Hey, Mike--you are totally right about the future refitting--it would be vastly easier and better to just install another slide, which cannot be done if the feet are lowered. Thanks for the patient tutorial! Sometimes we have to talk it through, thinking out loud in order to really understand. And taking up the slack at the top of the slider groove is key, although it occurred my way as well. I am really enthused to learn these techniques. Thanks, again...Steve
