Tool idea

I’m thinking it would be fun to build a weapon display case, not only for my bayonets, but also for the more mundane weapons of my hobby. Probably start with a sheet of plywood, and some stripping all around, embed LEDs, and a liner of velvet. Then it’s mounting time. I need elegance and strength. At first, I could use some probably stained dark, doweling. But I don’t think I want to rebuild the wheel over and over again.
I should look into which tools are going in and go from there.
