Hey there all, My name is Lou and I reside in the Chicago land suburbs. Fairly new to the forum, have posted on a few threads here and there, but have not formaly introduced, so here i go! Forum name is Trackmaster, after a company i welded for back in the late 70's - early 80's. Thats where i cut my teeth so to speak, welding thin wall 4130 tubing. We had the entire Redline account and made all of their BMX products, as well as Robinson and another or so. We also made and jigged, welded, Trackmaster Harley flat track racing frames. Auto 4130 racing chassis ( probably have thousands of hours on 4130, yeesh! ) From there went on to Aircraft engine mounts, airframes, etc. for another outfit. Was cert'd to mil spec's for some proto work for the F-15 eagle fire control systems produced by Hughes Aircraft Corp., ( worked for a Job shop, where we did a lot of sub'd out work for larger firms and had in house cert's ) Microwave guides, Actually worked on a reflector that went up in a satellite, ..... wonder if that sucker still orbiting, or if it has saddly burned up! lol! Some structural stuff for big arena class concert lighting boom sytems, fleetwood mac or someone, can't remember. Anyway, currently an Airline Pilot, but have a side fabrication shop i maintain, cause ive always had a love affair with welding Tig, in particular! Just recently got a 250EX, couldn't resist the features vs. price point. Fantastic arc, and capable of amazing welds, but unfortunatly, having some issues with quality control, and to be fair on the first machine, likely shipping drop? I'll post fully under the tig column. - peace, Lou
