If you don't have a vertical mill, or at the very least a good drill press and a good XY table, you won't be able to do it no matter what kind of jig you have.

And if you have a mill, it would probably be easier and quicker to just make your own jig...

That's the key. It's not so much the bolt holding fixture as it is being able to index it with some level of precision.

There are cheap x-y tables available, but the problem is they are usually sloppy with a lot of backlash, and the travel is not precise. You often have to get a dial indicator in order to use them. And you can't back up during an operation because the backlash throws everything off. Travel in one direction only when doing work.
