Amateurs practice till they get it right, professionals practice till they get it wrong, analyze why it was wrong then keep doing it some more. It is a trade that you are always learning in the more you can learn the better off you will be, learn the odd parts of the trade, if you can take some classes in metallurgy, basic machining, and some basic CAD. I applied for the job I am currently at as a CNC operator, they let one of the welders go and I was the only person who had production based welding background at the shop, I am not the greatest welder by any means, but I can run just about any tool in the shop, from manual mills, and lathes to TIG welding stainless on a rotator (running two pedals at once). What I am trying to say is get the welding down, but don't stop there, like stated earlier benders, shears, breaks, plasma cutters, OXY FUEL rigs, (My biggest pet peeve in the shop is people who don't know how to set the blade and feed speed on horizontal band saws, learn it!), Learning fillers is a big thing. Aluminum is good to know, where do you want to take your fabricating career? Do you want to stay in the racing stuff or go into other industries? Another big thing, be drug free and sober, and show up sober EVERYDAY, seems hard for people here in Havasu to grasp the concept of showing up sober to work.
