The second generation shop is going being built, probably be up and running in about two more months. Then the rocket stove monotube boiler begins. I haven't done enough research ...never enough I suppose and yet I have a definate idea about what I'm going to do... Screw it, it's go time!. Where ignorance resides, I will simply make an adjustable everything. The deviation from rocket stove design is that I will be using a modified type of riser. It will be elongated ...(rectangular) rather then tubeular. The reason for this rout is that I will be using off the shelf, screw-together piping in a hairpin configuration. I will be using extreemly low pressure steam and supplying a large 12" x 11" double acting steam engine. Not effecient, but durable and easy on gaskets and packing...what ever. More about that later.
Pipes will be arranged on top of and outside of the riser and dump into an outside circulation drum. Don't expect anything solid for the next two but then, .....stay tuned.
