Sorry it took so long to get back to this thread. As in measure. Yeah, I already looked up " ERTW!!!" when I first saw it under your avatar. So who is your most admired engineer? Eifel, Brunel, the two fellas that built the Hai Sophia? To bad we will never know who built the first arched structure or similar things. And if I hear about you swinging a VW of a bridge, I'm gonna tell. @gamehead- Well, you now have two vids under your belt. I include the shaking head avatar ( to bad it's now against the rules, otherwise you should put it back). Let me know when there is going to be another video release. DL
