So new trailer axles, my problem is that my trailer has a stretched frame. Typical trailer frame rail spacing is 46 inches or so but mine is 57 inches. so an axle comes up a little short. Now I could buy new custom axles but goodness they are 2x as much money as just winging it!
I bought two new 12k pound axles, first step was to cut the spring perches off carefully and move them outward 2 inches each, weld back on with a nice 7018 DC.
That silver band in the middle is where the axle gets cut in half with a borrowed porta-band saw in order to add another 5.800 long piece of tubing and weld that all up nice and sweet!
Axle is now already cut and waiting for the pipe to arrive via UPS

This one was a corker! 1 1/8 thick cast steel loader frame with a crack

Crack was caused by a fleck of dirt in the casting about 2.5 inches in from the edge. Required a full depth grind out, chase the crack beyond the end, preheat to 375F, weld with 9018 rod until flush and then post heat 400F with a long slow cool down to reduce welding stresses. That was a whole day job instead of replacing a $2500 part.

Looks like it should be a fun project.
Had a guy on the FD who made trailers as a side job and pretty much every trailer he made had cut axels. He had to shorten up the ones he obtained, because he obtained them from a mobile home company after they delivered the horizontal condominiums.

Heh, math shows that this tube joint can support 24000 pounds over the 5' span, but its the middle of the axle, so total axle moment is 12,000 pounds but this area has a 3:1 advantage over the wheel load, so that gives a safety factor of 6:1 I don't have anything heavy enough to make those load numbers.
