How to make Dirt Bike 'Bark Buster' clamps, Drill Press, 1/2 inch Hole, Lee Isenberg TN 2012

I made some bark-buster clamps for my dirt bike out of some scrap aluminum. Its a 1/2' inch hole, then step-drilled to 3/4' or 7/8' to fit the handle bar O.D./diameter. Soundtrack includes ZZ Top Afterburner album, song: "Sleeping Bag". Afterburner has always been 1 of my favorite ZZ albums. And just FYI, ZZ Top should Not be confused with AA Bottom!!! This is actually an american made Rockwell wood drill press that I run as slow a RPM as it will go, it only has 4 speeds. It works for a lot of metalworking projects. My cheap, Chinese drill bit did ok. Drill Press Operation, Lee Isenberg 1/2' inch Hole June 2012
