' THE PA.m BEACH fet' ftESIDECE5-Abvk?SIN;G! SECTION j 35 SUNDAY, DECEMBER 7, 1997 Gluing techniques often give professional results rnrrn ta info m iftsem in transfer it to the project. Your obvious reaction is to wipe your fingers either on your trousers or on a rag. Unfortunately, this generally does not remove all traces of the glue from your hands. Perspiration may keep it from drying and so whenever you touch the work piece, you risk contaminating it with glue. And this is probably the biggest reason for those ugly white spots on shop-made furniture. Glue left on the surface of the wood acts as a sealer. This means that the stain won't penetrate the wood in these areas. One trick some pros use to keep their hands both dry and free of glue is to put a box or can of sawdust in a convenient spot on the workbench before gluing. Then, as they work, they frequently pick up a small handful of sawdust, rub it between their hands and discard it into a trash barrel. The dust acts like a blotter to keep their hands free of spot-producing glue. Once glued, the work piece should be held together tightly while the glue sets. A wide variety of clamps can be used to handle this part of the job, or you can improvise. By padding the work, you can weight it with heavy books or even a cement block. The trick is to set up your jury-rigged clamping arrangement and then depart, leaving the work to dry without vibrations from working on other parts of the project or accidentally bumping into it. For smaller clamps, there are a number of make-do systems that work. You can cut sections from an old inner tube to make oversized rubber bands to hold parts. Spring-loaded clothespins make fine small clamps. Other alternatives in this area include locking pliers or even ordinary pliers with a couple of rubber bands wrapped around the handles to provide the squeeze. AP Special Features ... Many fine woodworking efforts and repairs on furniture have been spoiled because the person who did the job simply did not know how to work with glue. Two good wood glues we recommend to get the job done are white glue and carpenter's aliphatic resin glue. Both have superb holding power, but white glue gives you a bit more working time than the professional carpenter's glue. The single biggest error in gluing wood is to use too much of the stuff. Excessive glue actually produces a weaker joint. The correct way to use glue is to spread a thin layer on both surfaces to be joined, let the glue get tacky to minimize sliding action and then press the pieces together. Except for contact cement, you should apply clamping pressure immediately and let the piece rest at least 24 hours. Wiping off the excess glue that squeezes out of the joint is the wrong thing to do as there will be an almost invisible layer of glue left on the soft and absorbent wood surface. You may not be able to detect it before staining or otherwise finishing the piece, but watch it pop up as soon as stain is applied. The correct method for removing excess glue from a joint is to let the welt of glue dry untouched. Then, carefully remove it with a razor-sharp wood chisel, bevel edge up. Hold the blade edge at a slight angle to the glue line to remove flakes of hardened glue as you slice them off the joint. Follow up by sanding the joint with a piece of 120-grit paper backed up by a wooden block. Glue spots on your projects can be another problem. They commonly appear when you get, glue on your hands and Keep the refrigerator clean 4IS3 tor can cost you a lot of money on your utility bill. . The first step in the maintenance process is to determine what kind of condenser your refrigerator has. It either has a static condenser mounted on its back, or it has a fan-cooled condenser mounted underneath in the compressor compartment. The fan blows air across the condenser to cool it. In the case of a fan-cooled condenser, first unplug the refrigerator and then remove the front lower grille cover (on most models this is held in place with spring clips). There is often a small tag on the cover's top edge that states how often the condenser should be cleaned or inspected (usually every three months). Clean the condenser using the crevice tool attachment on your vacuum. After vacuuming, check that the condenser is clean by shining a flashlight through its coils. Vacuum the coils clean from the back. If need be, use a paintbrush to dislodge dust that the crevice tool did not pull out or that was pushed toward the back of the appliance. AP Special Features The condenser is an important part of your refrigerator's sealed refrigerant system, and it is the only part that needs maintenance. Here's why it's important to keep the condenser coils clean: The condenser cools hot refrigerant vapors inside its tubes. If the condenser coils are dust covered, they cannot expel this heat efficiently. The dust acts as insulation and prevents the heat from escaping. In turn, the temperature inside the refrigerator compartment is higher than it would be if the condenser coils were clean. This increase in temperature also causes the compressor to cycle refrigerant through the cooling system more frequently than it otherwise would. Not only does this increase the amount of energy the compressor uses, but the additional waste heat given off by the compressor further reduces the refrigerator's efficiency. Efficient cooling, therefore, is the ability to pump heat out of the refrigerator using as little energy as possible and creating minimal waste heat. Looked at another way, a little dust on your refrigera
