Golf is a popular sport that requires precision and accuracy when it comes to putting. The speed of the green can significantly affect a golfer’s performance, and that’s where a stimpmeter comes into play. A stimpmeter is a device used to measure the speed of a green by rolling a ball down a ramp and measuring how far it travels. In this article, we will discuss how to build a stimpmeter.
Materials Required:
- A wooden board (approximately 1 inch thick, 2 feet long, and 4 inches wide)
- A metal ruler (at least 3 feet long)
- A protractor
- A small metal plate
- A ball (preferably a golf ball)
- Tape measure
- Screws
- Screwdriver
- Drill
Steps to Build a Stimpmeter:
Step 1: Cut the Wooden Board Cut the wooden board to a length of 2 feet and a width of 4 inches using a saw. Sand the edges of the board to remove any roughness or splinters.
Step 2: Attach the Metal Ruler Use screws to attach the metal ruler to the top of the wooden board, leaving about 6 inches of the ruler hanging over the edge. The ruler should be centered along the width of the board.
Step 3: Attach the Protractor Using screws, attach the protractor to the bottom of the board, aligning it with the ruler’s centerline. Make sure the protractor is flush against the bottom of the board.
Step 4: Attach the Metal Plate Attach the small metal plate to the top of the board, directly under the ruler’s overhanging end. The plate should be perpendicular to the board’s width and centered along the board’s length.
Step 5: Measure the Distance Using a tape measure, mark the distance of 30 inches from the bottom edge of the wooden board to the top edge of the metal plate.
Step 6: Test the Stimpmeter To test the stimpmeter, place the ball on the metal plate and let it roll down the ramp. Measure how far the ball travels and record the result. Repeat the process several times to get an average.
Calibrating the Stimpmeter:
Step 1: Determine the Slope The first step in calibrating the stimpmeter is to determine the slope of the green where you want to measure the speed. To do this, use a level to find the slope of the green. The slope can be measured in degrees or as a percentage.
Step 2: Calculate the Target Distance Once you know the slope of the green, you can calculate the target distance for the stimpmeter. The target distance is the distance the ball should travel when rolled down the ramp at a specific slope. You can use a formula to calculate the target distance.
Step 3: Adjust the Stimpmeter If the ball travels too far, you need to adjust the stimpmeter by making the ramp steeper. If the ball doesn’t travel far enough, you need to make the ramp less steep. To adjust the stimpmeter, loosen the screws holding the protractor in place and adjust the angle of the ramp.
Step 4: Test the Stimpmeter Once you’ve adjusted the stimpmeter, test it several times to make sure it’s measuring the speed of the green accurately.
Using the Stimpmeter:
Step 1: Choose a Spot on the Green Choose a spot on the green where you want to measure the speed. Make sure the area is flat and doesn’t have any bumps or slopes that could affect the results.
Step 2: Place the Stimpmeter on the Green Place the stimpmeter on the green, with the metal plate facing uphill. Make sure the ramp is aligned with the slope of the green.
Step 3: Roll the Ball Place the ball on the metal plate and let it roll down the ramp. Measure how far the ball travels and record the result. Repeat the process several times to get an average.
Step 4: Interpret the Results The result of the stimpmeter measurement is the distance the ball traveled. The longer the distance, the faster the green. The result can be used to help golfers adjust their putting speed based on the green’s speed.
Materials needed to build a stimpmeter
| Material | Quantity | Purpose | Cost |
|---|---|---|---|
| Aluminum angle bar | 2 | Frame | $20 |
| Stainless steel ruler | 1 | Measuring scale | $10 |

Steps to build a stimpmeter
| Step | Description |
|---|---|
| 1 | Cut two 18-inch pieces of aluminum angle bar |
| 2 | Attach the two pieces to form an L-shaped frame using epoxy glue |
| 3 | Attach a stainless steel ruler to the frame with screws |
| 4 | Attach two ball bearings to the ruler, one at the 1-inch mark and one at the 30-inch mark |
| 5 | Attach two rubber bands to the frame, one at the 15-inch mark and one at the 30-inch mark |
| 6 | Calibrate the stimpmeter by rolling a golf ball down the ruler and adjusting the angle until it stops at the desired distance |
| 7 | Record the distance and repeat the calibration process until the readings are consistent |
| 8 | Test the stimpmeter on a golf course to ensure accuracy |
Common mistakes when building a stimpmeter
| Mistake | Description |
|---|---|
| Uneven surface | If the surface on which the stimpmeter is placed is not level, it can affect the readings |
| Improper calibration | If the stimpmeter is not calibrated properly, it can give inaccurate readings |
| Incorrect placement of rubber bands | The rubber bands need to be placed at the correct distances to ensure accurate readings |
| Poor quality ball bearings | If the ball bearings are of poor quality, they can affect the rolling mechanism and give inaccurate readings |
| Loose ruler attachment | If the ruler is not attached securely to the frame, it can move during the testing process and give inaccurate readings |
How to use a stimpmeter
| Step | Description |
|---|---|
| 1 | Place the stimpmeter on a flat surface |
| 2 | Place a golf ball at the 30-inch mark |
| 3 | Tilt the stimpmeter until the ball rolls down the ruler and comes to a stop |
| 4 | Record the distance the ball traveled |
| 5 | Repeat the process several times and take an average of the readings |
| 6 | Use the average reading as the stimp rating for the green |
Importance of using a stimpmeter
| Importance | Description |
|---|---|
| Consistent course conditions | Using a stimpmeter ensures that the greens on a golf course have consistent speeds, which is important for maintaining course conditions |
| Fair play | A stimpmeter ensures that all golfers are playing under the same conditions, which is important for fair play |
| Improved player performance | Knowing the speed of the greens can help golfers make better decisions when putting and improve their overall performance |
