I shortened a trailer axle today. Cut about 24-25 inches out in the
middle. Then I clamped it up. Deliberately put a very slight arch in
the setup with a shim in the middle. With it clamped up in two
directions to straight pieces of heavy bar I tacked welded the 4 corners
of the tube.
Then I unclamped everything and welded the top, then the bottom. I
figured worse case that might take out some of my shimmed arch. Then I
welded the front then the back. I ground down a flat spot in the weld
on the front and back and checked it with a straight edge. It dragged
full length on both the front and back. I suppose I'll have to spin
the tires up against the old spiked board and measure the marks to see
if there is any toe so I know which side to face forward.
FYI: I know from experience a trailer axle toed out will destroy tires.
Flip it around, and its just fine if its not to much.
