Wow, pretty neat! I really, really like the step by step..... BTW, having Rick W. in your corner is a big plus... he's been there, done that, on most all of the BBL projects... We share the same facination for how the process was done in "The old days!" Looks to me as if you're right on track....More, more, more! Best to all, til....lat'r....GT
