Hello everyone, this is Rani. I’m still in my first year of woodworking. I made a cutting board and I ran into two problems: 1- While planing it, I realized I can’t use my hand planer in both directions. Some parts of the wood got chipped out, and I think it’s because I glued the strips in opposite grain directions. So if I go one way, I ruin the adjacent strip. 2- I used a router and guided it with a piece of wood to make a shallow groove around the frame, but it didn’t come out straight. Then when I tried going slower, I ended up cutting too deep in some spots. Any advice would really help, thank you
