cement as well re: some threads on other sites about making your own kilns and forges. I'd be in the process of constructing a RMH for my house but it's doubtful, or rather, hopeful on my part that we're not going to keep this house for too long, and whereas the Wood Stove we have now is seen as a boon to the Realtors, trying to explain/sell an RMH to your average Dick and Jane buying a house just ain't gonna fly, especially were I to bypass the permitting process...
Anyway, aside from my castable project, I've been carting around a trunk load of bricks in my car lately and rigging up cores at our family and friend functions. Most of my family and friends are of similar mindset re: heating with wood, and most of us spend a considerable amount of time cutting and splitting wood, so I've built up some decent interest in RMH's already.
So, re: Ernie and Erica's designs, would you want a percentage of every core sold? Like a royalty? That would be cool. At least until things were to get off the ground, then other arrangements could be made if need be
Anyway, I have some questions about burn tunnels and heat risers, the answers are probably around here. Yup they were. So, is small scale casting, at least to start with, something that Ernie and Erica are interested in supplying a design to?
Also, I do have access to rather large kilns, but I'm going to try this out by drying and firing on my own property first.
