In this project, Tim wants to convert a copper bowl into a bathroom sink. The problem is there is no drain hole in the bowl. To get a perfectly round hole in a piece of metal, you will use a hole punch or knockout punch. Using a series of smaller to larger hole punches is the best way to make a large diameter hole.

First, drill a pilot hole at the center of the desired location. The pilot hole should be just larger than the bolt on your hole punch. Insert the bolt with the one side of the knockout punch through the hole and thread on the cutter side of the hole punch onto the bolt.

Use a wrench on the drawbolt to pull the cutter through the metal. Continue tightening until the cutter breaks through the metal. You can then, just lift the cutter through the hole.

The first hole should be larger then the bolt size on the next knockout punch. Repeat the process with the larger cutter. This will allow you to make the hole in the bottom of the bowl match the size required for your sink drain.

A regular bubble level, torpedo level or a electronic level works well for small projects, but they have limitations due to their length. Every time you have to move the level, there is a chance for error.

The new laser levels can project a line from ten to thirty feet. Most of the laser levels have an adjustable base so you can level it. Once it is level and at the right height, it projects a line onto the wall. A laser level can also project a line around a corner. There is also a wall mounting base. Camera tripods work fine for holding the laser.

This tool is not only fun, but user friendly as well. The laser can be harmful to your eyes so use the tool properly.
