Shotmaker Frequently Asked Questions

Q: Could the Shotmaker insert come loose inside the  golf shaft?

A: Yes. It could. When it happens, you can tighten it yourself if you have the insert tool. If not, have your golf pro tighten it for you. That said, the centrifugal force generated by golf swing should keep the insert in place. During development of the Shotmaker over an extended period of time, the insert has never gotten loose inside Harrison shafts that have perfect dimensional fit to the insert. 

Q: Is the insert intended for wood or iron?

A: The Shotmaker insert can be used for both wood and iron. However, model 83 insert is intended to fit wood shafts only. We plan to introduce inserts for irons in the near future. 

Q: Do I need to clean the inside of the golf shaft?

A: No. There is no need to do that.


Q: What should I do if the red screw comes loose regularly?

A: Please buy Elmer's Washable and Repositionable School Glue Stick from your local office supply store and apply a small amount of glue over thread of the red screw to increase tackiness. That will fix the problem.

Q: How should I clean the insert?

A: Clean it with a wet cloth. If that is not sufficient, use a wet cloth that has been dipped in soapy water.

Q: Could I clean the insert with acetone?

A: The plastic insert lock at the end of the insert will melt on contact with acetone. Acetone will also damage the insert surface paint.


Q: If the expansion lock of the insert came loose with the insert still inside the shaft, how should I remove it?


A: If the black expansion lock that was attached to the butt end of the insert came loose, the followings are procedures that you can use to reinstall it.


1. Remove the red aluminum screw.

2. Attached the detached expansion lock to the tip of the telescoping insert tool. Turn the expansion lock until the insert tool tip is inserted 1/2" deep inside the lock.

3. Apply a very thin layer of 5 minute epoxy (Do not use Crazy glue or any other kind of glue) on the area beside the fan-out region of the expansion lock. Make certain the epoxy does not come in contact with the tool tip as to bond the lock to the tool tip. 

4. Reinsert the expansion lock back into the butt end of the insert with the insert tool attached. Make sure the expansion lock sits firmly inside the butt end of the insert.  

5. Keep the club in an upright position and allow the expansion lock to dry for 20 minutes with the insert tool attached to it. The tool functions as extra weight to push the expansion lock back into the insert.

6. Pull the insert out after 20 minutes.

Q: The insert tool is too short?

A: The combined length of the extended tool and insert is 42 ¾”. Under the USGA and LDA rules, the cut shaft length limit is likely around 48” long. To preserve the tip flex of the shaft, the insert should be placed at least 6” away from tip. The length of the insert tool can reach an insert that goes as deep as the 6” location. Therefore, if the insert tool is too short, this insert is not compatible with the shaft.

Q: If the insert is too soft, will it still work? 

A: The stiffness of the insert needs to fit the swing speed and loading force generated by the golfer. If the insert is much softer than necessary, then its effectiveness will be compromised. The insert needs to be stiff enough to provide the needed stability and to remove shaft deformation.  If it is much softer than required, then it will have limited effectiveness.

Q: What will happen if the external dimension of the insert is much smaller than the internal dimension of the golf shaft?

A: The greater the difference is between the outside dimension of the insert and the shaft bore dimension, the less effective the insert will be. The current model 83 (PWH83) will fit many golf shafts, but not all of them. The best way to find out is to have a local dealer check the dimensional fit between the golf shaft and the insert to see if they are compatibile. There are countless shaft bore dimensions in the market place. We will need your help in building a compatibility list. Share your compatibility experience with us by posting at our forum under the thread of Shotmaker Compatibility List so that we can keep the compatibility list up to date.   

Q: I hear a rattle with the Shotmaker installed.

A: If you hear a rattle, the insert is either not properly locked or it cannot be firmly secured inside the golf shaft. Therefore, it is either loose or incompatible to the golf shaft. If it is loose, just tightens it. If it is incompatible, then you need to try a model other than 83 (PWH83) when they become available. Some experienced dealers have the know-how to modify the insert to improve its dimensional fit. There is a write-up on this subject. This is the link. Click-Here 


Q: How can I cap the grip cap hole without using the grip lock?

A: A ½” black nylon plug is ideal for the job. It fits tightly inside the hole. When the nylon plug is used, it must be glued in place to conform with USGA rules. We suggest that you glue the nylon plug in place with the Gorilla glue because Gorilla glue is a soft glue that permits future removal. The black nylon plugs are available from Harrison in a pack of 10.

Q: What is the difference between the Shotmaker and a grip weight?

A: The Shotmaker is a light weight insert that removes shaft instability, eliminates shaft deformation and reduces impact shock as to improve accuracy up to 40%. Grips weighs are very heavy and are used mainly to slow down swing speed as to yield a steadier swing. The Shotmaker improves accuracy directly, but grip weight does so indirectly. The Shotmaker insert is used mainly for woods and irons, while grip weights are mainly used for putters.

Q: The torque wrench is not working.

A: The torque wrench is feather light weight. The torque wrenches used for weight screws and adjustable clubs are 40 times stronger. When you turn the yellow handle of the insert tool, you should hear clicking sound. If you do, most likely it is working fine.
