I like the 38 S&W case idea, I have a wood block with fired 22, 32, 38, 41 44 and 45 brass on my bench at revolver station and a small vice with aluminum jaws and a bit farther down a bigger vice with brass jaws and oak boars by it, My rod removal chuck is on a shelf right in front of me above 4 hockey pucks with various grooves and small holes to support frames. I can do everything but remove the barrel and never leave my stool unless I have to go a few steps to get onward of the parts trays. The chamber reamers, barrel wrench, dies, alignment tools are in a shortl dresser that supports that end of the bench.My gun bench is a sheet of 3/4" ply wood supported by 4 short dressers and has 2 2x12 shelves running lengthwise down the center The other side has cleaning tools and a rifle cradle. There is another 4x8 sheet of 3/4 running the other way on the end with a small drill press, a arbor press etc on the end. Across the isle from that bench is my mill and my lathe. across from the bench is another bench with knife tools dressers full of Damascus, ivory, various horn, hardwood blocks for kniife handles and on the other side of that benches divider is lots od2 x72" and a blast cabinet, grinder belts and against the wall 22 2 hp belt grinders, a flat disk grinder and 4 bench grinders on a rotating head, 3 of them set up ad buffers. The back wall has a heat treat oven and an old style dental drill with the belts. I also have one of the shaker machines and mercury silver capsules to make fillings that I have used to make silver insets on knife handles. I am a tool pack rat. LOL.
I can turn a gun into anything I want in that room.
