So based on this recent observation, and without the benefit of further study (hence why you should take this with a grain of salt) I'd suggest that perhaps you aren't getting the mix wet enough to allow the clay in it to be it's full sticky self making good bonds to all the other materials.

You could perhaps get fire stove gasket to embed around the barrel where it meets the cob to create a thermal transition to prevent the cob from cracking.

These are just ideas, and maybe you’re not into that much fussing around (and maybe they won’t work anyway) but that’s what I’d start with if I were looking to finish a baby dragon and make her lovely.
Are you doing straight fire clay and sand?

I'm very keen on reducing the amount of body strength and testosterone required to prepare firewood
as I would like to see systems that anyone from a 7-year-old to an 70-year-old (i hope) can do without too much stress or danger.
The great thing about RMH is that the wood from the waste stream (be it from construction timbers or the tree waste (too small to burn in a box heater) from cordwood operations)
is perfectly suited to burning in an RMH with minimal splitting work required.

My tip for easy cutting of smaller wood, maybe 1 to 1.5 inches in diameter is a nice pair of loppers. I got mine a few years ago for yard work and love them. With my new RMH I'm thinking I may start hunting for some with even more leverage so I can cut larger diameters. I would greatly enjoy being able to cut my "firewood" with what are essentially a big pair of scissors!
My new pebble style RMH has been doing fairly well, though I must admit it's not as efficient as I had hoped for. I'm only using about half the wood I used to, which still isn't bad. I was hoping for better though I knew I couldn't get it as efficient as it could be due to a lack of space for the heat exchange bench. You mention that you can run yours for a few hours in the evening and still have the bench warm in the morning. Can I ask, with your cob style in the few hours you burn does the bench heat up to where it physically feels warm to the touch, ie not just room temp? Does it still feel warm like that in the morning? Mine will heat to where the top surface is 80 to 90 degrees F after a several hour burn. I feel like it should be doing better and wonder if cob is that much different?

Are you using a tire bolted to your chopping block ? Best way ever to hand split!

Next I'll have to tell you about alternative energy... Keep those lights burning while your neighbors sit with candles.
Mark Tudor wrote:Mention of 3 inch pieces though, why split those at all? Once you get a few smaller pieces going hot you can drop 1 or 2 pieces at 3 inch thickness in and you are set for a while right? I'm hoping so as my goal is to grow an acre or two of coppice to rotate through, cutting it at around 3 inches so I don't have to split it, just cut it at 15 inch lengths and it's done. But maybe that won't work, I haven't given it a try.
