Depends on what you are going to use them for.
Off road use = Who cares go have a blast.
On road= Don't come through California with them. If it should fail and in the investigation it's found out that the rim fail due to being welding upon. Guess what. Illegal and unsafe repair of a safety...

One 1/4" wall thickness tube would work but would be too heavy as far as I'm concerned.
2X2X1/16" would work just fine if you feel you need to go thicker I wouldn't go thicker then 1/8" wall.

Two reasons for this opinion. One the lathe is not strong...

Yep as stated above CFM first. 60 or 80 gallon with a true five to ten horse motor. The bigger the better. Then when you decide you want to expand by adding an aux tank connect them with the largest plumbing possible. 3/8 is way to small to fed a tank.
When I set up a 30HP hydrovane. it was feed...

That's what the NEC allows for. In a residential application and don't quote me as I don't know what the exact values are but your are allowed to have more amps in breakers then your panel is rated for. For that exact reason. You will not be running everything at once.

If you take 6061 T6 and try to bend it in a brake at a tight radius it WILL crack.
T4 is considered soft enough to use in a brake.

Give it a shot and see.

The above tip on the acetylene torch works I've used it for years and works great

yep happened to me in trade school. Drink more coffee and it goes away...

Sell it and buy something that will work. Spindle speed is most likely too high for anything other then aluminum.

sell it and invest in a tool you need.

I think the only real difference is being able to plug a push pull gun in with no controller. other then that same features in a different package

About 400F for preheat and if you desire 1200F post heat and let air cool slow

Yes sir Nr211 or 212 is just about the best non code wire to run. Welds great even in high wind. I'd have to compare the bead quality to a nice fresh from the oven 7018 just a bit smoother beads
