Hey fellas, i'm fairly new to wood working and I made a cutting board for myself and now i'm selling them on the side. All are endgrain from dense tropical woods. i'm having trouble sanding them with my belt sander and just bought a PC 2 1/4 hp. wondering if i should purchase a 13" delta planer or could i attempt planer with the router? if router what bit to use? thanks for your help!
