Do you have the engineering data on the similar damper that Don Dunbar is

using?

Paul Lamar

Paul,
Yes have that! and have spoken to Don, he in turn has spoken to the
manufacturer.
Don feels it's OK but it's not rated with high enough RPM in the
literature - Don checked with the manufacturer and they said they felt it
was fine, only they hadn't tested beyond that particular rating.

Send one to me and I will see if it blows up at 7000 RPM :)

To characterize this device you usually measure the torsional stiffness
in foot pounds required to twist it one degree. Maybe Don could bring one
when he comes over and Brian could send it to me from Seattle.
I'll then compare it to Tracy's and see if it is in the same ball park.
