Types of Wood Edgers
Manual Edgers
Manual edgers are often the most basic type of wood edger, designed for small-scale operations. These machines require manual effort to feed the lumber through the blades. They are ideal for hobbyists or small woodworking businesses looking for an economical solution. While they offer limited capabilities, they are cost-effective and straightforward to operate.
Hydraulic Edgers
Hydraulic edgers are well-suited for medium to large sawmills that require a higher production rate. These machines utilize hydraulic power to automate the feed process, significantly increasing efficiency. With the ability to handle wider boards and thicker lumber, hydraulic edgers can produce a large volume of finished product in a shorter time frame.
Twin Blade Edgers
The twin blade edger, such as the Wood-Mizer EG200, is designed for high-volume lumber processing. Equipped with dual blades, this machine allows operators to edge two sides of a board simultaneously, effectively doubling productivity. The EG200, in particular, boasts the capability to handle boards up to 24 inches wide and is powered by either gas or electric engines, making it versatile for various operations.
Linear Edgers
Linear edgers are optimized for hardwood processing, utilizing advanced technology to maximize yield. The McDonough OptiFit Linear Edger, for instance, is designed to fit into existing sawmill setups without requiring additional space. These machines are perfect for sawmills looking to enhance their efficiency while maintaining superior cutting accuracy.
Customizable Edgers
For operations with specific needs, customizable edgers offer tailored solutions. Manufacturers like Sawmill Supplies provide custom-built machines that can include multiple blades and adjustable speeds. Such flexibility ensures that sawmills can meet their unique demands while maximizing productivity.
Key Features to Consider
Blade Types and Sizes
The type and size of blades significantly impact the performance of a wood edger. Carbide-tipped blades are commonly used for their durability and cutting efficiency. When selecting a machine, consider the maximum board width and thickness it can accommodate.
Power Source
Wood edgers can be powered by manual means, hydraulic systems, or electric/gas engines. The choice of power source will depend on the scale of operations and the specific requirements of your sawmill. For example, hydraulic edgers are suitable for high-demand environments, while smaller operations may benefit from manual or electric options.
Feed Mechanism
Automated feed mechanisms, like those found in hydraulic and twin blade edgers, enhance productivity by reducing the need for manual operation. Features such as adjustable feed speeds can further optimize the edging process.
Safety Features
Safety is paramount when operating heavy machinery. Look for machines that include safety guards, emergency stop buttons, and anti-kickback features to protect operators during use. The Wood-Mizer EG200, for example, is designed with a protective guard and an emergency stop button for added safety.
Durability and Maintenance
A wood edger should be constructed from heavy-duty materials to ensure longevity. Additionally, consider how easy it is to maintain the machine. Features like easy blade changes and accessible lubrication points can save time and effort in the long run.
Technical Features Comparison of Wood Edgers
| Model | Power Source | Max Board Width | Max Board Thickness | Blade Type | Feed Speed | Safety Features |
|---|---|---|---|---|---|---|
| Wood-Mizer EG200 | Gas/Electric | 24” | 2” | Twin carbide-tipped | Up to 70 fpm | Protective guard, emergency stop button |
| Riehl Steel Board Edger | Gas | 23” | 2-1/4” | Carbide-tipped | 50/70 fpm | Undersaw guard, anti-kickback fingers |
| McDonough OptiFit Edger | Electric | 19” | 2” | Linear carbide-tipped | Up to 40 pieces/min | Safety interlocks |
| Hud-Son Hydraulic Edger | Hydraulic | 24” | 3” | Carbide-tipped | Variable | Safety shields |
| Morgan Edgers | Customizable | Varies | Varies | Custom blades | Adjustable | Custom safety features available |
