Recommended Products to Use With This Template

To make a finished Celtic knot inlay, most customers will need a way to secure the template, the right router bits, suitable wood, epoxy, pigment, and a finish for the completed piece.

• Template Tape - used to secure the acrylic template to your wood while routing the inlay pocket.
• Pocketing Bit - useful for removing the majority of the material in larger, less detailed areas.
• Small Detail Pocketing Bit - useful for smaller details, tight curves, and finer areas of the Celtic knot design.
• Dimensional Wood - choose from kiln-dried hardwoods for boards, trays, signs, panels, and custom woodworking projects.
• Live Edge Wood - a popular choice when adding inlay details to charcuterie boards and natural edge projects.
• EcoPoxy UVPoxy - a good epoxy option for filling shallow inlays up to 1/4" deep.
• Beaver Dust Pigments - use pigment to add colour, shimmer, or contrast to epoxy-filled Celtic knot inlays.
• Walrus Oil Cutting Board Oil - a good choice for food-contact boards when your project is being used as a serving board or charcuterie board.
• Grand Finishing Hardwax Oil - a great option for decorative boards, trays, wall art, signs, furniture accents, and other non-cutting-board projects.

How to Use This Celtic Knot Inlay Template

1. Choose your project: Start with a flat, stable piece of wood, serving board, tray, sign, panel, or live edge board.
2. Plan the inlay location: Place the clear acrylic template over the wood and position the Celtic knot where it works best with the grain, knots, cracks, or design of the piece.
3. Attach the template: Apply template tape to the back of the acrylic template and press it firmly onto the wood.
4. Route the larger areas: Use the pocketing bit to remove most of the material in the larger areas of the Celtic knot design.
5. Clean up the fine details: Use the small detail pocketing bit for tight curves, smaller openings, and finer areas of the pattern. Take your time, especially when working with hard or dense woods.
6. Remove the template: Carefully remove the acrylic template from the wood and store it flat for future use.
7. Fill the inlay: If desired, fill the routed pocket with epoxy and pigment. UVPoxy is a good option for shallow inlays up to 1/4" deep.
8. Sand flush and finish: Once the epoxy has cured, sand the inlay flush with the surface and apply the right finish for your project.
