Hello everyone, I came up with and created a unique shelf. One shelf, but many options. I put off this project for two years and finally got to it.
Everything can be. But I took well-dried wood, opened with ponotex and two layers of festool oil.Pretty clever.
I imagine with board wear over time and changes in humidity etc these shelves may become or too lose to properly sit in whichever random location you choose.
I say multiple screw holes in each shelf board for the various configurations is probably necessary to make sure they stay securely in place.
