Some faulty conclusions here... Wood can definitely move a significant amount. Believe me, I've seen it. You must elongate the the underlugs. I would suggest at least 1/16 for and aft of the original hole. Why wouldn't you trust someone who has devoted their life to this? Makes me want to shake my head...

Sealing the wood doesn't solve the problem either. Trust me...
I've always done the 3 hole thing going back to the late 70s. One in the middle and one on each end. Clean up with needle files. I don't understand why anyone would think this is overkill. It's recommended in Buchele and Shumway's book and Dixon's book.
Using the jeweler's saw method as Jim recommends is the best way to accomplish this. Drilling two separate 1/16 holes adjacent to the original pin hole elongates it considerably more than what Jim recommends is appropriate for slot size. Most likely you're going to end up with a slot 5/16 in. in length rather than 3/16 in. in length. It's just not possible to manually drill another hole right next to an existing hole where the outer edge of the new hole intersects the original hole. It can't be done with a hand-held drill. Unless maybe you've got a drill press. If that's the case, then by all means, go for it.
