I got tired of having multiple sheet metal gun cabinets, one Stack-on long gun cabinet, one Stack-on pistol cabinet, and another long gun cabinet I bought used. I wanted something bigger, and a little more secure, without going to a full blown safe that's the size of a small van. I did a little searching and saw something that some guys were doing. I thought it was a good idea and I like building things, so I set out looking for the perfect starting point. A week later I had what I was looking for. After a few days of gutting, cleaning, carpeting, and accessorizing, I ended up with this. It may not be as secure as a safe but it is a lot more stealthy (blends in nice with my slot machine and other stuff). It is more secure than the sheet metal cabinets though. The door has a nice gasket to seal out moisture and it is insulated so it should give some heat protection even though it's not fire proof. The area where the compressor was can hold a lot of ammo cans. I'm really happy with the way it turned out. Now if only I had a gun to put in it (damn boat accident).
