自製木屑爐 / DIY Sawdust Stove 

The metal lid inside was a good idea, instead of sand. Good job. I like it.

Verimsiz bir soba. Daha iyilerini gördüm. Rusları bu konuda takip etmenizi isterim.

The Next one you build. 1) Bring Intake Air, In from outside is better. No warm air from shop leaving through the Stove. 2) Lower your exhaust to just above the middle of the drum, and it will be much better/hotter. Drum will get much hotter on top and Radiate into the shop better. Exhaust Pipe will become much cooler. More Heat in the Shop Now.. Much better. Everything else is good.. Correct Size and Ratios. Longer Exhaust outside, the Better the draft. Always: More Intake Volume Available than Air that Enters the Drum. Hot Air Expands. Ratios Important.

Hola! Por donde entra el aire para la combustión? Saludos

11:00 looks like you are welding a galvanized elbow. That is Zinc or Cadmium plated and extremely toxic to breath the heated fumes from welding.
