Step 6Drill screw holes
This gps has a convenient curvature that allows some room for the screw heads.
Use the handlebar mount as a screw hole template and scribe the positions of the screw holes into the metal with the safety pin.
A drill press is ideal. At the very least, clamp the metal firmly before drilling. The scary thing about drilling metal is that sometimes the drill bit can catch in the metal and cause the metal piece to spin around wildly. So you definitely want to clamp it down before drilling.
The awesome clamp shown below is available at Widget Supply (www.widgetsupply.com) for around $15. You can position your work fimly at almost any angle with it. It's one of my favorite tools.
