Bronce (not brass!) is always a good bearing material. But the stud
running in it has to be hard. Case hardening is a good solution,
because the hard skin doesn't have to be deep at all.

The problem with bronze here is that these bushings get a lot of shock
loads as the wheel rides over the road . I went to the only supplier in the
area that services small accounts and got some 4140 bar stock . As supplied
it's at about 28-32 c hardness , which should work OK in my application .
Gotta find a local source for case hardening stuff for the studs , or order
some from enco or somewhere .

I will be making some bearing cups to replace the ball bearings in
the steering neck with a tapered roller , and need some suggestions
there also . Thanks !

Free machining steel will do the job and help you in machining it.

I think I'll ask my buddy the machinist if he's got any of that hidden in
his supply ...

HTH,
Nick

I've learned a lot from lurking here , thanks so much for your advice !
