Been so frustrated you wanna throw your project out??? I’m working on a walnut cutting board and I wanted to put a groove on the one side for the juices to run into, so I put a cove bit in. Practiced by running scraps through my router table and everything was fine till I went to put the groove in the cutting board. The bit jumped or caught something the wrong way and now my groove looks horrible and I just wanna throw it out except it’s a wedding present for my future in laws oldest daughter. These days make me feel like I don’t have the skill for this.
