So CSX Al, does your turntable magically adjust to different plywood widths used by builders? Does it magically adjust based on whether or not the installer uses homasote on top of the plywood? Methinks you brag a little too much about how easy installation is.
Chuck, like Al says above the turntable has 1.5" of adjustment. If your plywood/homasote, cork, foam, whatever sandwich is less than that thick then his table will fit fine. Given my experience with Al, if your sandwich is thicker than that then he can custom-build a turntable that will fit your sandwich. Methinks he tells it like it is. As someone in the sports world once said, "If it's true then it ain't bragging."
