Hello, all. I decided to branch out and try my hand at making a cheap cold smoke generator.. Using a soup can, soldering iron, flex hose, and a box. Oh, and Apple pellets for fuel.. Everything works... sorta.. "smokegen" is about 2ft from the smoke box. smoke went from TBS to almost a brownish (creosote) and heat was nuts high.. Smoke box was vented, but it got way hotter than it should. Once I opened the smoke box, I got a little flame out of the flex tube on the smoke box end.. So yeah, it was hot LOL Do I not have enough draft in the soup can, which causes the unclean burn and smolder, as well as excess heat in the smoke box? Thanks, all!
