        Thanks. I asked how it broke since it looked new. The guy said he went to his neighbors to mow his yard. Then the neighbor backed his trailer into the mower and broke the part. So it wasn't under engineered like most parts are. Guess you can't design a part to hold a trailer ...Bob

            I built a ramp that was meant to hold a trailer.... A 15000 lbs trailer from Sysco..........

            Because you never know if they're gonna see it or now and I am not building it twice.
            if there's a welder, there's a way

              Great Job! So, this part is mostly made of aluminum?

                Prob so with some other traces of white metal like magnesium and zinc. Who really knows. But its working just fine in the field...Bob

                  Many outdoor products like weed eaters etc., use metal with a high zink content.
                  When you strike an arc on the metal it has a green glow .
                  The welding stores sell a filler metal rod made to weld this high sink content metal.

                    Me and you must not be shopping at the same welding stores. 2% lanthanated tungsten is a unicorn to my LWS, they'd probably have a nuclear meltdown if I asked for something to weld aluminum-ish metal with a high zinc content.

                          True
                          But that filler is for Zinc BASED metal. Not for Zinc ALLOYED metal.
                          BIG difference
                          If that part would have been zinc based it wouldn't have welded successfully with 4943.

                            A while back I welded up a side view mirror internal frame for a BMW. The owner thought it was magnesium, but my vinegar test proved otherwise. I couldn't decipher the casting marks so I let er rip with the tig torch. I think I used 4043, but it might have been 4943. Can't remember if I had it back then. The casting didn't weld terrible, but it sure won't win any prizes. It also didn't weld like I expected it to, so maybe it was a funky zinc alloyed casting. Who knows what those German engineers had in there.
