I started reading this, since a friend of mine got some new welding equipment. He's going to help me fabricate a drum to use on my grill. I have 2 questions though:

1) Is there any negative to hand cranking until I can mount a motor? (Other than the possibility of unevenness due to changes in the force I use)

2) On a grill, why exactly would I need the regulation and control that you guys are talking about when I can just adjust the burners on the front of the grill?
