Thanks, that is very helpful. Yes, I agree with what you say about Dave. I drove up from Houston and delivered the frame myself to Dave and we had a nice visit. I was very impressed with him personally and his work. That is why I was worried something was wrong when I stopped hearing from him. As I said above, I have something working right now through another contact resulting from my post. Let's see how it turns out. I will follow your advice if anything further is needed. Thanks again.
