I drilled my heavy 18" ride recently for 3 rivets and am very happy.I used the dental floss method to find the sweet spot for rivet location first, and to decide if I loved the sound.Then out came the hand drill. A little clean up with some emery cloth to knock off/down any ridges and in went the rivets.I love it.[IMG]http://farm7.staticflickr.com/6103/6218251003_d93052a2b1_z.jpg[/IMG]
Your rivets look like copper. Is that correct? If so, where did you get them?
