Ned,
You should consider existing brakes first. Reinventing the wheel rarely makes economic sense. Check out Kobelt
Manufacturing...they are excellent.

Thanks, Steve, I looked and didn't see anything I could use now. Quite
likely there's something there that would have worked if the safety
was designed in from the start, but as I mentioned elsewhere, this was
a supposed to be a prototype and only to be run to prove out a
concept. Not so anymore.
