Faced with the choice of stripping four coats of paint from an old chair, or simply adding a new coat to spruce it up, a surprising number of normally ambitious individuals will opt for the easy way out and slap on the paint. For most of us, stripping furniture just isn't much fun so, as the years go by, old furniture accumulates finishes like a tree adds growth rings. Paint, varnish, shellac and an assortment of other finishes are regularly added until it seems that the finish outweighs the wood. However, sooner or later the day of reckoning will come. And on that day you'll have to face up to the fact that all those old coats of finish must be removed if the piece is to ever look good again. Although it may not be a day you'll look forward to, it is my hope that some of the information I'm offering here will make the job a little easier. Maybe even a little enjoyable. The first thing you'll want to do is remove anything that's easily removable. Take off doors, drawers, and hardware. If the top or legs are bolted in place, take them off, too. All these parts can be stripped separately, making the overall job easier. The next thing you'll want to do is choose your job site carefully. It must be well-ventilated and have no open flame of any kind nearby. Don't work near a gas water heater or a stove with a gas pilot light and, of course, don't smoke. Most paint removers have a high percentage of very volatile, highly flammable ingredients which give off fumes that burst into flame with the greatest of ease, For your own protection use long-sleeved clothing, a respirator designed to remove hydrocarbon fumes, rubber gloves and a face mask. Paint removers are all highly caustic and can easily burn you. There are two basic methods of removing paint and varnish: chemical and mechanical. Sanding, heating, and scraping—which fall into the category of mechanical methods—are not suitable for use in stripping furniture. Sandpaper removes and destroys the patina of age along with the finish. It also removes a thin layer of wood no matter how carefully you sand. This action changes the color of the top layer of wood, leaving a blotchy appearance that leads to more sanding until only bare wood is showing. There are several varieties of mechanical removers that use heat to soften the finish which is then scraped off. Some use a hot platen that is a combination scraper and heater. Others use super-heated air to soften the finish which is then removed with a scraper. However, none seem to do a satisfactory job. Generally, the wood surface is not adequately cleaned, and to do a good job you need a clean surface. In addition, several of these devices are actually dangerous as they can set fire to flammable finishes if the heat is applied for too long. This is especially true of those that use open flame, such as the old-fashioned alcohol and Our Modelmaker's Workbench is the ideal solution for the smaller shop. Easily made by the intermediate woodworker, the bench features a good size work surface with a tool tray and seven finger-jointed drawers for extra storage andi stability. • Detailed instructions, photos and exploded views. • Measures 34'/«" high by 50V«" long by 24" wide (not incl. vise).
