A sharp pencil is essential for making accurate cuts. To keep the pencil point sharp, rub it back and forth a few times against a sanding sheet. This will give the pencil point a chisel shape which is excellent for marking.
If you have manuals for tools and equipment scattered throughout your shop, basement or garage, putting them all in one place will eliminate searches. You can commandeer a two-drawer file cabinet for your manual center, or else consider using an older suitcase. You should be able to find such suitcases in perfect shape for only a dollar or two at garage sales or swap meets, being sold by the owners because they are out of style. Even a smaller suitcase will hold dozens of manuals and can be stored either vertically or flat.
