These photos look like I drilled and taped my holes at an angle. The camera angle makes it look like that. I checked each hole with a square as I was drilling it. All of the screws used were 5 mm screws so I drilled 5 mm holes in 4 places.
I tapped first with a taper tap and then with a bottoming tap
One of my tricks for cleaning out a blind hole hole is to flood it with WD-40 or similar lubricant which flushes out that nasty cast iron powder.
