Yesterday I welded a chimney damper and a bypass. Damper turns 270° to close....  Here is bypass...   |

Hi, On the door for ashes and primary air of a cookstove , I used the first rectangular system ( in aluminium, the second one, nicer, round, in stainless steel but 10 cm in diameter was too big). Both were tight, even the cheapest one! (on pictures, metal is brass, more expensive...)  ![]()  It is possible that, compared to Klemen's and Peter's system, the air might be not as well injected downward, that is toward the floor channel... Benoit Edit 1 : Thank you Satamax! Edit 2 : The round one is a bad idea here as it would not fit being too big, sorry! HM, I am thinking that those slits provide higher air drag compared to only one opening... |

And Laiton is brass. Otherwise, english speakers might not understand. Wow, Satamax.. I didn't know Laiton is brass... It sound like a brand-name :-) |

Oh well, I just realised that chimney damper could be made only with 90° turn and still be secured in both positions in gravity only.... :-\

Yeah I was about to be pedantic and point out 90 degrees ... instead of 270, but you got there quick!  |

Here is the begining of the build... The wet saw didnt arrive yet. I was fiddling with large angle grinder... Its not that acurate cut, but what can I do...  I use clay slip with fine quartz sand for brick laying. Around the openings and cleaning holes I think I will use oertnet heat resistant mortar... Building with chamotte bricks is much simpler compared to handmade red bricks that are really not that exact in size/thickness ( +/- 5mm easily) This is it for now... |

Progress. Here is the recent progress... I got the wet saw this week so i can finally cut same dimension repeatedly :-)<br>In the following days i will rise the back wall and after that start with firebox and riser...    This work has been done in 8 days, each day 4-5 hours.. I have a feeling that i am a slow builder?!? Well i don't intend to start to build faster just for the sake of it... But i would like to hear about other's speed of building... Also i know that i am much more careful than with my build :-) I guess it is because i build for someone else and i really want it to be good work (to a degree that i am able to achieve :-) Regards, Klemen |

Looks nice! Did you cast the bench slabs?

Looks nice! Did you cast the bench slabs? Yes, with regular portlant cement. I do not expect the temperatures to get too high.. ... And I added glass fibers.. |

Looks good, I see you used clips for the firebox like Tulikivi (in the past, don't know if they still do) and some German builders.

I saw this kind of work recently in and opened tiled stove.. Today i cut 3cm chamotte to trapesoidal form to make octagonal heatriser... Next time i will cut slightly smaller octagon to help me with holding the correct shape... I used Ortner fire mortar, not clay... I am thinking that it would be better to leave one gap unglued from bottom to top... So that it can expand freely... Around this 3cm chamotte octagon i will put 3cm vermiculite board for an added insulation, sturdiness tightness...   Comments welcome! |
