I don't know why I picked tonight but I did and it runs. Nothing dramatic, no unusual noises, it runs smooth. I will finally drive the "Southern Seven" Monday or Tuesday. It only took 6 years.
I'm willing to put $200.00 into a set that would stay in the D.C. area that could also be used at events. I agree that they would not last long if they were passed around between too many people.

If your going to purchase a torque wrench make it a 1/2 in. Fixed, Nonratchet Drive beam-type torque wrench.
I purchased one when I was, well let's just say over 40 years ago and it is still accurate. Look on ebay.
You need to do a little research on drive shafts and critical speed. There are many web sites with calculators.
The critical speed of a spinning shaft is described as the lowest speed which excites the shaft at it's natural frequency of vibration. This will cause the shaft to bend under the stress of vibration coupled with the centrifugal forces due to the rotation. In english, this means the shaft will vibrate very badly and possibly take a permanent bend (if not destroy the car in the process) as the critical speed is exceeded.
Thanks:
Al for your "great" admin and marketing skills, Mazda for the concept, Russ for my first ride, Scott for my second ride, and everyone else for your warm conversation.
