Clean and Refine Drain Hole, Install Hardware

What happens here

Thoroughly clean out all sawdust and wood debris from the newly drilled drain hole and the interior of the sink basin using a shop-vac. Once cleaned, use a wood chisel and hammer to fine-tune the edges and depth of the drain hole, ensuring a perfect fit for the chosen sink drain hardware. Finally, insert the drain hardware into the hole to verify a snug and flush fit. The drain is made of polished stainless steel and includes a removable strainer.

Goal: Ensure a clean, precise drain hole and confirm proper drain hardware fit.
