For those in the UK who want to build this stove, here is a bin of the right size for the outer. Only problem is the lid as I see it. Right! The only thing you have to do is turn the bin upside down. By that way, the bottom side is open but it's necessary to cut that out so there will be no problem. |

I hadn't noticed that, I can see now here. does this still allow the exhaust to go through the chimney, and not just out next to the pot? If I don't need a lid, I can use a straight sided drum, but they are £25 each.  |

I hadn't noticed that, I can see now here. does this still allow the exhaust to go through the chimney, and not just out next to the pot? It's best to place the stove on even ground. But it still would work the right way even when the bottom is partly open to the outside air. See the picture of the test run, the small bench underneath is not fully closed. The only effect is a lower temp of the exhaust stack. The pot has to have a very tight tolerance compared to its opening in the top of the drum. It's entirely possible to use a second hand oil drum, placed upside down. The then bottom end cut open leaving a 1 1/2" wide ring of it, a hole cut in the top about 3/4" smaller than the pot, and a 3/8" flange bent and hammered down all around the opening to accommodate the pot. It's important to have right-angled flanges at every opening to retain stiffness. |

.............. a 3/8" flange bent and hammered down all around the opening to accommodate the pot. That would be relatively easy to do in a flat piece, but in a drum I think it might wake up the neighbours. |

Patrico do over the counter sales with no minimum order at their factory in Tewkesbury - but phone to check they have items in stock first. Also their 110 litre bags of vermiculite are £10.80 +VAT. Jewsons gave me the same price but that was for 100 litre bag. Not sure where you are in the UK. I'm in Bristol. Going up to Birmingham next week so intend to call in to get some drums etc. I can pick some stuff up for you if you're local(ish). |

Morticcio, I would be very interested in that offer. I am based in Abergavenny, so not far from bristol and I will be in Bristol a couple of times in march. I'm interested in the red one in this picture www.patrico.co.uk/open-top-steel-drums-kegs.html , the relative dimensions look perfect for what I need, but its hard to get an idea of the actual size, and any idea of their prices?

You are right, they don't have a minimum order charge, but the difference between 1 off and 10 off is significant. e.g. 25 litre 10 is £8.10 each, for 2 is £18.10 each. Similarly the 10 and 20 litre cost £10 each extra if you have two instead of 10. I'm a bit west of Cambridge, so way off your route. Patrico charge £25 for carriage so cheaper than a visit. The nearest size I can see for the outer which is 60 litre is from www.gardentrading.co.uk and is their part DUGA01. They are available for around £25 and upwards depending on who raids your pocket. Patrico do a 14" dia 23" tall open top drum with parallel sides that would do at £25 each for 2. |

A supply update. Amazon have various buckets on their site made by "Wilai GmbH". If you use that as the search term you can see lots of options. Sizes range from 10 L to 60 L and they quote quantities of 5 and 10 if you need a few. Typically the cost of 10 halves the unit price, and shipping is reasonable. I have used similar sized buckets to make sawdust stoves, but only single skin. I think with 60L 25L and 12L it would be possible to make two sizes of stoves, and their life could be extended by spraying with high temperature exhaust paint.

Here in the states while looking for metal buckets of these sizes I concluded that cheap thin skinned stock pots were easy to find.
My current build uses part of a water heater tank, but they are harder to get /more expensive.

The 60L was delivered today, as were the 12 and 30 L buckets, only they went back to the depot as no one was in to sign for them.  The 60L cost more than 50 GBP, but heigh-ho, I will soon have a small institutional stove so who cares.  . I will try and get some 18swg 310 stainless to make the combustion chamber, though it might be a bit expensive for occasional use stove, and some 304 or 316 might do just as well. The 310 would be justified if I had done lots of testing to establish the optimum size, but that's never going to happen. Wildstoves used to sell a clay combustion chamber for rocket stoves,but its no longer on their website. 60L part no 23021 30L part no 23013 12L part no 23012 |
