I did a few pieces in the oven with oil a while back and they came out with an uneven finish.
after cleaning they were just gray but haven't rusted.

I didn't make this, my friend Joe has the same mill as me but he converted his to CNC. One of his first projects was to make a spindle lock wrench for the mill to replace the piddley little soft one that comes with the mill that everyone breaks cause it is a loose fit and too soft. The mill he converted is the popular to G0759. The wrench is aluminum with a steel pin insert and a set screw to lock the pin in position. What a great upgrade, thanks Joe!
I don't know if this is a good thread? Makes me want to convert my mill and I didn't need any more reason to do it before you guys started posting pics of the stuff you have made!
Kevin, I need to think for a bit to figure out exactly how the heck you made that beehive ball thingy. You better be careful with that computer in the shop. I can hear you now, "Hal, ...Open the collet Hal. Hal, open the collet please..."
Look at the black oxide kits from Caswell. Not quite as good as the hot bluing process but they do a pretty good job and much less expensive to setup. Less hazardous too.

Jim, I do talk to my computer sometimes when it doesn't do what I want
The part is 3.0" in diameter and it is 2.5" across the flats so I was able to make all the cuts in the vise. I used an .063 wide slitting saw to cut the grooves around the sphere, I didn't take any pictures of that operation
This is the first operation
2nd operation
3rd operation was to index part against the stop and machine the tapered step cuts
