Ah this is no sweat for you now bro. Sucks but it does bring a sense of excitement. I just found a crack on my rear iron AND I TOO am excited about this new little hic-up.
It is nice to know that your blow out was from a simple brain fart and NOT some unknown mechanical bad joo-joo failure. Much better luck 4 you given your past head aches.
I have come to the realization that this is what comes with DIY high HP rotary tuning/building. Deal with it or go home.
Good luck with this build bro.
