Old abused solid beech school woodwork bench. The littleshits (Schoolchildren) had knocked nails into the benchtop so I punched these 3/8 inch below surface and filled hole with mahogany dowl. The four holes at each corner where the vices were attached were also filled with tapered mahogany dowls glued in. They had also spent tine sawing into the edges of the bench, thesewere cut again with a saw with wider kerf and mahogany slices glued in then trimmed when glue dry.
