That is actually a great idea. They fit the profile perfectly.
They sure would be better than what we can cnc plasma.

I know that 948 had an arm with brakes on it. This was a while ago though, maybe 2005. I think they did something based on bicycle brakes.

That is what we are planning to do. Use a disk brake caliper from a bike and now a plate sprocket to keep our elevator stationary.

Here are a couple of views of how we used a disk brake for our 2011 winch controlling the should joint of the our scoring arm. We used brake cable and short stroke pneumatic to actuate it. It is all mounted on an AndyMark toughbox.
