There are a many choices to make when choosing glue. Here are some of the most common: 1) White glue is the most popular choice for general purpose adhering. It's non-toxic, odorless, nonflammable and dries clear in under an hour. One drawback of white glue is that is has a low resistance to water, so it should not be used for outdoor projects. 2) Yellow carpenter's glue sets quicker and is more resistant to water than white glue. It won't be affected by solvents used in woodworking such as varnish, lacquer, or paint. Yellow glue dries to a translucent finish but can be sanded. 3) Hot-melt glue is applied with a glue gun. It sets almost instantly on wood, metal, cloth, and ceramics. There are several formulas available for you to match to your project. Hot-melt glues, however, do not adhere well to cold surfaces, so make sure that your workpieces are not cold. 4) Instant bonding glue is incredibly strong and sets almost instantly. It is ideal for non-porous surfaces such as glass, certain plastics, ceramics, and metal but can also be used to bond wood and paper as well. If you should accidentally drip some onto your skin, use nail polish remover to dissolve it. Instant bonding glue will dry inside the container very quickly so be sure to tightly replace the glue container's cap as soon as possible.
One problem in using older-style pegboard hooks is that they tend to pull out when the tools are removed. One way you can solve the problem is to insert them into the pegboard and use a hot glue gun to fasten them in place. In a minute or so the hooks will be fixed in place, although you will be able to wrestle them loose whenever you want to rearrange your tool storage. Another solution is to buy newer-style hooks that will lock in place with just the turn of a screwdriver.
If you are gluing veneer to a wood surface, you can use an old clothes iron to help. First use a sponge to wet the face of the veneer so that it won't curl. Next, apply a thin film of glue to both the surface and the underside of the veneer. Then, when the veneer is dry to the touch, use the clothes iron at a high setting to secure the veneer in place.
Glue will soak more into the end grain of wood and can potentially result in starved glue joints. To help prevent this, you can "size" any end grain to be glued with a mixture of glue diluted with water. Dilute just so that when it is applied, glue drops don't form at the lower edges of the wood. Another method, somewhat less effective, is to coat the end grain with full-strength glue, allow it to dry 5 to 10 minutes, then re-coat with glue and assemble.
You can cut the cost of wood glue for workshop projects significantly by buying your glue in 1-qt. or larger containers. To make it convenient to use, transfer the glue as you need it from the large bottle to your own squeeze bottles or a glue pot.
Using thin wood wafers called biscuits can strengthen wood joints by providing more glue bonding area. You can use a biscuit joiner (also called a plate joiner) to cut precision mating slots in boards for the biscuits, which are available in three sizes. Or, to save money you can buy a kit to convert either your router or right-angle grinder. The conversion kits will generally cost about half that of a dedicated biscuit joiner.
One way to fix a loose screw in wood is to remove it and then insert toothpicks or burned wooden matches with a coating of wood glue into the hole. Allow the glue to cure, then cut flush and re-drive the screw. You can also insert a plastic wall anchor into the screw hole. When you put the screw back in, it will expand the anchor and will hold solidly.
Do you have any chairs, tables, or other wooden furniture that are a little wobbly due to the glue drying out? Here's how you can tighten things up. First, disassemble the joined pieces. Clean off all of the old glue and dirt with warm vinegar. Rinse with clean water, and let everything dry completely. Use yellow carpenters glue to reassemble all the pieces back together.
Warm vinegar will generally soften the most stubborn old glue on old furniture. Dipping the parts to be reglued in warm water, and then letting them dry out completely, will help to open up the wood pores and allow the new glue to enter the wood more freely. Warming the parts on top of a heater or in the sun will also help open up the pores of the old wood before regluing.
When clamping long or wide panels with bar clamps, a dowel inserted crosswise between the jaws of the bar clamps and the wood will help center the pressure and keep it uniform. Use dowels about as thick as the thickness of the wood you are gluing up.
