Ok, I was able to get this one done tonight.  Took several takes, and eventually I ran out of time so I just had to go with the best one.  Wasn't exactly how I wanted it, but it gets the point across I guess.  I'll take any feedback you have to offer, REALLY appreciate your views, favorites, shares, subscriptions, etc. 

And for some clarification, this is just over center certification, this doesn't include oil pattern certification.  Thanks again for anything you have to offer!
