Last Updated on November 19, 2022 by Robert A. Foreman

How would you like to play tennis without having to spend hours practicing? Well, now you can thank these Tennis Ball Machines. They allow you to practice at home without spending too much time or energy.

Tennis ball machines are an essential piece of practice equipment for every player. They provide a good range of compatibility during the game and improve your skills. If you want to get better, you should invest in good quality tennis ball machines.

You don’t need to go out and purchase expensive tennis ball machines anymore. Here I have told you an easy way to create a tennis ball machine of your own. It is quite a straightforward DIY ball-throwing machine using cost-effective items. 

DIY Tennis Ball Machine

Though there are a lot of cheap tennis ball machines in the market, they are not so durable and effective. So you can make your own tennis ball machine, using affordable equipment. By doing so you can create your own best tennis component. Following the guide below, you can create a tennis ball machine with ease. 

Step 1: You need to create a frame for the machine. It should have an L-shaped configuration. You can use plastic or metal to make the frame. 

Step 2: Attach two right-angle connectors at the back of the frame. It gives a triangle structure and is easy to make the rest. 

Step 3: Now, you have the mainframe. But don’t screw the four corners as you require to install the foot pads. However, you should work with lock nuts as the frame will vibrate strongly while operating. 

Step 4: Install the foot pads in the four corners using screws and complete the frame. Must use rubber foot pads. 

Step 5: Now, let’s ready the friction wheel. Attach the shaft to the wheel module and tighten the screws. 

Step 6: Attach two rivets and a timing belt to the fraction wheel using glue. Leave the headless screw, and I will fix it after the complete assembly. Ready another friction wheel using the same process. 

Step 7: Install the friction wheels to the frame, and you require to use side beams. One friction wheel should install at the bottom of the frame, and the other will be placed a bit higher on the frame. The side beams will be screwed in opposite directions. It looks S-shaped. 

Talking about the distance between two friction wheels, there should be enough space for a tennis ball. In this stage, you also should set the timing belt. The long side of the belt should be on the top side and the shorter one should be on the downside. 

Step 8: Then, start attaching the synchronous belt wheels to the tennis ball launcher motor. Bring out the timing belt through the shaft and attach it to the motor. It would be better to use a CNC drill to assemble the shaft with the motor with ease. You will need two same-sized motors. Prepare another motor in the same process. 

Step 9: You need two motor brackets to attach the motors to the frame. Screw the brackets and install the motor. Meanwhile, cover the timing belt through the synchronous belt wheels. Make sure the belt is as tight as you can. 

Step 10: Since it is a cantilever structure, it can easily be damaged due to vibration. So we will use some bearing on the other end of the shaft of the frame. While adjusting the bearings, make sure the tension of the timing belt is right and close it on the thread slot. 

Step 11: Two beams can be added for more stability to the frame. 

Step 12: Till now, the physical structure is complete. Now, fix the circuit system. First, attach the wire to the motor through welding. You should use 1.5mm 2 sections of wires. Must use a protective tube over the weld’s head to prevent short circuits. 

Step 13: You need two pieces of motor-speed-controls board. It works to modulate the output voltage and control the motor speed by the knobs. These types of boards support up to 12V-30V input voltage. Place the current boards on an acrylic board. 

Step 14: Place the acrylic board with the circuit board on the frame. Use the support of the beams to place it. 

Step 15: Splice a power cord and attach it to the battery. Make sure the cord is connected to both circuit boards and make a secure T-joint. Now, attach it to a power outlet or a battery. 

Now, you are all set, and give a try to your new creation.

FAQ: 

1. How do you make a tennis ball machine?

While making the tennis ball machine, you have to maintain three stages. The main base, friction structure, and the motor part. The whole process is described above in the article. 

2. Is it worth getting a tennis ball machine?

A tennis ball machine is a great equipment for practicing at home. A beginner player can improve skills by practicing through the machine. Though it is not worth it for pro players as the machine serves one type of shot. 

3. How do you make a ball launcher at home?

To make a ball launcher at home, you require some items like a metal frame, wheels, motors, circuit boards, etc. once you collect the equipment, you can create a tennis ball machine following our guide. 

4. Can you use normal tennis balls in a ball machine?

Yes, you can use normal pressureless balls. If you use pressurized balls, they won’t last long in the tennis ball machine. So it would be better to use normal tennis balls.

Final Words

According to many tennis experts, tennis ball machines are the fastest way to improve games. It is true for entry-level players. Because they can practice more and more with the ball machine and make themselves skilled. 

Quality tennis ball machines are expensive. If you don’t want to invest on a larger scale, then try this DIY tennis ball machine. It is a cost-effective tennis ball machine and is best for practice.
