Jeff; About the welding, when I was younger and went into the service I was sent to a school, Metal processing specialist, now what in the hell is that. After awhile I found out that it involved all types of welding (now mind you this was all for beginners), and testing of the metal for cracks inside and outside, anything to do with metal.
So now I am a welder, now remember this all about 50 years ago. I got to the point that I just loved tig welding all the different types of metal and if I don't say so myself, I was damn good at it. All it take is the practice. I got to the point that I was an Air Force certified air craft welder.
Look at what you built for yourself, and it looks good. If nothing else you got the self satisfaction out of it. A job well done.
