Tapping bolt holes
I'll see if I can locate the tap tonight..however, due to the position and angle of the holes, using the normal tap handle was useless..I put it in the chuck of my bosch 18v cordless and it made it real easy..several easy in and out partial passes (didn't want to twist off the tap in the hole) and it was ready. Even trying to drill out just the bolt shaft is virtually impossible so you will wind up tapping a combination of threads and nutsert. The length of the drill allowed for accurate alignment as well as being able to put some pressure on the tap to help drive it. Still was glad I only had to do just 2 and not 4
