Threads in frame for grip screws

Received the BSF 3/16"-32 bottoming tap in the mailbox today from e-taps. After work, I chased out the offending grip screw hole. All went well, did not need to feed it thru the frame from the good hole's side, nor fuss around setting it up for the drill press. Feeling for the right "start", it became evident that I could run it gently through by hand and have the tap remain perpendicular all the way.
BTW, I did try the thru the frame method, tempted by how much of the tap's shank was relieved to clearance diameter. Lucky again, there was just enough room between the walls of the mag well to allow the tap to be applied in the manner I suggested above!
