nice that's the kind of stuff I like to see people building their own gear. I thought about adding a blower just for the purpose of burning the coals up after a whole night. What kind of blower do you use. And how do you control the speed?
I went to a local auto parts store ( Autozone ) and purchased a blower motor and squirrel cage fan ( Honda Civic ) for a car I own. Made a housing with 16 Ga. steel. It's 12 volt, so I used a regulated power supply I had ....... and I'm using a PWM to control the speed. The air inlet pipe is all 3 inch Stainless.
