Thanks for watching, K

Update: It's a bit surprising to me that this video is by far the most viewed of my videos. The parts are just examples I made one afternoon while messing around in my shop to demonstrate the capabilities of lost foam. The same is true of my "Saucer Cup and Spoon" series. But IMO, the parts in some of my other videos represent much higher casting accomplishments. Best, K
