No problem, Trebor. Glad we caught that before anyone started drilling!
It seems that four 1/16" holes per side will allow for wider, more even spacing across the back of the nozzle. Might be a good thing.
It's been a while since I've taken physics, but I think there's significantly more drag through those four small holes than through the single larger one. Anyone knowledgeable in fluid dynamics? Even so, I think the four smaller holes will offer a benefit.
I'm sure figuring out all the calculations is a rudimentary exercise for a physicist. When I get the chance I'll try four 1/16" holes per side. I'm sure the added drag will call for another aperture of indeterminate size to equal the airflow going through the bigger hole.
