Lock, Box and Needle

This is one of the reasons I want to do Media Design over Industrial. But hey, I took physics in high school and enjoyed the engineering, so here we are. Hopefully this helps solve my locking problem for the needle combs.
I want to avoid a lock that requires pressure as I plan to use wood. Applying too much pressure too often might cause the wood to fracture. And that's not good.
Slotting the rods in and out of some kind of frame that is reset by a spring could work if the frame allowed multiple orientations of the needles. The rod holding the needles could be pulled out, twisted and released. The only flaw is that the rows could collide with each other.
Some kind of tab latch could apply pressure to one side of the rod. Not really feeling this one though...
Just another picture of a spring latch. I think I'll visit my sketchbook now. Oh dear, it's twenty to one and I have to be up at seven...
