That says it all.
I find myself with a slide that a buddy gave me a while back. I went to work on it and guess what ....? No disconnect scallop under there, and I'm fresh out of 1911 specific milling tools. A search on Brownells brought me nothing. Anyone know how to create the little scallop on the bottom of a slide without a cnc and without ruining it? Dremmel? drilled? Stumped.

McMaster, woodruff cutters.
I don't have a slide in front of me to measure, so grab your calipers and measure a finished slide to pick the right cutter. The geometry isn't super critical, as long as the depth and front to rear location are good, and the radius isn't so small that the disconnector has to climb a steeper face, which could wear it out prematurely. |

Great!! thank you! Now if I could determine which one... |

Straight tooth, HSS, should be plenty adequate for what you are doing. Width should be easy enough, if they don't have one the right width, get the next size down and make more than one pass. Just note that woodruff cutters only cut on the sides, not the faces, so you'd have to feed straight in, back up, index up, and feed straight in again. |

Do you have the Kuhnhausen Volume 2 book? If so, look at page 93 for specs. Unfortunately the radius is not listed, but judging by a 7/8" keyway cutter I have, I think that will be the right radius for you. It's .375" long, .162" wide, and about .050" -060" deep at the center. Let us know how it turns out.

I have manuals mixed with reloading and popular mechanics.. |

With those dimensions, you're looking at a ~3/4" diameter cutter ETA: HERE is the cutter you need, ~$25 |

There is another way to make a cut that will work. Infinity uses what looks like a 1/8" endmill at opposing angles to cut a V shaped recess instead of the semicircular recess.
Not my photo but it shows the essence. 
If anyone's interested I can do some measurements. |

Ken, do they do anything atypical to the head of the disconnector, or is it a standard configuration? It seems (just from looking) that the 'v' cut might make for a slightly rougher ride for the disco as the slide cycles? Larry |

No, it's pretty standard.
