When making repairs or taking apart equipment, be prepared for the occasional dropped part. Clean off a section of your workbench and spread out a smooth shop or dish towel. The towel will keep errant small parts from rolling around on the floor and getting lost. For small jobs, even square shop rags will work; for larger jobs cover the bench with salvaged carpeting.
Here’s a way to save time and energy when repairing floorboards. Instead of drilling and chiseling damaged floorboards, use a plunge router. First, use a magnetic nail finder to be sure there are no nails in the way. Set scribe lines across the damaged pieces. Then, run the router across the boards for a quick, clean cut.
