The prototype seemed to be robust enough, but I haven't done any Finite Element Analysis yet, I'll be doing that next year and I imagine that the design will get a little more refined as well as lighter at the same time.
Cold forging is very interesting, I'm going to do some research into what the initial investment looks like to get cold forging set up for this. Also, I don't know if the finished shape could be cold forged, maybe the general shape would be cold forged and then there would be some machining of the drive side flange to get the slots in there.
