Answer - I don't know?
Here is a good example that brings money in the door.
These are swing arms ( rear end ) for Harley Davidson Softails. Some times its like a factory around here. I don't post a lot of that stuff on my blog cause I feel like a sweat shop doing production stuff and I wouldn't want to bore anyone.
Behind the swingarms is a red case filled with crazy expensive inverter Tig welder that I use for doing repairs at restraunts around LA. The best part of this job fixing kitchens is I can trade welding for food. Then I take Brie out and look like a high roller, ha ha.
I have fun doing all the jobs.
