This jig is worth having because it turns your router into a slab mill that actually feels stable and precise. Instead of fighting high spots with a hand plane for hours, you can glide the router across the surface and get a clean, flat panel ready for sanding and finish. It is a game changer for tables, countertops, and any wide stock you cannot run through a planer 🔥.

✅ Carriage features removable plate for easy mounting of router, plate secures to carriage with four knobs
