Final Sanding and Knot Filling

What happens here

Perform a comprehensive final sanding of the entire table structure and benches. Use a random orbital sander (e.g., Festool ETS EC 150/5 EQ) with fine-grit sanding discs (e.g., 220 grit) to smooth all surfaces, edges, and blend any joints. Pay close attention to any areas that might have glue residue or rough patches. Mix sawdust (from previous sanding) with wood glue to create a custom wood putty. Apply this putty to fill any knots, cracks, or minor imperfections in the wood, especially on the tabletop, to achieve a perfectly smooth and uniform surface. Allow the putty to dry, then lightly sand again to blend it seamlessly with the surrounding wood.

Goal: All assembled components are meticulously sanded, and knots or imperfections are filled with a custom wood putty to create a seamless surface.
