Wrong side to drill

If you look carefully where the arrows point in this picture you can see a dent very close to where you would be drilling the hole. Don't drill this side. The bit will wander, possibly even if you have used a center punch. If the bit wanders it will at best drill in the wrong place, and at worst will break the drill bit and possibly hurt you when it goes flying.

The next page has a picture of the correct side to drill.
