Replacing blade guide and support components

All component parts are secured with nuts, bolts, washers, or snap rings. To remove and replace any component, first remove the blade according to instruc- tions in Replacing blades. Then remove and replace the faulty component(s).

The guide and support bearings are mounted on eccentric shafts to permit adjustment of the bearing axis. See Figure 11. By loosening the eccentric lock nuts and using a wrench to turn the eccentric, all clearances and positions can be adjusted.

Replacing a blade guide bearing is covered in the section on Replacing guide bearings.

In the case of replacing a single faulty component (such as a single bearing or pair of bearings on an eccentric) you do not necessarily have to adjust all of the other components -- however, their adjustment should be checked when any other adjustment is made.

Before making any adjustments be certain to disconnect the saw from its electrical power source to prevent accidental motor start-ups.

parallel to the stationary jaw, no further parallelism adjustment is required. However, if the blade is at an angle to the jaw, determine which bearing set you are going to move and the direction in which you need to move it. Then proceed to the following steps.

4.Keep the bearing eccentric from moving by putting a wrench on the adjustment tang of the eccentric. (See Figure 12.)

5.Loosen the eccentric lock nut so you can rotate the eccentric using the adjustment tang.

6.Turn the eccentric until you have shifted the bearing assembly to where you want it to move.

7.Tighten the eccentric lock nut.

8.Adjust the bearing on the other side of the blade so the bearing clearance adjustment is correct. YOU MUST PERFORM THIS STEP. The blade is being twisted by the bearing assemblies and a lot of pressure is being exerted by the blade against the bearings. See Adjusting guide bearings.

9.Check the blade for squareness and vertical and re-

adjust as necessary until it is parallel to the clearance slot, square to the vise jaw, vertical to the table, with side guide bearings correctly adjusted.

Adjust blade for parallelism:

1.Use a new blade or a blade in nearly new condition and have it fully tensioned and tracking correctly before making any adjustments.

2.Be sure the stationary vise jaw is at a right angle to the blade. If you are not certain the jaw is correctly adjusted, use the procedure under Establishing a reference angle, to be sure the jaw is correctly set.

3.Lower the saw arm to full horizontal position.

4.Use a machinist's protractor against the stationary vise jaw and check the blade for parallel. If the blade is

J-3410-2, J-3410 specifications

Jet Tools is renowned for its high-quality woodworking and metalworking equipment, and the J-3410 and J-3410-2 drill presses are prime examples of this commitment to excellence. These machines are engineered for precision, durability, and efficiency, appealing to both hobbyists and professional craftsmen.

The J-3410 features a robust 1 HP motor that provides ample power for a variety of drilling applications. This strength enables it to handle a wide range of materials, making it versatile enough for various projects. The machine operates at five different speeds, ranging from 600 to 3,100 RPM, allowing users to select the ideal speed for the specific material and drill bit size they are using. This versatility is crucial for achieving the desired results, whether it’s delicate woodwork or tougher metals.

One of the standout features of the J-3410 is its adjustable table, which can tilt up to 45 degrees, facilitating angled drilling. The table is constructed from heavy-duty cast iron, ensuring stability and reducing vibration, which is vital for precision work. Additionally, this model comes with a built-in laser guide that provides an accurate reference point for drilling, enhancing user efficiency and accuracy.

The J-3410-2 model builds upon the features of the J-3410, offering dual laser guides for even greater precision. These guides help users easily align the drill bit, ensuring that holes are drilled exactly where intended. The dual lasers also enhance visibility, especially in low-light environments. This model also includes a larger work table, allowing for drilling operations on bigger workpieces without compromising stability.

Both models are equipped with a heavy-duty, quick-adjust depth stop. This feature allows for consistency in repetitive drilling tasks, which is essential for users who need to achieve uniform results. They also feature an easy-to-use belt and pulley system for speed changes, ensuring that the transition between different speeds is effortless.

Safety is paramount in the design of the J-3410 and J-3410-2 press. A protective on/off switch prevents accidental start-ups, while the cast iron construction enhances overall stability and reduces the likelihood of accidents during operation.

The Jet Tools J-3410 and J-3410-2 combine power, precision, and safety, making them excellent choices for anyone in need of reliable drilling equipment. Whether for professional use or personal projects, these drill presses stand out in their class, showcasing Jet's commitment to quality and innovation.
