I need to drill the 1" holes through the sides of the fuselage for the fuel line rubber grommet (RV-9A, DWG 28, shown in F-970 side view). Sure seems like a big hole!
This hole goes through the side skin and some underlying structure. I've got it to 3/4" with my unibit, but I checked the aircraft tool aisle at Lowes, Home Depot, and Menards with no luck for a bigger unibit / step drill.
They did have one that went through 1".... it was custom made for electrical conduit and had lots of intermediate, unlabelled step sizes.
What have others done?
Thanks,
