Ok, I'll go against the grain and say that while I usually use my prop reamer, I can't always find it in my messy shop. If I can't I use my drill press.

You MUST have a clamp on the table - not to clamp the prop, but to give the prop something to hit that will keep it from spinning out of your grip just in case. I've never had it happen, but better safe than sorry.

Contrary to popular belief, a drill WILL follow a hole, but there's a little technique involved. You need to hold the prop loosely, so it can "Float" under the drill bit and center itself. This is why you really need a clamp or soomething to keep it from spinning out of your grip.

Bring the drill down into the exisiting hole, and it will move the prop into the proper position, then you can firm up your grip a little and bring the drill all the way through.

Ok, flame suit on. Let's hear all of the nay-sayers.
