Checking Wheel Coplanarity

1.DISCONNECT BANDSAW FROM POWER!

2.Remove the table assembly from the machine.

3.Make sure the blade is correctly installed and tensioned.

4.Hold a self-made coplanarity gauge (see Figure 50) close to the center of both wheels, making sure that the gauge fully extends across the wheels as shown in Figure 50.

—If the wheels are coplaner (in the same plane), the gauge will evenly touch the top and bottom of both wheels.

—If the wheels are NOT coplanar, place the coplanarity gauge on the upper wheel first, ensuring that it touches both the top and bottom rim. Then adjust the lower wheel to be coplanar with the upper wheel.

Note: The upper wheel of the Model G8146Z can also be adjusted. To do this, refer to the detailed instructions later in this subsection.

Adjusting Lower Wheel

1.Check the coplanarity of the wheels as outlined above, then identify the four wheel adjusting assemblies of the bottom wheel (see Figure 51).

Note: The lower wheel adjusting assemblies have a locking hex bolt threaded into an adjusting sleeve.

2.Use a 17mm wrench to loosen the locking hex bolts.

3.Use a 21mm wrench to loosen or tighten the adjusting sleeves as necessary to bring the lower wheel coplanar with the upper wheel.

Example 1: If the top of the lower wheel leans to far forward (see the top right exam- ple in Figure 50), thread the top two adjusting sleeves out.

Example 2: Alternately, if the lower wheel is parallel to the upper wheel but behind the plane of the upper wheel (see bottom right example in Figure 50), then thread all four adjusting sleeves in.

4.Re-tighten the locking hex bolts to secure the settings of the adjusting sleeves.

5.Re-check the wheels for alignment and repeat the steps above if necessary.

6.Re-check the pulley alignment and V-belt tension (Page 41).

7.Re-install the table and check its alignment with the blade (Page 44).

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.
