Frequently Asked Questions (FAQs)
1. What are the advantages of edge clamps?
Edge clamps have several advantages over wedges. They provide pressure at two separate spots, doubling the number of clamps. They also have some springiness, allowing them to stay tighter. Additionally, they can be used with bits of scrap wood, eliminating the need for wedges.
2. What clamps hold wood while cutting?
There are several types of clamps that can hold wood while cutting, including corner clamps, strap clamps, trigger-activated clamps, wood screw clamps, spring clamps, and parallel-jaw clamps. These clamps provide stability and secure the wood in place during cutting tasks.
3. Are pipe clamps stronger than bar clamps?
Pipe clamps are not only cheaper than bar clamps but also allow for higher clamping pressure. A typical parallel clamp can reach about 370 pounds of pressure, while 3/4" pipe clamps can reach 1,050 pounds, and I-beam style bar clamps can reach 1,350 pounds.
4. What types of clamps do you use for edge gluing panels?
For edge gluing panels, specialized clamps like pipe clamps and parallel clamps are commonly used. These clamps are designed specifically for gluing the edges of two or more boards together, ensuring a secure and stable bond.
5. What is the best adhesive for edge banding?
Most edge banding is applied using hot melt glue. The two main choices for hot melt glues are EVA (Ethylene Vinyl Acetate) and PUR (Polyurethane). These adhesives provide strong and durable bonds for edge banding applications.
6. Do you sand before edge banding?
It is recommended to sand the edges of plywood smooth before applying edge banding. Sanding helps to remove any saw marks or roughness that could prevent a strong bond between the edge banding and plywood. Using 120-grit sandpaper wrapped around a small block of 3/4-inch can help achieve smooth edges without rounding them.
