A.Kerf: The amount of material removed by the blade during cutting.

B.Tooth Set: The amount each tooth is bent left or right from the blade.

C.Gauge: The thickness of the blade.

D.Blade Width: The widest point of the blade measured from the tip of the tooth to the back edge of the blade.

E.Tooth Rake: The angle of the tooth face from a line perpendicular to the length of the blade.

F.Gullet Depth: The distance from the tooth tip to the bottom of the curved area (gullet).

G.Tooth Pitch: The distance between tooth tips.

H.Blade Back: The distance between the bot- tom of the gullet and the back edge of the blade.

I.TPI: The number of teeth per inch measured from gullet to gullet.

blade widths and radius

Blade Length

Measured by the blade circumference, blade lengths are usually unique to the brand of your bandsaw and the distance between the wheels.

Model

Blade Length Range

G8144Z.

.............................................9414"–9814"

G8145Z.

...............................................105"–110"

G8146Z.

...............................................133"–136"

Blade Width

Measured from the back of the blade to the tip of the blade tooth (the widest point), blade width is often the first consideration given to blade selec- tion. Blade width dictates the largest and smallest curve that can be cut, as well as how accurately it can cut a straight line—generally the wider the blade, the straighter it will cut.

Always pick the blade width that best suits your operation.

Curve Cutting: Use the chart in Figure 17 to choose the correct blade for curve cutting. Determine the smallest radius curve that will be cut on your workpiece and use the corresponding blade width.

The list below shows the minimum radius that can be cut by common blade widths.

G8144Z, G8146Z, G8145Z specifications

Grizzly G8145Z, G8146Z, and G8144Z are a trio of high-performance wood lathe machines designed for serious woodworkers and artisans. Each model in this series provides distinct features and capabilities that cater to various turning needs, from hobbyist projects to professional craftsmanship.

The Grizzly G8145Z is particularly known for its robust construction and versatility. It features a powerful 2 HP motor that delivers ample torque for handling both hard and softwoods with ease. The lathe's variable speed control allows users to adjust speeds from 600 to 2400 RPM, providing flexibility for a wide range of turning applications. The 14-inch swing over bed and a 40-inch between centers make it suitable for turning larger pieces, with precise control afforded by its heavy-duty cast iron bed.

The G8146Z model ups the ante with enhanced features geared toward professional woodturners. It boasts a larger 16-inch swing and a 48-inch distance between centers, accommodating more extensive workpieces. The innovative digital readout provides accurate spindle speed and position information, which enhances user precision and convenience. Additionally, the G8146Z comes with an advanced electronic speed control system that maintains consistent speeds under load, ensuring smooth operation no matter the project.

Complementing this impressive lineup is the G8144Z, a lathe designed with both user-friendliness and versatility in mind. With a 1 HP motor, it is perfectly suited for beginners and intermediate woodworkers alike. The G8144Z features a 12-inch swing and a 36-inch bed length, making it an excellent choice for smaller projects while still capable of handling a variety of turning tasks. Its easy-to-use tailstock and tool rest adjustments make setup and operation straightforward, allowing users to focus on their creativity rather than on mechanisms.

All three models come with several safety features, including a quick release tailstock and a spindle lock, ensuring secure operation. Moreover, they are equipped with robust dust ports that help maintain a clean workspace. Each lathe also supports various accessories, such as different types of tool rests and faceplates, giving woodworkers the options they need for specialized turning.

In conclusion, the Grizzly G8145Z, G8146Z, and G8144Z wood lathes stand out in their class due to their powerful motors, adjustable speeds, and user-friendly designs. Whether you’re a novice looking to develop your skills or a seasoned pro producing intricate designs, these lathes provide excellent performance and reliability for all your woodturning projects.
