Sand and Fill Panels

What happens here

After the glue has fully cured (ideally overnight), the clamped panels are removed and prepared for sanding. A random orbital sander (Festool Rotex RO 125 FEQ is demonstrated) is used to meticulously sand the surfaces, starting with a coarser grit and progressing to finer grits (up to 220 grit as mentioned by the creator) to achieve a perfectly smooth finish. This step also involves using epoxy resin to fill any knots or voids in the wood, creating a smooth and consistent surface. Blue painter's tape can be used around the knots to contain the epoxy while it cures.

Goal: The glued panels are thoroughly sanded to remove excess glue and smooth surfaces, and any visible knots or imperfections are filled with epoxy resin for a uniform appearance.
