Motorized Vehicle Display Cases

[Super]

Update:

Here is what I have come up with for displays. First...the Train shelves were raised up because when they were originally installed my Grandson was quite small and I wanted to keep them low so he could reach the trains. The smaller shelves with clear dust free acrylic fronts I have had for quite some time. All the vehicles on the right side is our collection of motorized vehicles. The left side holds some of our favorite Hotwheel, Matchbox, Tomica non-motorized vehicles.

Both the train shelves and the Diecast car displays were made by the same fellow in Wisconsin, USA. I wanted to purchase two more so I could display more of the Diecast vehicles but he no longer makes them or has a website. I am still trying to track him down to find out if he has some additional stock I could buy. My fingers are crossed hoping he does and since he made them in a shop at his home, maybe I could offer him something to make me a couple.  I do have an idea of how to modify the train displays with a sliding piece of clear acrylic panel to hold out the dust. I have the correct size aluminum U channel for the slider tracks but I am trying to figure out how to attach it. Anyone have an idea of how to attach or know of a glue that is great for attaching aluminum to wood? I still have to find a source of the clear acrylic somewhere near me. I am sure it won't be cheap.
