I have 10 sets of Boston steel spur gears ( 1" & 1 1/2" Dia.) that I
need case hardened. Can anyone direct me to a reliable, affordable
case hardeneing site? Thanks.

there is a product called Caseanite. It comes in about 1 pound cans.
You heat your parts up to cherrie red then coat them with the Caseanite, then heat them again to red hot the throw them in a bucket of cold water.
Shazzam........ there case hardened!
just dump the powder in a old loaf pan and roll the hot parts around in it to coat.
