I was putting my drum together and decided to give everyone a math point of view on calcuations.

Stay tuned on another thread for my drum build(x2)

MEASURING FOR 3 INTAKE PORTS

First thing you want to do is take the diameter of the drum. Remember if you measure the inside of the drum you need to add for thickness of the drum walls twice.

I came out to ≈22.75" I rouned most of my measurements so this might have a slight variance to others.

Next you find the circumference of the drum

C=πd

C=(3.14)(22.75)

C=71.435

Now that you have the circumference you will need to divide by three

71.435/3=23.81"

If you mark all the way around the drum 23.81(or just round to 23.75 since the tape measure will have this marking) you will have three almost exactly spaced holes for the intakes. The same calcuations can be used for the racks if you use three screws or divide by 4 if you use 4.

Yea, im a nerd that loves to eat. Anyone needs any help making calcuations harder than basic algerbra let me know.

Ill add later the formula to use so i can have a perfect 8 1/2" holes in the lid.
