15 gallon mini UDS build question
Hoping some of you who have built a 15 gallon mini can help me out with a couple of questions. I've searched and searched here, but haven't found answers pertaining to a 15 gallon drum.
What size holes should I drill for the air intake? From what I've been reading here, sounds like for a 55 gallon UDS, most folks drill either 3/4" or 1" holes. Since my drum is only a 15 gallon (27" high), should I go smaller than that (1/2")? Will it even make that much of a difference?
Next question... how far up from the bottom of the drum should the holes be?
Any help is appreciated.
