There are various types of clamps available and choosing the correct one will ensure your can complete the project easily. Using clamps do require a bit of care so you need to follow the below guidelines.
- Always use a piece of scrap wood between each jaws of the clamp and the workpiece to prevent damage.
- When a clamp is positioned, close the jaws until the clamp feels tight, when gluing, some will be squeezed out around the joint, a sign that it is tight enough.
- Clamping pressure should be applied at right angles to the glue line otherwise slippage may result.
- Do not over tighten; if the fit is accurate only moderate pressure is required, the purpose of a clamp is only to maintain uniform pressure between the two surfaces, not to force them to fit.
G Clamp. Sometimes referred to as 'C-clamps'. Probably the most widely used and versatile clamp. It can be used to clamp a workpiece to a work surface or two parts of a workpiece together. Jaw openings range from about one inch to over 8 inches. The end of the screw section normally has a swivel head which enables the clamp to sit on irregular surfaces.
Pipe Clamps. These are very similar to the Sash cramps but using a round shaft instead of the flat bar. The length is determined by the length of the pipe used, they can be lengthened by adding additional length of tube.
Bench Clamp. 2 piece bench clamp which are designed to fit workbenches with holes 18-38mm. Clamping range 0-80mm. Those shown include quick release clamping action.
Nyon Band Clamp. Ideal for frames. The Nylon band wraps around the object and is tightened with a ratchet. Can be used with (or without) corner gripping pieces (as shown) so that pressure is evenly distributed.
Mitre Clamp. Used for gripping two pieces with mitred ends at right angles. Two types are available, internal (upper) or external (lower).
Quick Action Clamp. One hand operated clamp (operates like sealant guns) ideal for quickly and easily clamping all kinds of workpieces. Simple single finger release.
Quick Grip. Features one-handed operation with adjustable pressure, best for thin pieces as the jaws do not close square.
Screw Clamp. Fast and powerful closing / opening due to special thread and handle grip.
Speed Clamp. A metal bar with serrations. As the clamping pressure is applied the serrations lock & secure the sliding head.
