go cart building for square tubing?
.09 is thicker I would not try to use the aluminum tube you showed on the web siteIt is .05, and is to thinSteel while heavier is better suited to what you want to do and easier to workAluminum is to soft and weak and much more critical on design factors.
Aluminum foil has a low melting point, so not really advisableSure you may have aluminum cooking pots, but they are loads thicker.
Paranoia is a side effect of smoking weed.foil is ok.
I'm alive and well, but I wouldn't recommend itBut when you need a bowl you'll probably do it again, won't you? I would.
when you heat up aluminum it smokes right! well try to inhale that without anyting else n see how bad you choke ! then decide if you still want to fill your lungs with heavy metal by-products !
