I need some Help with trying to build a Rotisserie Smoker. I would like the Shelves/Racks to be 72" Long x 30" Deep with 5-6 Shelves/Racks. How would I determine the diameter of the Gear/Sprocket I would need to handle these Shelves/Racks. I plan on Smoking/Cooking 4-6 250lb Whole Hog Running Style. Thanks for any Help.
 
To start with you needed to know what your motor rpm (1725 ? ) and your final rpm of the spit. I used a 40/1 reduction gear box with a 1725 rpm motor and small gear the out put shaft of the motor to large gear on the gear box input. small gear on the output to large gear on the spit.
If you count the teeth on the gears 10 teeth and go to a 40 tooth gear you should have a 4/1 reduction for example. I think my final was about 1.75 rpm. that hog cooker was put on the hill along time ago so I don't remember the exact sizes I used.
You are going to have one heck of a cooker when you get done and that's going to be a lot of good pork.
This is what i did on mine so good luck and I will be following your build.

Thanks for the info. For the shelves to be 72" L x 30" D how Deep and High do you think the Smoking/Cooking area Dimensions would need to be?
 
Well you have to figure out how you will attach the racks on both ends and how much room that takes 4-6" so your length is about 8' probably 7'-8'wide you will have to lay out your spit try some cardboard to make sure it will turn inside your pit demsion.
Just a few question how often do you plan on smoking 4-6 hogs?
Each 250# live hog should yield a 175# Caracas and will feed roughly 150-200 people per hog that A big crew and takes a lot to cut up.
The most I ever cooked was 3hogs at one time and after that i did not want to do another for a while.

I will do one now if some one want a show other wise I prefer butts less work and less waste just my thoughts. you may want to think on a smaller scale and build More rigs
More for you to think about.
