Yes, you could. Stick with Lincoln or Miller welders and you'll do fine. Add to the list of tools an abrasive cut-off saw, a hand grinder and grinding wheels, a tubing bender, a welding helmet and gloves, etc. And don't forget that trip to the powder coater.
Thanks for advise - I don't know anything about welding machines, even if I tried it ones.
Rest of the tools I have - love tools! Well, not a tubing bender... but I am not buying it anyhow - will figure something out... Now I am excited!
... powder coating... ghm... need to do a research... do I need it if right materials used?
