G&J Aircraft's Dimple Die Set: Street Chopper's Toolbox

There are thousands of new tools made by hundreds of tool manufacturers. Some of these tools are extremely specific, some work on a variety of parts, others are straight out of a catalog, and a few are handmade, but all of them can make your life easier. Each month, STREET CHOPPER will feature a new tool that will help builders of all calibers, from garage to professional, get their bikes finished faster and with less hassle.

We just happened to be at his shop, Devious Customs, and saw him building his splash guard. When he pulled out his set of dimple dies that he had picked up at G&L Aircraft and Competition, we decided that it was something we needed to show you all and add to the STREET CHOPPER Toolbox.
