Hey guys, long time no talk....
I have started working on the ol' Howard in anticipation of warmer weather.
My driveshaft is the original item. When I did the resto work I had it rebalanced. It threw the weights first time out. I welded 'em back on with a MIG, trying to keep the bead to a minimum for balance reasons. Last trip out it tossed a weight again. I looked it over, and decided after 37 years a new one might be a good idea. It's nothing fancy, just has 1350's on both ends.
So the question......
Is there anything special I should know when I get a new one built? Seems like it needs to be different than a car type since it's turning around 7500 RPM.
