Welding Can Be Common and Welding Can Be Art
Welding may be common, but the welder doesn't have to be. How you approach your work makes all the difference. You can be that guy watching the clock, putting in the time and collecting a check, or you can set a higher standard.

Allen Millyard’s Incredible SS100 V-Twin
After starting on an article about the 5000cc Flying Millyard, which I will get back to, I came across a couple of videos of Allen Millyard's Honda based SS100 V-Twin and couldn't stop grinning.
