Fantastic!
Congratulations on such a successful retro fit.
This really came out very nice, I can see you have a future in building wood stoves my friend.
That secondary burn was impressive!
As well your welds are getting much better, you do such nice clean work.
The door..........where you open it and you tacked welds on the inside, on the main body you could weld in some flat bar steel and frame it in so you can put in a door gasket.
That would give you greater control over your air supply.
You inspire me my friend.
Well done!
