After a quite extensive search, I have found a case that I am happy with. I wanted something as compact as possible. I found this ADG shotgun case at Academy. Its outside dimensions are 36"x11.5". The only thing I did not like about it was the foam. It had the egg-crate on top and bottom which worked just fine with my upper and lower only but not everything else I wanted in my case. The search for new foam was on.
I looked around and was about to order some foam online when I spotted some used sleeping mats at a surplus store for $5 each. After measuring them, I found that I could get four pieces out of one mat. I bought two (actually three...you can never have too many mats) and cut them into case-sized pieces.
I glued three together and made my cuts for everything that I wanted three layers deep. I then glued on the 4th layer and made cuts for a few more pieces. I tried to use a jig saw with a smooth knife blade for the cuts but found that simply using a slide blade did a better job. I just had to make sure I held the blade perpendicular to the foam.
I did botch a couple of cuts that you can see in the pics. After putting everything together and installing in the case, I found that the cutouts for the mags needed to be one layer deeper. Those cuts were not as smooth as the others because I tried to cut them without removing the foam from the case. I also found that any snags in the foam could be burned back with a lighter to look a little better.
Enough talk...on with the pics.
