Not Ranked
I did a number of holes in my Lonestar after painting, and pretty much the way you described "do my measurements, use masking tape, drill a pilot hole to start and slowly make it bigger to fit the size of the hole I need." Not that difficult, but as always, MEASURE 18 TIMES, DRILL ONCE!!
I didn't counter sink under ANY of my drilled holes, and would be wary of that. The fiberglass is not THAT thick, and I would be really nervous about judging the depth of the countersink!!!!!
If the nipple is short though, I guess you have no other options. Can you find nipples with longer threads perhaps?
