I would like to build one of these. Though not too difficult, do you have any pictures of how the bricks are stacked inside?

I don't have any pictures, sorry about that. All the bricks are in an upright position standing on the shortest end, flat against the inside face of the barrel. All bricks are angled on two longest sides as well and stacked carefully so they won't be able to fall out of their respective rows. It's quite some work, but this way a maximum of weight can be added without compromising the bell effect too much. With the assistance of a wet saw specifically for bricks we managed to complete it in a little more than half a day.

Maybe I wasn't clear about this, the bricks inside the barrel are just normal building bricks, no refractory at all. So this is much, much cheaper than fire bricks or castable refractory.

Thank you, that has just saved me more than £150 for the bricks. 🙂
Is the small hole behind the feed hole an air supply hole?

Yes, it is. The air is fed into a built-in P-channel, cooling the top of the feed at the same time. The core inside is a 4" Dragon Heaters one, see www.dragonheaters.com/.

A Dragon core would be nice, but as I live in the UK the shipping will be large. I will make one of the cores described by Matthew Walker using CFB and some 1” thick firebricks to form the feed. With some care I can form a tripwire in the tunnel then add some fillets in the corners to hopefully improve the gas flow. I can glue these in with Fraxfil which you probobly know of. I use it for sealing boilers and flues as it stays flexible and is easily removed for maintenance and repair. Also being a waterbased based, is as eco friendly as any available.

Not ordinary house bricks either 🤫. The second picture looks good with lots of surface to get the heat into the (luxury) firebricks.
