The garden hose valve on the left is available at Home Depot. The Steam Valve on the right, NO WAY!
The brass pieces in the rear are the "As Cast valve bodies". Cut one off, put it in the custom made aluminum holder, and it's ready for machining in the mill. The parts in front, except the handle, were made in a 1942 Atlas Lathe my father bought new for his father.
The bag on the right is what you get in the kit.
Here's the valve body in the holder. Ready to be cut and put in the mill for machining.
Another view of the Valve Bodies and holder.
The handle in it's holder, ready for machining.
Here's the instructions on how to make them.
