My question is this: should I add more intake holes or is what I have enough? I thought about building this kind of intake cover, so more holes isn't a big deal:
Assuming your drum is otherwise reasonably airtight, you probably won't be able to get the temperature above 250 degrees with four 1/2" holes. Initial heating up to cooking temperatures will also be more difficult.
