just drilled a whole in the triple tap, kinda hard inconel has a lot of nickel in it. I used 2 1/16 tiNic drill bits from homedepot. then spaced with the washers that come with the brake and then followed the drill through the existing hole that I made, careful not to go through the barrel. I cut off a piece of the drill and tapped it through the hole and then welded it! cleaned it up and painted it with teflon moly paint to give it that clean look.
