If the lathe didn't cause them to crack between the drillings (and this is why most machine shops will refuse the work), they would most likely crack shortly thereafter.
Unfortunately, if you wanna look cool, you got to pay the price...

I may be mistaken.. but I've always heard that cross-drilling was all about weight. Is that not a factor in the decision for cross drilling?
Sorry about the thread-jack.. but I thought this a good a place as any to ask.
