Pinion + Engine Height/Angle Question

[Bradfords_garage]

Thanks Motobrewmaster for the links. I read the article and glanced at the calculators. The article seemed helpful, though I don't know how you go about determining what the harmonics will be for a given driveshaft length, rpm, gear ratio, diameter, angle...etc. Though, as an instrument builder I find it interesting.

Luckily, my uncle stopped by today to have a look at the project and he cleared it up for me. It could be level and in-line, but the misalignment is what causes the needle bearings inside the u-joint to spin inside the cup. As soon as he said it I understood something I'd read earlier, but didn't quite get at the time.

I have some drafting and figuring to do, but the links you provided were helpful, so thank you!
