Takurou Seino on Instagram: "My Secret Circle Cut Method Most routers have threaded holes for attaching guides, so I focused on that and mounted a bolt directly to the base. By securing it with an insert nut and a wing nut, you can make a simple and low-cost circle cutting jig. Using a longer bolt should allow you to cut larger circles as well. It’s easy to make, so give it a try 👍 I upload short videos every day! Please like and subscribe 🙇 @takuwoodcraft #twcdesign #woodworking
