Here is a picture of my castings and patterns for the bed and the feet. The pattern for the feet was machined completely on my CNC router. For the bed pattern, I used a table saw to cut the outside profile and used the CNC to cut out the inside pockets. Both patterns feature 3/8" wall sections and are made slightly taller than what Gingery describes in his book.
My sand was too dry when I cast this foot. You can the the void in the fillet area from washout. The second image is where the sand ended up. I wasn't happy with this casting so I made another to replace it. Maybe I'll use it as a center support on the lathe.
Here is the machined bed sitting on it's feet. I have access where I work to a Bridgeport mill and a CNC machine. I used a 4" fly-cutter to face off the top and bottom of both beds that I cast as well as the feet. The second image has the ways bolted on.
