Selfbows

I made this workbench yesterday. No nails. The top is OSB with 2x4's screwed on from the bottom. I always seemed to hit a nail when cutting leather on top of a workbench. I'd like to get a plane and smooth the top a little. I need to anchor it to the wall and probably will put end plates on the side to stiffen it more. It's the height of my bandsaw. My chest of drawers I use to store arrowmaking and bowmaking stuff will fit under
