LOL yeah we cheated and just cut them out when the frames were waterjet cut.Used precision cut washers to fill in the gaps when we hammerformed.holesaws work well too but watch your final size as they can be a bit wild.Especially in the bigger sizes.And yes a "lot" quicker than chain drilling..Hope to get out to the Man cave today..Been a rough one..
