Chuck,
I have a couple of the Timko Steel Mill books and have read through them multiple times trying to grok bits of info. I also have Dean Freytag's Bernard Kempinski's modelling books for Steel Mills. Thanks for the other ideas. I have collected links and photos of URR.
David, and Allan,
I did a few searches through facebook and weeded out the many many sites for that other big yellow RR and submitted a few membership requests. I look forward to exploring them and perhaps posting a few newb questions.
