The holds came with a template to lay on the hull. So i taped it where i wanted them and traced the template with the marker then began cutting.
I started cutting with a 4" cut off wheel but switched to the little wheel on the dremel it seemed to work better. The hardest part was cutting those tubes. I must of cut the tube like 100 times to get the hold to fit all the way. I used a chisel and hammer to get the ends of the tubes off (at the back of the Hull)
Final shoot. This is what was left to get the hold to fit. Thats all the way out the the outside of the hull. The Trinitys are DEEP.
