I got the upper door open because i was doing some tests, the system was doing a lot of smoke do to insufficient air intake. The door was blocking part of the lateral air intake. Today i set some modifications to the door and the results were very good.
Thank you for your help.

Hello,
After a few months of using DSR2 i have some issues. The design is perfect, thanks Peter! But the implementation is far from perfect.
I don't recomend to anybody casting the core, my experiencie is a disaster. I made the pieces as good as i know, bibrating, puting as low water as i can, letting the pieces to dry slowly for a month. But alfter a few months is falling apart like mud..
I know the iron is damm in these designs where the temperature achive is over 1200º C. But someone have try to make some parts of iron, the ones with lower temperature (firebox?, oven?), not in the riser stub where i think the maximum temeperature is achive.
I have to rebuild all the core, i am thinking of making the riser stub with isolate bricks 1400ºC, and the others parts with fire bricks? iron?
Any advise?
Also i didn't recomend to make a sidewinder inside a bell if you have to rebuid, more than likely, is more complicated.
How you resolve the bell dilatation issue? When the bell is cold the cracks are small but when temeperature rises the crack becomes larger.

When the bell is cold the cracks are small but when temeperature rises the crack becomes larger. Use the firebricks for the box and insulating fire bricks for the upper chamber. Be sure and use a refractory mortar between the bricks and keep your joints as small as possible. With the inner skin or in your case single skin you want very small mortar joints for your exterior brick. That's probably why you are seeing cracks in the face. The mortar and bricks expand at different rates. The way to lay them is with enough mortar to fill the gap and tap them with a rubber mallet till they are touching. Something in the 1 to 2mm range. Good luck with your repair |

The crack on the bell is vertical, breaking bricks and mortar. I think its something that usually happens with the dilations inside the bell. Am i the only one with this issue?
I was thinking of making some kind of joint, like the roads on the bridges, could solve this issue. Does anyone tryed?

What is the stove built on top of? |

The floor is good, isn't a issue of foundation. The crack is above stove, increases when heated and decreases when cooled.

The other possible cause for that crack is not giving your steel door frame some expansion room. It is best to wrap the frame in ceramic fiber paper to act as gasket and to give the steel some room to expand |
