I have the quote from the CNC shop on lightening the spinner back plates. I can have a batch of 5 plates cut at a time. The price per plate will be $60 each and I will cover the shipping back to a domestic location. You guys in Australia will have to pay a little more for shipping if you are interested in doing this. I have one interested person so far. So we need 4 more to make it a go. Let me know via PM. Here is a picture again of the finished product. Leo
