Ok I finally had time to run the full sized part and it took a LONG time to run! It took over two hours to run and I ended up with a full garbage can of chips and a really warm spindle motor. Half way through I opened up the side cover to the lathe and ran a fan on the spindle motor to try to keep it cool as it was getting pretty hot. I'm happy with the finished part and just need to run it on the buffer a little more for a perfect mirror finish. The bummer is I still have one more part to turn!
Before I ran the part on the CNC lathe I decided to re chuck it up on my manual lathe and cut a radius on the top just to dress it up a little. I ended up grinding a custom cutter out of high speed steel to make the radius. The problem is the only way I can only hold these parts is with my 4 jaw chuck so I had to dial in both parts with an indicator before I could turn them.
Here are some more pictures.
Hopefully this weekend I can turn the second part and then make the other parts for the speakers.
