2 tons I think its a  fair guess, fire bricks seam heavier ,  3 kilos each?  some in the top bell plus the core , the sand was say 10 buckets, and the old terracotta tiles count I think, is it a good number? It stays warm 36 +  hours this time of year, but one fire a day I prefer now

please help me calculate the mass of my stove , single skin yet, it has aprox. 400 bricks at about 2,7 kilos each , the core has thin mortar but in the bell's walls there is a lot of clay & sand , add also the number of the fire brick in the core , which I did not weigh

'I’m thinking of a circulating system that would solve the problem of it being colder further from the stove'
I had the same problem , my room was way colder than where the stove is , my solution was a 200 mm pipe with a fan blowing air from the top of the bell where there are 26-30 degrees C  2 meters through a hallway into my room , which is now heated furnace style, the air returning through a grill low in the rooms door

I got  a cheapish 100 euros  welding machine , entry level, it has both rod and wire ( mma and mig ) ; next week I'll try welding the frame , with the 1mm wire what value of amps should I set?

I have an experiment going in my shorty, I  used some old petroleum coals with spruce on top , they are for other types of stoves , they do not burn the right way but they still give off heat, after the spruce burned I left the inlet mid way , and hours later the egg coals are alive

biggest load yet, little to no steam

one fire a day for now at between 2 and 10 degrees C, this load's heat I think will last 36 hours, welder coming in a couple of weeks

before I moved here 3+ years ago there where real winters, with heavy snow , ice on the lakes up to a foot thick , mostly below freezing 4 month , with lowest of -25 C, so it is possible , but I doubt it , last years the winters got mild little snow , 0 deg C to +5 , only small freezing gusts .
I am very glad with this core you designed , thanks a lot

is there the roar you know? https://www.youtube.com/shorts/KF6lO16Ve1I
the smoke /steam is low https://www.youtube.com/shorts/64-sAlZ1mkw , gas temperature in the open damper around 50 C, the bell heats fine, the terracotta wall reached about 40 C(i did not install outside control yet, left the bypass fixed a thin crack open)

LE: the end of the burn temperatures , it was already warm from the days before https://www.youtube.com/shorts/H6zZ81-n59E , I think it requires the second  skin, splits are prepared

you mean that ? https://www.amazon.in/Digital-type-thermometer-degree-Celsius/dp/B07DZLH1VH
I already have  one, I can shove it right now in the old unused flue damper , I do not close it anymore , you said closing the intake in the airframe it's better, a brick does it for now

LE: 40.2 C , the intake is closed hours ago, in full fire will be of interest what it will show

there where 2 degrees C  , It was transparent to white , I just think it is steam as I increased the fuel and the bell finishes drying , tomorrow will be 2 thirds full. I will record in silence to listen if the roar is good. Please tell me if a k probe inserted at the chimney's vertical start is good, or where else to measure , there is no pipe exposed, all flue is in-wall bricks
