Restoring an old jointer to its former glory can be a rewarding project, and one of the most important steps is mounting the motor properly. A well-mounted motor will ensure that your jointer operates smoothly and safely. However, if you’re not familiar with the process, it can be a bit daunting. That’s why we’ve put together this guide to help you mount a motor on an old jointer.
Before you begin, it’s important to gather all of the necessary tools and materials. You will need a new motor, a mounting plate, bolts, nuts, washers, and a wrench. You may also need a drill and a screwdriver. Once you have everything you need, you can begin the process of mounting the motor.
The first step is to remove the old motor from the jointer. This is usually done by removing the bolts that hold it in place. Once the old motor is removed, you can install the new motor. To do this, place the motor on the mounting plate and secure it with the bolts. Be sure to use washers between the motor and the mounting plate to prevent the bolts from damaging the motor. Once the motor is secure, you can connect the wires to the motor. Be sure to follow the wiring diagram that came with the motor. Once the wires are connected, you can test the motor by turning it on and off. If the motor runs smoothly, you have successfully mounted it.
Preparing the Jointer
In order to mount a motor on an old jointer, it is important to prepare the jointer in order to ensure a successful and secure installation. Start by cleaning the jointer thoroughly, removing any residual sawdust or debris from the surface using a vacuum cleaner or compressed air. Once the surface is clean, use a measuring tape or ruler to determine the center point of the motor mounting area, which is typically located on the top of the jointer’s frame. It is essential to determine the exact center of the mounting area to ensure the motor will be aligned correctly when installed.
Next, check whether there are any existing holes for mounting the motor. If there are not, you will need to drill holes into the mounting area using a drill bit that is slightly smaller than the bolts you will be using to secure the motor. The holes should be evenly spaced around the center point of the mounting area, and you should follow the manufacturer’s instructions or a jointer installation guide for the appropriate spacing. Once the holes are drilled, use a tap and die set to thread the holes, ensuring the threads are clean and free of any burrs or debris.
After the holes are threaded, insert the mounting bolts into the holes and tighten them securely using a wrench or socket. It is important to ensure that the bolts are tightened to the manufacturer’s specifications to prevent the motor from becoming loose during use. Once the bolts are tightened and the motor is securely mounted, you can proceed with the next steps of the installation process.
Selecting the Appropriate Motor
Power and Speed Requirements
The motor’s power and speed should match the original motor’s specifications. Determine these parameters by referring to the jointer’s nameplate or consulting the manufacturer’s manual. The motor’s power is measured in horsepower (HP), and the speed is typically expressed in revolutions per minute (RPM). Ensure that the selected motor has sufficient power to handle the jointer’s cutting capacity and material thickness. Also, match the motor’s RPM to the optimal speed for the desired cutting results.
Mounting Considerations
The motor’s mounting configuration must be compatible with the jointer’s design. Assess the existing motor mount and determine the necessary dimensions for the new motor’s base and shaft diameter. Consider the following factors when selecting a replacement motor:
– Base Dimensions: Measure the width and length of the jointer’s motor mount to ensure the new motor’s base fits securely.
– Shaft Diameter: The motor’s shaft diameter should match the size of the jointer’s spindle or arbor. Verify the shaft diameter of the original motor or consult the jointer’s technical documentation.
– Shaft Length: The motor’s shaft should extend far enough to reach the spindle or arbor, but it should not be too long as to create an obstruction or hazard.
– Mounting Holes: Ensure that the motor’s mounting holes align with the jointer’s motor mount. Verify the hole spacing and diameter to ensure proper fitment.
Electrical Compatibility
The motor’s electrical specifications must be compatible with the jointer’s power supply. Check the jointer’s electrical requirements and ensure that the selected motor matches the voltage, amperage, and phase specifications. Also, consider the motor’s starting current, which can be higher than its running current. If the starting current exceeds the jointer’s circuit capacity, additional electrical modifications may be necessary.
