My Uncle Pete is retired in central Wisconsin and is an amateur blacksmith. He has a friend with a machine shop and they've decided that they would like to experiment with color case hardening. My uncle
asked me to find as much information as I could from books and the internet and send it to him. If anyone has electronic copies of Oscar Gaddy's articles, I'd greatly appreciate them as well as useful links.

Thanks, for all the contributions, I like that thread on the Marlin Collectors forum, especially the pictures of the fixtures they made to hold parts during the hardening process. But there is so much back and forth, and the thread was never a how to do it. I've found this, which sounds like it gives a good start

Very tricky--no air contact between the sealed crucible and the bubbling water bath was one thing I learned. But the low wall receiver I thought was too dark from air contact 20 years ago is now mellowing so some colors are showing up-still not great, but passable. Didn't have the guts to redo the heat/quench sequence twice on my Win SS. Breech block very tight now.
