Remember -- the balls are pretty small, so if the race is not
hardened, the balls will be pushed into it.

Well, it was the side of the caster, going down toward the wheel that seemed
to have been hardened.

But, your explanation may be correct, as they proly harden the whole thing,
or at least enough of the surrounding area where I was trying to cut.

One expensive week fer saw blades -- and end mills. sheesh....

Keep an old file around to test things before you try a sawblade
or an endmill on it.

Hmm ... there are carbide grit hacksaw blades -- you could
probably use one of those to cut most of the way down to the axle, and
then split it with a chisel (while it and the chisel are wrapped in
cloth to keep chips out of your eyes, and the balls out from under the
bench.

Good Luck,
DoN.
