I'm hoping that my limited understanding off how the broaching process works
will help me find an answer. I'm lookin gfor an inexpensive way to create a
gear shift lever. My thoughts are to have a broach (if that's the right
name) made up and then utilize a press at work. People I have talked to
have suggested that using a milling machine would be the better way to go,
but that's not something I have access to. My quantities will be very low,
so the cost of having a broach made up may not be worth it. Now, here's my
application, I want to make motorcycle hand shift levers similar to the one
in the pictures below:

Perhaps another tack would be to have the pieces cut by the wire EDM
method. A CNC wire EDM machine should be able to crank this part out,
including the clamping slot in short order.

This suggestion came to mind because at the last Meeting of the New
England Model Engineering Society our speaker was Bob Bouley ,an
application engineer at Methodes Machine Tool Co. in Sudbury MA.
They specialize in Wire EDM and have, as I recall him saying, about 80
machines on the shop floor.

A big advantage of this method is that there is no tooling cost for
you. You would just have to provide a drawing and they could take it
from there.
