Skeater, I have used that same jig. It works “ok” but you need to make sure your limbs and riser as parallel as possible! You will also have to draw a center line on the limbs before you mount them to verify they are mounted straight. I’ve also had to swap them top and bottom before to get them lined back up. It’s not perfect but it’ll work with some patience. I am in the process of having a new jig machined and mounted to a machined surface to expedite the process.
