I just put a triplay board on the wall and used screws on it… to enhance the board a bit i covered it with a perforated metal sheet which also serves as a guide for positioning the screws.
It´s a relatively inexpensive solution, looks ok and does the job.
Have been thinking of putting a Dannmar M6 in my garage one day so I took some measurements today and rolled a project car (Karmann Ghia) into place.
I now have two boxes, one on each side aproximatley where the posts would be, this so i can see how practical it will be to even have all that...
