6.Position the back edge of the blade so that it is next to, but not against, the flange of the top wheel (see Figure 22).

Note: Excessive blade contact with the wheel flange during operation could lead to blade and wheel damage.

7.Rotate the top wheel by hand several times to make sure the blade tracks evenly without wandering across the wheel surface.

Note: If the blade does wander across the wheel and away from the flange, the wheel alignment may need to be adjusted. Refer to Wheel Alignment on Page 42 for detailed instructions.

8.Re-tension the blade (refer to Blade Tensioning on this page).

9.Check the upper and lower blade guides for clearance (refer to Adjusting Blade Guides on Page 31).

Note: Generally if the replacement blade is the same gauge, width, and type, blade guide adjustment is not necessary. Otherwise, you must adjust the blade guides.

10.Close and secure the upper and lower wheel doors.

Blade Tensioning

NOTICE

To prolong blade life, release the tension on the blade if the machine will be idle for an extended period of time.

Proper blade tension reduces the risk of blade breakage and improves cutting performance.

To correctly tension the blade:

1.DISCONNECT BANDSAW FROM POWER!

2.Open the upper wheel door, and raise the blade post and upper blade guide assembly to the highest position.

3.Check the side-to-side deflection of the blade midway between the upper blade guide and the table. The proper amount of deflection should be approximately 38" when moderate pressure is applied (see Figure 23).

Note: The quickest and easiest way to check blade tension is to use the Model H5408 Blade Tensioning Gauge to reach a blade tension of 25,000–30,000 PSI (refer to Page 36)

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.
