Golf Shaft Flex Chart

Posted by Tyler Sullivan on

How to choose the right golf shaft flex?

Let me say, that every golf shaft company varies in their flex ratings and measurements. This chart is designed to give you a basic guideline for most golf driver shafts.

What can you expect if you choose the wrong golf shaft flex for your unique golf swing?

1. Too stiff - You are playing a golf driver shaft flex that is too stiff. What can you expect? Your trajectory will be low and to the right with a loss in distance potential.

2. Too soft - You are playing a golf driver shaft flex that is too soft, what can you expect? The common assumption is that you will be hitting a large fade or slice because it is too soft. This is incorrect. You can play a softer shaft and be penalized less than playing a shaft that is too stiff. Although it will take more practice on timing and tempo, a golfer can always go down a flex and not hinder there game as much as going up in flex.

For example: My average swing speed is around 118-120 mph and I normally swing Stiff flex. I have played an entire round of golf with an Regular flex in my driver. Although it felt "whippy" and played soft, I was able to find the fairway all day and still have good distance.

With this said, let's find you the right flex right off the bat! I hope this golf flex chart shown above helps you choose the right golf shaft flex.

We offer 2 options in our BombTech Driver seen below.  What flex will you choose?

How to build your own golf driver?

Posted by Tyler Sullivan on

How to build your own golf driver?

Preparation is key! The actual process of building a golf club or golf driver is fairly simple. But, it is the preparation that makes the difference between a golf club head flying off or staying on in any condition.

Step 1: Prepare your club head

This is one of the most important steps in the process. Use a hosel abrading sleeve to rough up the inside of the hosel. Manually abrade the hosel or use a drill bit on medium speed to reduce burrs and scuff up the hosel for better epoxy adhesion.

Step 2: Prep your golf shaft

Measure the inside of your hosel. Once you have determined the actual depth of the hosel, add 3+/- mm to your measurement. Take this measurement and mark this depth on your shaft with tape or a marker. Painters blue tape works extremely well and is easy to remove. Once your hosel depth is marked on your shaft, it is time to "prep" your golf shaft. Sand off enough paint to show the graphite without cutting into the graphite material. Be very careful on this step. Being too aggressive will weaken the integrity of your custom golf driver.

Step 3: Mix your epoxy

There is many types of epoxies on the market. The majority of options work well, but I prefer a 24 hour epoxy as the overall shear strength is typically much higher than a quick curing epoxy. Mix your epoxy rigorously, 30-40 seconds. A recommend option is to add glass shafting beads. The shafting beads will help create a straight and centered installation of the shaft. A small pinch is all that is needed (10% of the mixture).
Add the shafting beads during your mixing process.

Step 4: Install your ferrule

Measure your depth of the hosel with your ferrule held in place. Mark this depth on the shaft. Once you have done this place a small amount of epoxy on the shaft. Hammer your ferrule onto the shaft, to the depth marked. Clean the epoxy off with epoxy solvent wipes, paper towels or a lint free rag.

Step 5: Install your shaft

The most common mistake during this process, is putting too much epoxy into the hosel. Do not pour epoxy into the hosel of your golf driver head. Take your epoxy applicator and place a moderate amount of epoxy inside the hosel without placing too much in the bottom of the hosel. *Putting too much epoxy inside the hosel will cause epoxy to push upside the golf shaft and create a stiff end that will weaken the shaft and cause the driver to break at the hosel. Coat the outside of the golf shaft with a generous amount of epoxy and place inside the hosel with a slight rotation. Clean the epoxy off.

Step 6: Let it dry! If it is a 24 hour epoxy, let your golf driver dry for a minimum of 6 hours depending on the brand.

Step 7: Measure your golf driver shaft

Using a golf club ruler, place your driver at a 45 degree angle as if you were playing the club. Place the golf ruler underneath the sole of the club. At this point, mark you desired length with chalk or painters tape.

Step 8: 

Cut your shaft

Using a hack saw or a chop saw to cut your shaft where marked.

Step 9: 

Almost done..Time to put on your grip

Measure the length of your grip. Mark this length minus a few millimeters with chalk. Place double grip tape on the shaft, coat the double sided tape with grip solvent. Spray or pour additional solvent into the grip and swish around. Place your golf grip onto the golf shaft firmly and insure it is straight. Wipe off excess solvent

Step 10:

Kick your feet up, or head to the range to test your new custom golf driver.

What is the face angle of a golf driver?

Posted by Tyler Sullivan on

What is the face angle of a golf driver? And what does it mean for your game?

Golf drivers from 2 years ago and before were manufactured with closed face angles from ranging from 0.5 - 2 degrees. A closed golf driver face was thought to help control a slice.

But a closed face angle merely points your club left of target and doesn't solve the problem of hitting a slice. A very closed club face of 1 degree or greater can impact ability to work the ball. The ability to work the ball is hugely important when trying to shape different drives and hit tough shot patterns.

So what do the pros hit? The majority of golf pros on tour play a neutral or open face angle. This allows them to work the ball in all directions with ease. As a closed club face would hurt there ability to work the ball.

What is the right Face Angle for your game? The majority of golfers should be playing a neutral or 0.5 degree closed face. If you are looking to cure a slice through a closed face angle, it will only help but not cure it. And the degrees closed will have to be very strong to truly make any impact.

If you are thinking about face angle and what it means, unless you are playing a fully offset golf driver. I highly recommend playing a neutral club face. You will hit where you are aiming and have the ability to work it like the pros.

University of Vermont Photo Shoot

Posted by Tyler Sullivan on

It is not often that you are asked to do a photo shoot. When Josh Brown a writer and photographer for the University of Vermont called to take photos at the golf driving range. I was more than excited to say yes. Here are just a couple photos of myself and the UVM Engineering students that designed the Grenade golf driver.

Thanks to Josh Brown, to the students and the University of Vermont!

Warm Up For Longer Drives

Posted by Tyler Sullivan on

Warm Up For Longer Drives

Like any sport, proper warm up is key to playing your best. Golf is no different! A full and proper warm up will help you hit longer drives…This I guarantee.

Today made me realize how important this really is. I was in a rush today, but wanted to go hit some balls. So I ran over to a local indoor simulator to take some swings. I had no time to properly warm up. I went right in and starting swinging driver, which I never would normally do.

My club head speeds were low to start off, but never got to the normal range for my swing. My club speed with a proper warm up ranges from 125mph-131mph. Today with no warm up the fastest I could get to was 122mph, which was 3mph-8mph less than average.

I understand, many of us don’t have enough time to practice and warm up. But, taking 10 minutes will help you hit longer drives without lifting a single weight or going to the gym.

This is what I call the 0-300 warm up. Go from 0 to 300 yards or as close as you can. Rest 2-3 minutes between sets.

1. 10 swings of Sand Wedge at 40% power – REST 30 seconds between swings! This is extremely important to training your muscles for speed.

2. 10 swings of 8 Iron at 50% power.

3. 10 swings of 6 Iron at 60% power.

5. 2 swings of 3 wood at 80% power.

6. 5 swings of driver at 80% power.

7. 3 swings of driver at 90% power. Rest for 3 minutes

8. 3 swings of driver at 100% power. Rest full 1 minute between swings.

9. 10 swings of driver at 100% power. Rest 2 minutes between swings.

10. 5 swings of driver at 100% power.

DONE. Go play golf.

This is a simple warm up that can help you still go through your bag and get properly warmed up for longer drives off the tee.

This may seem very similar to a basic warm up, but the proper amount of rest between swing sets will help you get loose properly.

Give this warm up routine a try next time you are looking to bomb your drives longer and make your friends jealous!
