Shaper Keyway Cutter for Pulley

[Black Forest]

If you don't mind I would like to know how you fix the cutter in the shaft? Do you have an end bolt pressing against the cutter? What I don't understand is why you didn't just drill a hole and use a file to square it up to fit the cutter. It just seems like a lot of extra work to use the shaper to cut the slot and then weld on an end cap. Or am I misunderstanding what you did?
