Yep, I knew better and put in six 3/4" holes. Put plugs in three of them and never take the cap off of one of the remaining intakes. My next drum will have one 1/2" nipple and one 1" ball valve. The current drum runs too hot with one 3/4" nipple open and too cool with the 3/4" ball valve full open. So I figure that a 1/2" nipple and a little ball valve will be perfect. I'll let you all know.
