Hi Kelly;
Unfortunately, no updates to report. Life in general is just too busy. I recently just got caught up reading the list as I was over 2000 emails behind. I'd like to say that I'll get back to it soon, but in reality I have so many other things ongoing and other things upcoming that I just can't make any promises. But I do try to keep up with reading the list as this project is something that is still very important to me.

Todd,
Speaking of your PM alternator installation do you have any updates to report ?......

Early drives like Tracy, Ed, Bill Eslick(? havent heard), Todd Bartrim (havent heard), Chuck Dunlap (havent heard), Tommy James (havent heard) and I (so far) don't seem to have a problem while you and Mark who have slightly later versions are having loosening. (Have we heard from John Slade or Steve Brooks and I missed it?) Any other high-time re-drives that I left out?) - What about Tom Parks? (turbo 20B with Ross Drive). It's possible that power is the main issue (average torque), but it seems to me that peak torque and torque variation amplitude are what are going to matter most. You and Mark are going to have lower peak torque than those of us with turbo engines, and with 20B's you are are going to have lower torque amplitude than even those with n.a. 13B's. Only your average torque is higher. Seems strange... that is why I am wondering about some sort of change to the later mod
els of the gear drive. Tracy?

Hi Dave;
When I disassembled my plate to install the PM generator rotor cup, I did notice a couple of minor smoke trails from a few of the rivets, However when I drilled them out for disassembly, none of them spun with the drill bit, indicating that they were still tight. Since this is something that I've modified from the original design, I'll certainly pay close attention to it now.
Todd
