| Subject: | Drilling Flap Bearing Blocks |
I'm ready to drill the bolt holes through the F445 Bearing Blocks, but
I'm concerned about the possibility of the drill bit walking and the
hole being way off location when it breaks through the other side even
though I used my protractor to set the drill press table normal to the
drill line. I have considered using a 3/16" spur point drill to make a
pilot hole and then opening up with a #10 per instructions. Seems like
that might work better than just punching through with a #10 in one
shot. Am I over analyzing this?

Hi Stan,
If I were you, I would start with something a lot smaller, like a #40 and
then work my way up. Use a center punch to guide the first hole.
Replacement blocks are not very expensive. Ask me why I know this...
