Just a small item to add for you. I own a metal fab business, we weld aluminum everyday, buy aluminum everyday, and have access to extruded aluminum that you may not be able to get a hold of. That being said, i will not make my own. I have in the past, and I have some stands that are unlike any on the market. I have not had a stand fail yet, but---------you WILL NOT be able to make one lighter and as safe as the ones being made out there. My advice, with a grain of salt, is get one close to what you want and make a couple modificaations. Good Luck though, and Iwant pictures of what I believe will be a $500 stand after you get your welder!
