I have a question though, If you can cut the keyway into delrin, why can't you cut it into Aluminum? You have a laser cutter, right?

Any chance you could post screenshots of your FEA results? What was the total deformation?
Our laser cutter can only cut plastic, for the most part. It has a hard time with polycarbonate, as it scores the edges, and melts polyethylenes, for example. It cannot cut reflective materials at all and just isn't powerful enough to get through metal of any useful thickness.
On the other end of the spectrum, our plasma cutter can fight through 1" thick chunks of steel, but its kerf is pretty bad and it does a bad job of cutting fine details in parts. For example, holes almost never end up being round by the time it's done
