I didn't have much trouble drilling holes in my first dual deploy altimeter bay. It was fiberglass. But now, I am trying to drill holes in a Loc Precision 4-inch rocket altimeter bay. The altimeter bay has a very thick, heavy-duty "stiffy" inside. Then outside that is somewhat thinner "coupler." Then outside that is a body tube, in this instance a 1-inch "switch band." So I need to drill through 3 layers of paper type materials -- and make an elegant, precisely shaped hole. How does one best do that? Thanks in advance for your wisdom and thoughts.
