great tip!
i usually use the smallest bit in the arsenal to pilot drill all of the holes, this also helps with keeping the holes where you want them.(small bit wont "wander")
then step up a few drill sizes drill them again then drill to you final size.
just remember a .030 bit will cut a .032 hole. thats just the nature of drill bits they all make a bigger than they are hole. (hope that last part made sense. )
or abe, you could send it here and i would/could do it, to help out.
