Most short sections of boards can be resurfaced using a CNC router. warps in the wood are hard to resolve when the piece is short. Use a large router bit or fly/surface cutter to resurface and use. Once the surface is planed, leave it clamped and make a project out of it.
You can flip the board after to resurface the backside.
This project was done on BobsCNC E4.
Please leave a comment on how you manage warped end pieces.
