Chances are that if you get a failure, it will be by buckling of the tubing
at the load point. The load fluctuates widely, depending on how heavily the
trailer is loaded, and how big the bumps in the road are. Since there is so
much at stake, I would look for a way to stiffen that area, by welding on a
truss, or some triangular side plates. If you can keep the tubing from
bulging, you will make it a lot stiffer.

The 6k lbs axle that I am going to be installing on my trailer, also
comes with an axle mounting "hanger kit" that is supposed to be welded
on to the frame.

Example (not the actual item) can be seen here.

Logically speaking, it should be welded to the bottom of 2x4x1/8"
steel tubing underneath the bed. That's the tubing that I would weld
underneath the bed.

I have no doubts that I could create a string enough weld to hold
these brackets. What I do have doubts is whether 1/8" tubing would be
overstressed in these attachment points.

My question is, what is the normal procedure for attaching these
hangers, is the strength of 1/8" tubing enough to support that single
stress point, or do I need to also weld some channel, pad etc between
the hanger brackets and 2x4 tubing.

Thanks

Igor,

First, I've never built a trailer.

However, there is some kind of a formula people follow for axle
placement. A small difference in location can make a big difference in
the handling of the trailer.

Or so I'm towed... <a clever pun, yes?> <or by nature, are puns
unclever?

Anyway, if you haven't already looked into it, please do so before you
weld the dickens out of it.

wells.

yes but the wheel wells may not be in the spot for the axle to
balance the load with about 10% of the load on the toung. too much
on the truck does not matter a great deal if not extreeme. put the
weight on the back, bigg trouble

Leo, thanks. What you say makes perfect sense and I will try to do
something to address that./

A separate angle or channel to carry the spring hangers is frequently
bolted to the frame. It takes the load so it should be heavy duty. This
is where a good investment of $30 in a set of trailer plans for something
similar to your trailer would help; it will have structural details worked
out.

Where might one buy "$30 in a set of trailer plans" ??
