How to Pre-Drill Angle Iron for Grind Ledges by Ramp Plans Online 2011

http://www.rampplansonline.com A quick video showing how to pre-drill countersink holes for attaching angle iron as a grind ledge. This is a short tutorial, with visual information only. A more in depth video is in the works. What you are seeing is 1) tapping a target hole with a screw and hammer 2) drilling a hole using a 1/8" metal drill bit 3) using a #10 countersink bit to bore out a space for the screw head to fit flush with the ledge. It's really simple, if you do it once you'll know how to do it forever! Happy riding. More plans and info at: http://www.rampplansonline.com
