I don't know why I didn't go with brass, guess because I had alum on hand and some steel. But still need to get a couple more pieces of steel. The aluminum is tricky to bend, as I couldn't find any bend able stuff so 6061 rod. Have to heat it and then it's may still stress crack on some of the 90s. So that's why I'm also doing steel. A lot more forgiving in the bending and welding. Was having a hard time keeping parts in place even just to get a tack on them. A little bump or poke with the rod and they are moving. So I made this up to get square 90s and to hold things in place. As long as it last for a couple it will be fine. Just have to get a quick tack
