Service manager of a home appliance shop.
Small engine/motorcycle mechanic at an area motor sales concern.
Packager at a local chemical compounder. Carper cleaner, windshield washer fluid and sidewalk de-icer were just a few of their many products.
When I finally did get a foot in the doors of businesses where my skills in the electronics tech/electrical engineering and IT fields could be fully utilized, the rest became history.
As soon as I finish equipping an electronics R&D lab, acquiring all Park Tools bicycle-related service equipment offerings, finding a frame jig and sourcing a capable TIG welder I could give a side business or two a go. But probably not until retirement - there's no way either of those will pay anywhere near what my current line of work does. For now I'll tinker with these things because I like doing them, and I enjoy helping others with their projects.
