Adjusting blade vertical | Jet Tools J-3410-2 specification

Adjusting blade vertical:

The blade guide bearing seat can rotate as needed to make the blade vertical to the saw table. Follow these instructions.

1.With the saw arm in horizontal position, put a machinists square on the table, and against the blade, as shown. The blade should be square (vertical) to the table. If not...

2.Slightly loosen the socket head cap screw which secures the bearing seat to the bracket bar.

3.Use a wrench to rotate the seat until the blade is vertical. (See Figure 13.)

4.Tighten the socket head cap screw securely.

5.Check the other blade guide for vertical. Adjust, if necessary.

6.After adjusting for vertical, RECHECK THE BLADE FOR PARALLEL. Changes in vertical can easily result in changes in parallelism. See Adjusting blade parallelism.

Test cutting to verify adjustment accuracy

Test cuts can be used to determine whether or not you have adjusted the blade accurately. Use 2 inch bar stock to perform these test cuts, as follows:

1.With the bar stock securely clamped in the vise, make a cut through the bar stock. (See Figure 14.)

2.Mark the top of the bar stock.

3.Move the bar stock about 1/4 inch past the blade so you can begin a second cut.

4.Rotate the bar stock 180 degrees so the mark you made is now at the bottom of the cut.

5.Make a cut through the bar stock.

6.Use a micrometer to measure the thickness variation between the top and bottom of the disc you have cut from the bar stock. Unless things are truly perfectly aligned, there is almost certain to be a certain amount of "wedge" to the shape of the disc you have cut. The saw blade can be considered correctly adjusted when the variation measured is no more than .012 inch across the face of the disc.

If you do not have a 2 inch bar stock available for a test cut, use a larger diameter test work piece rather than a smaller one. The maximum thickness variation on any test piece should be no more than .003 inches, per side, per inch of stock diameter.

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.
