Thanks a lot Peter. Nice of you to have put the power in KW. I understand that better than the BTU.

Hello, I encounter some problems with shipping in my Island. I've been in Europe last month and my parents want to build something to heat their house (living room and office), they have a very beautiful but not very efficient fireplace. We thought rebuild the chimney and build a double bell in a 70 x 200 X 220 cm volume heating on both sides My mother wants a panorama ! Here is my first sketch for a lateral-panorama-horizontal rocket. Sketchup link  |

@(sata)Max,
From another post, I'd understand you are using your batch box stove in your flat at the moment. Could you elaborate about the results, accompanied by some pictures and even a video or two? Please?

I need to clean the paint, and with that bleemin oven cured epoxy, i'm getting nowhere. I have to get a quote for sandblasting it. I've tried a mixtuire of flour, amonia and caustic soda, and it doesn't strip the paint! |

New to all this but learning quickly, cannot open your skp file no matter how much junk I download to the mac to convert it or view it, is there any other format you can post it in please?
I don't quite grasp the "I think the combination of the siphon, tripwire brick and channel are the winners here" being from an automotive bent I can reason that the channel is an air jet where the narrower bricks bring the fire box into a venturi but do not understand the concepts behind siphon and tripwire brick or where they are situated. Can you please point me to the info I need to get my head around this.
Many thanks, David, Ireland.

mustaffatap, You gotta read through some threads, mate. Small scale development thread which introduces the tripwire and peter channel/plate The siphon concept is in the Rocket bell project thread. Both of these threads should be required reading here.. It's why they're sticky.  |

Sticky, now there's another concept I didn't understand. Thanks for that Donk, great info so far and kindly written which makes a change. Will get my specs on....

Dear Schwarze Peter, sorry, i don't use it yet. I need to clean the paint, and with that bleemin oven cured epoxy, i'm getting nowhere. I have to get a quote for sandblasting it. I've tried a mixtuire of flour, amonia and caustic soda, and it doesn't strip the paint! You can use an angle grinder with a sand-paper wheel.. And, I hate to say it but... I've had best results by burning the paint off. It's a toxic nightmare, but it sure works. I make the 55 gal. drum into an 8 inch "pocket rocket", get it burning (with wood) really well, then pour in waste veggie oil. It gets STUPID hot, the whole barrel glows cherry red, and sends up a massive toxic cloud as the paint burns off. My conscience screams at me every time I do it, and every time, I try to rationalize it away, attempting to convince myself it's in the name of the greater good. Ernie and Ericha claim that if you first Papier-mâché the barrel with newspaper dipped in clay slip, it will help to reduce toxins in the air.. They say that several layers of clay/paper will soak up the toxins and fall off when done, to be placed in the land-fill cans for disposal. I'm not sure I feel better contaminating the ground with the stuff over the air.. As they say, pick-yer-poison. |

I do it the same way as Donkey, with the same reaction. If a giant toxic bonfire is not in the cards where you live, I've done some stealth paint removal with a weed burning/roofing torch as well. Wear a respirator.

Thanks a lot guys.
Donkey. 230mm angle grinder with 24 grit wheel barely touches it before it wears the wheel into round beads. And i can't burn the lower part now. I'll give the guy a call. Guys, do you think i should burn the barrel which will be cast in concrete for the half barrel system mass? I would think that the paint and fumes would just stay in the airproof concrete?

I use a 4.5" angle grinder with a "twist knot" wire brush attachment - makes light work of removing the paint. It does scratch the surface slightly but this can be reduced with a polishing attachment similar material to a scouring pad for saucepans. Wear full eye protection and keep other people well clear as the wires can fly off. www.faithfulltools.com/p/FAIWBT100 |

Morticcio, thanks a lot for that, but i have the exact same tool in 130mm, on the angle grinder, and it doesn't even scratch the paint ;D I've asked Jeremie how much he would take for sandblasting it. And said 70 euros. Well, i gonna show him exactly what it is and pay cash. I think i can get him to go down to 30 or 40. Then i'll bite the bullet.

Max, the paint on your drums must be better quality that on mine! Yeah, me too. You said something about polyurethane? I've never seen a barrel with paint on it of that quality.  |

Guys, it's not a barrel, but a water boiler originaly. And the paint is an oven cured one. Most certainly along powdered epoxies.
