12 Tips for Successful Gluing
by Tom Caspar
Do a Dry Fit
Clamp your pieces without glue to make sure the joints come together tightly. This step also serves as a test for your choice of clamps and blocks. Here, a dry run revealed that I need wedge-shaped strips and a spacer to clamp these tapered legs.
Prepare the Glue Brush
If you use a brush, remove any loose bristles. Acid brushes are inexpensive and work well, but you should cut the bristles to about half their length to more easily control where the glue goes. You can find these brushes at a hardware store.
Prepare a Cleanup Tool
It’s best to remove glue squeeze-out before it hardens. Use a clean putty knife on wide surfaces and a freshly sharpened stick in corners. Wipe them often on a damp rag.
Protect Your Wood
Small clamp heads can put big dents in your project. Make sure you’ve got blocks, strips or pads handy to place between the clamp heads and the project’s parts. I prefer to make blocks from a soft wood, such as pine, to avoid crushing my project.
Avoid Black Stains
Iron pipes leave black stains on your wood if they directly contact glue squeeze-out. Run a strip of masking tape along the length of each clamp to prevent this problem. Galvanized pipes don’t require taping.
Fix Too-Tight Joints
If you must pound parts together, the joints are probably too tight. Tenons swell a bit when you add glue, which makes a tight joint more difficult to assemble. The most accurate way to pare a tenon is using a rabbet plane. Its iron is the full width of the plane’s body, so it can cut up to the tenon’s shoulder.
Clean Your Bottle’s Applicator
If your glue bottle’s cap is clogged with congealed glue, soak it in a jar of very hot water for 15 minutes or so. This softens hardened glue, making it easier to remove.
Check the Glue
If you’re uncertain about your glue’s age, test its bond strength. Glue together two small scraps that are each about 1 in. wide, clamp and let dry 24 hours. Hit one piece with a hammer. If the two pieces shear apart with no fibers from one piece stuck to the other, your glue is probably too old. Replace it.
Arrange Your Clamps and Parts
Keep handy all the clamps and blocks you used in the dry fit. Arrange them so each is oriented correctly. Place all your parts in a logical order, so you can assemble them in sequence. Just remember—don’t panic.
Adjust Your Clamps
Make sure your clamps are ready before you glue. Unscrew the handles until you have a maximum amount of thread available. Sticky clamps can slow you down. Slide the sliding head on a small bar clamp or the tail stop on a pipe clamp to make sure it moves freely.
Get Ready for a Mess
A cotton rag and a jug of warm water are handy for wiping up spilled glue or lots of squeeze-out. I cut out the side of ...
