Axles are critical and very inexpensive. Buy a Dexter or some such,
made to your spec, and be happy forever.

My local trailer building supply house has "high speed stub axle
assemblies" with a stub 4"long and 1/3/4"in diameter made so you can
build your own axles. I assume they are designed to go into some type
of pipe or tubing and welded in place but what kind. The u bolt spring
hangers they sell are for 2 3/8"dia . This leads me to believe maybe
2"schedule 80 pipe which is 2 3/8"OD but 1.90"ID. Is 0.015" play too
much, should they be wrapped with shimstock? There is 2 3/8"tubing
available but the ID is 1.749" so they won't fit that. The seller
(princess auto) has no idea either. Thanks

They are for welding onto square tube to make a rocking axle dual
wheel mount, or for a solid set-up, welded to the trailer frame members.
They get used on a lot of farm equipment, too.

Just buy the built axle if you are looking at a standard single wheel
axle design. You can't build a decent safe axle for what they want for
one, unless you have an exceptional scrap pile and the know-how to do it
safely (which, if you are asking....)

Can you jig up the stub axles to keep them in line? Reliably? And weld
them in place accurately?

Just askin'. Better to realistically assess the chances now, than to
spend a bunch of money, then have to do it all again for the next try.
