A problem for those in northern climates is the constant hassle of moving tools from garage to basement in the fall and back again in spring. Newer roll-away storage chests, project centers, utility carts, and wheeled tool boxes provide portable storage to make the job easy. Rolling tool carts with extendable handles like carry-on luggage also let you divide tools according to the project and wheel right to the job.
Need to replace your trusty old level? You can check it for accuracy. Lay one working edge on a flat surface and check the bubble. Swap it end for end, then check the bubble again. It should be in the same position. Now try the opposite working edge. Take a reading, switch end for end, and take another reading. The bubble should be in the same position. Likewise check for plumb by holding it against a flat vertical surface.
