  1. Draw your measurements on the aluminum using either a fine-tip marker or a pointed scribe. An awl will also mark the aluminum well.

  2. Cut your aluminum manually with a pair of sharp metal scissors called snips, which are available at hardware stores.

  3. Cut your aluminum using a high speed milling cutter. This router cutter goes up to 45,000 RPM.
