== PREAMBLE == Have you ever made a panel or a bracket for your hot rod, only to find out that it was flimsy and flapped in the wind? Here is a way to firm up those flimsy panels and brackets so that they hold solid and release the air that flows over them. [['''How to make 'em''']] Start off by drilling a hole or series of holes in the panel or bracket that you want to make using a drill bit that fits the pilot hole of the dimpling die. [[File:1_sheet_metal.jpg]] After the hole is drilled, insert the pilot bolt along with the male and female dies. Center out the die in the hole. [[File:2_centered.jpg]] Using a breaker bar, start tightening down on the pilot bolt until it comes in contact with the panel (sheet metal). Spray some WD40 on the dies and threads of the bolt to ease the strain it causes on the metal. [[File:3_tighten_down.jpg]] After tightening down to an appropriate level, this is how it should turn out. [[File:4_bottomed_out.jpg]] Nice line of holes. [[File:5_end_result.jpg]] If you were making a bracket that required stiffing to make it ridged, this is what you would end up with after making a series of holes and using the dimpling dies. A ridged panel that would flow air through it, hold air back. [[File:Pickup_panel.jpg]]
