I know little to nothing about different kinds of metal materials. What kind of steel did you use for the various parts?
Just about any structural steel is fine. ASTM A513 hot rolled steel is what I used for the square tube. Check metalsdepot.com. The round tube for the handle was 1020 but not critical.

Thanks! What wall thickness did you use on the square tubing?
The tubing thickness is in the bill of materials. If you haven’t seen it the youtube video, the description includes a link to the files for the drawings and other info.
