I'm thinking of making an impulse starter for my 1910 Mitchell from a set of patent drawings of one that was invented around 1906. The major stumbling clock is that it has to have a tapered hole in order to fit the magneto. The taper is one originally used by Robert Bosch and later adopted as the SAE standard. Here's the pages from the SAE handbook describing it... The specs for automobile magnetos are on the first line of the chart.

I was thinking of a tapered end mill but I can't find one with the correct 11.5 degree taper. Is such a thing available? Or, if not, what might be a good way to go about this.
