PUTTER INSERT INSTALLATION
Whether installing one of our inserts to a putterhead, or any other accessory, there is a best practice to gluing it. To start, the following is required:
1. A good 2-part epoxy and mixing tip. Pictured is Golfworks VB1003, quick set 2900 psi strength club epoxy.
This can be found at: www.golfworks.com
2. Denatured alcohol for cleaning (can be found at Lowes and other DIY stores)
3. 60 grit sanding paper
4. Replacement putter insert (available from us)
Then follow the steps below, including some of the details in the video.
Because our inserts are precision facemilled, the smooth surface of the insert underside is not optimal for glue to stick to. A rougher surface gives the glue a better chance.
While pressing the insert down on to the sandpaper on a hard surface, move the insert in a circular motion for about 30 seconds. When finished, check the insert underside for the desired effect seen below.
Next, place the the side you just sanded against a paper towel wet with denatured alcohol. Clean debris and oils from the insert and do not touch that face again. Epoxy bonds best with clean surfaces.
Clean the pocket of the putterhead the same way with denatured alcohol on the towel.
A q-tip can be used to clean in the corners if desired.
Now test the insert fit in the pocket. Ensure there isn't any debris in the pocket, which could allow the insert to sit an an incorrect height. Our inserts meet the USGA tolerance of +0.006"/-0.004" with respect to the putter face. Inserts fit best in clubs that are in good condition. Significant dents or dings in the club face can affect pocket dimensions and the insert will not fit in the pocket correctly. If the club is sent to us, we will rectify any inaccuracies so the insert sits flush with the face.
Next, remove the cap and plug off the epoxy cartridge. Twist on the mixing tip.
If a glue cartridge gun is not available, use the plunger supplied to start pushing the epoxy through the mixing tip. This method does required a bit of elbow grease, but saves the cost of buying a gun for the epoxy cartridge. Allow the epoxy to run on to your workspace towel so that it has time to mix through the tip, before applying to your club. 2-part epoxy works best when both components are thoroughly combined.
Now apply epoxy to the putterhead pocket. Do not let it puddle as shown at the top of the pocket in the picture below. Keep the tip moving, in the manner of drawing a snake. This is all the epoxy that is required. Now press in your insert and hold with a substantial pressure to that the epoxy flattens out and your insert is square to the face.
After a couple of minutes of pressure, the epoxy has set the insert in position. It's best to allow the epoxy to fully dry 24 hours before sealing the border. As an added measure, the club can be rested on the insert, so the weight of club presses the insert during that drying time.
If possible, allow a 24 hour drying period for the epoxy. Then the next step is sealing the stepped channel.
