Congratulations, Dennis!!! That is a really sharp looking installation, besides the fact that it works beautifully! I see the alignment pins in the bridge and the holes for them to fit in.
As an interesting aside, our younger daughter was over last week and took a video of mine in operation. Thursday, I saw a friend of theirs at the grocery store. He told me she had shown the video and he was impressed enough to tell me. I told him I got the concept for mine from a friend in Washington, mike g. Mike, how do you like Dennis' bridge?
