Split personality, I fake being smart
What size holes did you drill?
I'm pretty sure 1-1/2" is maximum safe size
Looks like you polished inside the holes to prevent cracks forming?
I use a small 120 grit flap wheel in die grinder with some brown polishing compo
BTW, I originally found ventmasters, RGRH posted in his build
