Murphy has just popped his head out again! Drilling my last hole in the center hole. the pane chipped out big. Here are some pic's. Most likely I can not us this bottom pane. I have a spare piece of glass, but it has to be cut, and drilled. It is L48XW24. So I could get the bottom pane and the top bracing out of it.
I guess it is time for a Jager and 7!
