Don't forget to make sure you calipers are set to zero, plus it wouldn't hurt to check them on a gauge block. You'll pick up tricks as you advance, I'll give you a clue, you can use software to check your drawing against the actual part.
lol don't have that software.
its not the hole size its the placement.
ill keep working.

thankyou,
