Very nice work, I did mine with my small Miller XP130 mig, I also have a much more industrial Millermatic 200, on the hitch in my post above it has a little tig welding on the square tube as well. The aluminum float bowl I did that weld with my Hobart HF 250 TR, an older design it weld...
Really neat!! It was always a treat when I used to go overseas to look in the shops, most were more than glad to let you look around when they knew you were from another country.
Thank you for your posting Magnusk750.
The float bowl on the right if you held it up to a light looked like a "star map", on the left one I fabricated because I could not find a piece of round bar large enough to machine a billet one.
