Porter-Cable Jig Saw manual

•The objective is to make the parts fit closely together. Maximize the gluing surface by making the tenon as long as possible (approximately 1/2 the width of the stile or longer, if using narrow stock). Balance the joint by using the same amount of wood in the tenon as in the combined thickness of the mortise walls (Fig. 26). If one piece of wood is larger than the other, make the tenon as thick as possible (Fig. 27).

•Remember to figure the kerf of the saw blade when setting up for the cut.

•Cut all mortises first. Make the mortise 1/16" deeper than the length of the tenon to allow for glue.

You can use several different methods to cut a mortise and tenon. The following information illustrates one of the easiest and safest methods and utilizes cheek cuts first, then shoulder cuts. Use a base stop (F) Fig. 28 that is the same thickness as the base plate (G) of the tenoning jig (H) and spacer block (K) that is the combined thickness of the tenon and the saw blade, to make the cutting more efficient. This method eliminates possible errors caused by thickness variations in the workpiece, and avoids trapping cut-off pieces between the saw blade and vertical support plate (N).

NOTE: Perform your practice cuts on scrap material before cutting good wood.

Use a slow feed rate to help prevent the tenoning jig from lifting during a cut.

1.Clamp a base stop (F) Fig. 28 (the same thickness as the base plate (G) of the tenoning jig (H)) on the front of the saw table. This will allow tenoning jig to pass over the base stop (F).

2.Make a spacer block of wood (K) Fig. 28, equal to the thickness of the tenon plus the thickness of the saw blade.

3.With the tenoning jig (H) Fig. 28 located at the front of saw table and over the base stop (F), load the spacer block (K) and the workpiece (L). Securely clamp both in place with the clamp handle (M). Make certain that both pieces of wood are against the vertical support plate

(N)and the backup board (P).

4.Gently push the tenoning jig (H) Fig. 28 toward the saw blade until workpiece is near the saw blade. Adjust the tenoning jig (H) and the saw blade to make the first cheek cut. Return the tenoning jig (H) to the front of saw table.

5.Connect the saw to the power source.

Keep your hands on the jig handles when performing cuts.

6.Turn the saw “ON” and perform the first structural cheek cut (Fig. 29). Feed the tenoning jig toward the saw blade at a slow feed rate until the saw blade has exited the back of the workpiece. Turn the tool off and allow the blade to come to a complete stop, then slowly pull the tenoning jig back to the position shown in Fig. 28.

Jig Saw specifications

The Porter-Cable Jig Saw is a versatile power tool renowned for its precision and reliability, making it an essential addition to any woodworking enthusiast's or professional tradesperson's toolkit. Known for its cutting accuracy and ease of use, this jig saw boasts a variety of features that cater to diverse cutting applications, from intricate curved cuts to straight lines.

One of the standout features of the Porter-Cable Jig Saw is its powerful motor, which typically ranges from 5 to 6 amps, providing the necessary strength to tackle tough materials, including hardwoods and metals. The variable speed control allows users to adjust the cutting speed according to the material being worked on, with speeds reaching up to 3,200 strokes per minute. This adaptability ensures clean cuts and reduced splintering, especially when working on delicate projects.

The jig saw's stroke length is also crucial; the Porter-Cable models typically feature a stroke length of 3/4 inches, allowing for efficient cutting through various thicknesses. Additionally, the tool’s onboard bevel capacity allows for angled cuts, expanding its versatility for more complex designs and projects.

A valuable technology present in many Porter-Cable Jig Saw models is the keyless blade change system, which enables rapid blade swaps without the need for additional tools. This feature saves time, ensuring that users can switch between blades for different applications seamlessly. The tool's compatibility with a wide range of jig saw blades ensures versatility, as users can choose from various materials and tooth configurations based on their specific cutting needs.

Furthermore, the Porter-Cable Jig Saw often incorporates an integrated dust blower, which keeps the cutting line clear of debris, ensuring better visibility and improved accuracy. Some models even come equipped with an integrated LED light, illuminating the work area for enhanced precision during cuts in dimly lit environments.

The ergonomic design of the Porter-Cable Jig Saw is another beneficial aspect. It often features a comfortable grip and a lightweight construction, allowing for extended use without causing fatigue. The rubberized handle improves control and reduces vibrations, enhancing overall user experience.

In summary, the Porter-Cable Jig Saw stands out for its combination of power, versatility, and user-friendly features, making it a reliable choice for anyone looking to achieve precise cuts in various materials. Its thoughtful design and advanced technologies contribute to its reputation as a go-to tool for carpenters, hobbyists, and DIYers alike.
