That is why I have a bunch of these now. https://www.youtube.com/watch?v=gX7zVyN-pl4
Saved my bacon when I had to drill and tap the small holes in the cast iron base column of my mill to mount the limit switch rail for the power feed I put on the knee. The casting is not exactly flat nor round where I had to attach the brackets. Trying to hold a hand drill perfectly perpendicular in two different axis is not a gene that I possess. I can come close with one or the other but never both.
Where did you file on the side of your saddle? Everything looks factory ground.
+1 on the drill guides. Has to drill and tap over a 100 3/8 holes on some angle iron. No way it was not going to fit in the drill press. Got it all done without breaking a bit or a tap.
