Product cuts great and does what it's supposed to. But it also does something else. Look at picture 2 which shows a groove carved into the wood of my template. After cutting out my loop layout using a stencil, I noticed a groove in my stencil. Upon closer inspection, I noticed that the bolt that was supposed to hold the wheel in place was sticking out of the wheel. It was on both bits I brought (14151q and 14122q). It was an easy fix. I just sanded both (picture 1) flush with the wheel. But QA had to catch it. These are great beats but I don't need to finish them before using them.
