External keyway cutting on a lathe

I would like to cut an external keyway, on my lathe (I don't have a mill), in some 4140. The keyway is mid-shaft. I was thinking of making an adapter to mount my hand drill to the QCTP, so that I could chuck an endmill in the Jacobs chuck. Thoughts/suggestions?
 
Depending on the diameter of the shaft, you'd be better of securing it to the toolpost wither in a tool holder or something and putting the endmill in the chuck
