Top piece of kit
It's a very cool piece of kit. There are tons of YouTube videos that show how to make your own jigs but the accuracy and flexibility (and I don't mean bendy) of this are unbeatable. I could do with it being in metric and not the American ancient history imperial measurements but I can live with that. Cutting out the circles in the photo was easy and actually really satisfying. Strongly recommended.
