The first rule of gluing wood joints is that glue does not stick to end-grain. Most woodworking joints were in fact designed to avoid the application of glue to an end-grain surface. Evaluate your joint first, and find two non end-grain surfaces that will come into contact. After making a test fit, apply glue to one of these surfaces. Spread the glue in a thin layer, being careful to not use too much glue. Then clamp the two pieces together. Use enough clamping pressure so that the pieces are held firmly together, but do not use so much force that all the glue is squeezed out of the joint. Once clamped, the pieces should be left alone until the glue sets. Setting times vary from one glue to the next, so read the instructions on the glue container.

There are thousands of plans available on the Internet, and many of them can be downloaded for free. Others are offered for a fee. You can also find plans in books and in woodworking magazines (although the magazines tend to have more complex plans). Choose plans that are simple. Although the instructor may be an experienced woodworker, the student is often not. Avoid complicated joints such as dovetails and mortise and tenons. Butt joints, dados, and lap joints are within the reach of a 12 year-old, so steer your Pathfinders to projects that use them. Use lots of pine. Pine is relatively inexpensive, and using it makes it a lot easier to start over. It can be heartbreaking to watch a youngster destroy an expensive piece of wood, and the temptation to salvage it (and thus ruin the project) can be overwhelming. Save complicated projects and expensive hardwoods for after the Pathfinder develops some skill.

The first step in finishing a wood project is to make sure all the surfaces are smooth. This is most commonly done by sanding the surfaces with sandpaper, starting with rougher paper (80-100 grit) and then progressing though successively finer grits (often to 220 grit). Sanding is only necessary if the surface is not already smooth, and some tools (notably planes and cabinet scrapers) will leave a sufficiently smooth surface so that sanding is unnecessary. In fact, sandpaper was patented in the United States in 1834, and woodworking had been going on for millennia prior to that!
