Don’t know anything about the Hells Angels but I have had a few dealing’s with the Vagos when I had a welding shop out in Victorville Calif in the late 70’s. I was the only one in the area that had a Heli-Arc and did allot of repairs and fabrication on their bikes and other equipment. The were a rough looking bunch but never gave me any problems and always paid in cash.
If you worked with them instead of the Vagos, you could have been an Arc Angel...
