ADJUSTING PRESSURE BAR

The pressure bar is located directly behind the cutterhead and rides on the planed surface of the stock, pressing the stock downward on the table. The pressure bar must be parallel to the knives and tangent to the table and set .010" below the cutting circle. To check and adjust the pressure bar, proceed as follows:

1.

 

 

DISCONNECT MACHINE FROM

POWER SOURCE.

2.

Make certain the knives are adjusted properly as

explained in the section “CHECKING, ADJUSTING AND

REPLACING KNIVES.”

3.

Place gage block (B) Fig. 40, on the table surface and

directly under the cutterhead as shown. Using a .010"

feeler gage (C) Fig. 40, placed on top of the gage block,

raise the table until cutterhead knife (D) Fig. 41 touches the

feeler gage when the knife is at its lowest point. DO NOT

MOVE THE TABLE ANY FURTHER UNTIL THE

ADJUSTMENT HAS BEEN COMPLETED.

4.

Move gage block (B) Fig. 41, under pressure bar (D) as

shown. The bottom of pressure bar (D) Fig. 41, should just

touch the top of gage block (B). Check the opposite end

of the pressure bar in the same manner.

5. If an adjustment to the height of the pressure bar is

necessary, loosen lock nut (E) Fig. 42, and turn adjustment

D

screw (F) until the bottom of pressure bar (D) Fig. 41, just

touches top of gage block (B). Repeat the adjustment at

the other end of the pressure bar in the same manner.

ADJUSTING OUTFEED ROLLER

The outfeed roller continues to feed the stock out of the machine after the planing operation has been completed and should be set at .030" below the cutting circle.

To check and adjust the setting of the outfeed roller, proceed as follows:

1. DISCONNECT MACHINE FROM POWER SOURCE.

2.Make certain the knives are adjusted properly as explained in section “CHECKING, ADJUSTING AND

REPLACING KNIVES.”

3.Place gage block (A) Fig. 43, on the table, directly under cutterhead (B). Using a .030" feeler gage (C) placed on top of gage block (A), raise the table until the cutterhead knife just touches feeler gage (A) when the knife is at its lowest point. NOTE: Do not move the table any further until the adjustment is complete.

22-451, 22-450 specifications

Delta 22-450 and Delta 22-451 are notable models within Delta's commitment to high-performance, precision woodworking tools. Designed for both amateur and professional woodworkers, these tools embody an ideal blend of innovation, usability, and durability.

One of the primary features of the Delta 22-450 is its powerful motor, which delivers reliable performance even under heavy workloads. This model is equipped with a 1.5 HP motor that ensures consistent power, allowing users to tackle various materials with ease. The motor is designed to operate quietly while minimizing vibrations, which enhances user comfort and precision during operation.

In contrast, the Delta 22-451 takes this a step further, boasting a slightly more robust 1.75 HP motor. This feature allows for increased cutting capacity and the ability to work with thicker and denser materials without bogging down. Both models come with a high-quality build, featuring cast-iron bases that provide stability and reduce vibration, further contributing to accuracy in cuts.

Another standout characteristic of the Delta 22-450 and 22-451 is their innovative fence system. Both models utilize a patented fence design that is easy to adjust and lock securely in place, providing users with confidence in their cutting precision. This technology makes repetitive cuts simple and accurate, which is invaluable when working on larger projects.

Additionally, safety is a key focus in the design of these tools. Delta has incorporated various safety features, such as blade guards and anti-kickback mechanisms, to protect users during operation. This attention to safety is crucial, especially for those who may be newer to woodworking or those operating in busy environments.

Furthermore, these models also feature a dust collection system that maintains a clean workspace. The integrated ports allow for connection to dust extraction systems, ensuring that the work environment remains clear of debris, which not only keeps the workspace safer but also improves visibility for more accurate work.

In summary, the Delta 22-450 and 22-451 are exceptional tools designed for both professional woodworkers and dedicated hobbyists. With powerful motors, advanced fence systems, robust safety features, and effective dust collection, these models are engineered to enhance the woodworking experience and deliver superior results. Their blend of reliability and innovative technology makes them worthwhile investments for anyone serious about woodworking.
