Been working on the drums!
This thing is getting out of hand. I've got enough drums to cook for an army!
First drum is a DIGITAL air controlled model.
Second model is a MANUAL controlled model.
Digital model can control at +/- ~4 degrees.
Manual model has a +/- 18 degree swing. Not bad for BBQ but I like the tighter control better. It has too much deadband to control a fire.
