Rub the Joint
One good way to ensure a strong glue joint is to use the 'rub joint' method. Simply apply glue to the edges of one or both boards and rub them together to help spread the glue evenly before clamping.
Add One Board at a Time
When you're gluing several boards together, it can be difficult to get all the top surfaces perfectly aligned. Here's a tip that solves the problem. Rather than glue and clamp all the boards at once, add one board at a time. Let the glue joint set for about 20 to 30 minutes, then release the clamps and add another board. This method will take a little longer. But it makes it a lot easier to keep all of the boards' top surfaces flush, which makes for much easier flattening and sanding of the surface.
Attach Small Pieces With Superglue
Of course you reach for a superglue (cyanocacrylate glue, or CA) to fix a broken teacup handle. But did you know that it works on wood, too? In fact, CA glue is really handy for attaching small trim pieces that would be hard to clamp. Just put three or four drops onto the parts and stick them together. We like the gel version of CA glue because it doesn't run off and make a mess.
