Looks good, but how will it work? Only one way to find out, take it for a spin:

The Susan spins freely and the center screw stays centered as it spins. This means everything lined up well. I let out a huge sigh of relief once I see that!

The arms (big-ass arms, Shells wants this thing to be able to handle a 100″ circumference hank) will attach to that screw. Those get started tomorrow…
