I own a cheap but relatively effective solid metal bowl-shaped fire pit:
(football [soccer ball] provided for scale)
We sometimes have difficulty getting it lit - the smallest kindling takes well, but I think it doesn't burn hot (or long) enough for larger twigs to catch. I've been wondering if maybe a bit more airflow would help.
Would you recommend drilling some airholes in the base of the pit? If so, any tips on size and/or location? Anything else I need to be careful of - such as integrity of the weatherproof paint?
