First, Thanks for your advices.
1. What type of device could replace the blower ?
2. I used about an inche under and over the piece. I see I was wrong I'll try it as you said.
3. When I did researches on the forge, I was seeing a lot of "furnace" like designs so I designed mine on what I saw. But these top closed designs are mostly used for gas forge isn't it ? A solution would be to remove the door and cut the top half of the keg, then it could be more appropriate.
4. With an air flow like this I assume the charcoal I use will be consumed quickly.
5. At the end of the video I show that I changed a bit the design, then cleaning the inside of the forge will be easy, and for the cleaning of the air duct I made a removable pipe extension so I can access and clean the embers in the air duct.
6. Thanks for the idea, I saw their model I think I will modify my keg to fit into these type of forge model. (Maybe as I describe in the 3.)
Your return really helped me thank you very much !
I may not been clear on my video and I'll change it but this isn't a how to video, I want to make an evolution of my project to make a forge. And with timeline it to be more efficient, with help of the comments I get. I'll specify that in the video description.
Okay you think my editing does not show what really mater, I will be more concise for the next ones. Thanks for your return
Sorry I saw a section coal forge and I posted in there. I thought it was the good place.
And about the propellant I use it just charcoal. Find coal in my country is harder than finding basic charcoal ^^
