Is that like all squares are rectangles, but not all rectangles are squares? impellers (sans radial flow types) are propellers....but not all propellers are impellers. o_O:p

I'd sell my glass hull one for the right offer. PM me if interested. :)

Flat, but a 100% chance of fizz.

Only one of those pictures is clear enough to really tell anything...but my nerdy bored on a Saturday morning over engineered 2 cents... Assumptions: 1) There is an obvious stress riser where the small stem diameter meets the larger boss/spring locator. A larger fillet radius here would help...

False. I can answer in more detail later when im not at work. All we know is it failed along the plane of maxium shear. Really need a closer picture to determine failure mode and propagation. Torsion failures of ductile material and fatigue failure look an awful lot like a tensile failure of...

Being aluminum... I'm pretty confident one could do some damage with just an allen wrench.

Since when? He was still there like a month ago... Can you take a picture of the face of the fracture? We may be able to tell you the failure mode. Seems like it propagated from the stress riser where the small diameter stem meets the larger diameter...but why? May have started from over...

Wheres the "dislike" button?! Boo!! Tell the fam we'll miss them!

Joey does top notch work. If you want it plug and play, i wouldn't hesitate to have him set it up for you!
