I am conficted with regards to mr fast fred. On one hand I had a number of very productive conversations with him about headwork, both practical and theoretical (that I was able to put to good use), then on the other hand, I have a pile of 36mm CVKs (that I bought for cores)and custom made balancing screws and over size butterflies, etc... setting in my shop, as well as the machining fixtures, all waiting on a deal that never came thru.
