I had one before but sold it to a friend after I used it. He moved to Florida so I can't borrow it anymore. So monday I ordered another one and it showed up today. Got it from www.APSkarting.com anybody want their name carved into Skyyk5's tires? I accept paypal. the second pic show the #12 cutter head with a penny for size comparison. it cuts 3/4" wide grooves. the head and blades they send with it are a #4. thats 1/4" wide. way to small when dealing with offroad tires.
