I suppose. I looked at those but noticed apparently they are sold with
only one cone (outer bearing race).

That might depend on your definition of "cheap". Can you post a link to
any such sales of cones for 24 TPI axles by bike shops that have an online
presence?
I haven't even found a place on the Internet to buy the cones for 24 TPI
axles.
And I wonder if a 24 TPI axle will work with the most common bicycle hubs
meant for 3/8 inch 26 TPI threaded rods and cones.
I would switch if that's what's necessary, but at first look it appears to
be difficult. But of course that might just be inexperience talking.

I'm talking about the most common axle for geared consumer grade bikes,
that's what's listed as (3/8" 26t). It appears to be much closer to 27 TPI
than it is to 24 TPI.
I suppose the most common axle threading might not really be 26 TPI, it
might easily be metric, but everybody calls it 26 TPI. The axles I have
appear to be less than .371 inch diameter which isn't exactly 3/8 inch.
That might be because of the threading process, or it might be because
they are metric and aren't really 3/8 inch diameter.
It does seem strange that European or Chinese bicycle makers would change
a 24 TPI specification to something non-metric like 26 TPI. So maybe it's
not really 26 TPI.
In any case... It's a bit strange and disappointing that the most common
axle "26 TPI" threaded rod is not sold in the United States. But oh well.
I ordered a couple of replacement axle assemblies for the standard 3/8
inch 26 TPI axles that appear on most geared consumer bikes, just to get
the axles.
That's my workaround. If it satisfies, maybe I'll know more of the lingo
by the next time I need help with it.
