Fenton,

Are your asking a question? If you're asking to recommend a bit to do the job, go to mcmaster.com they have dovetail bits that would do the job.

I think the proper router bit would be called a key hole bit which will make a hole for the screw head and a slot that allows the slip to be seated in front of the keys

Roger and James, Thank you for replying. Key Hole bit, yes! I used to do some dove tail work and I'm not sure that

would be my first choice. McMaster-Car is indeed a great resource, but one needs to know what to ask for.

Please excuse my poorly word original post including ' screw in the key slip' it is of course in the cheek block.

Also, I've been way off the grid lately, just getting back to see my responses. HNY.

Fenton,

If I understand you correctly.  A typical configuration you mentioned is going to be a # 10 flat head wood screw mounted on the cheek blocks with a dove tail slot in the key slip. The typical configuration for that application is a  #10 wood screw with a 45-degree chamfer and a head diameter of about 3/8". The McMaster tool for that would be 2984A17. But I've been wondering if obtaining that dove tail bit may not be your greatest challenge. To accomplish the chamfering task requires you to have a holding tool for the key slip and a means of holding the tool with the dove tail cutter. Both require firm holding techniques such as a milling machine. I can't imagine how you could perform that action without a milling machine type arrangement. I can visualize terrible results otherwise.
