Club Shaft and the Bump

Wed, 06/22/2011 - 15:24 -- Don Trahan

A little while ago I did a tip on "The Bump" and how important it is to make good solid contact with the ball at impact. Well, as it happens, that inspired our Director of Club Fitting, Lynn Griffin, to go even a little deeper. He wanted to emphasize the third element I touched on...club length.

In this video Lynn gives an excellent demonstration of "The Bump" and what it actually looks like. Lynn's emphasis is on club length, especially the driver. He shows that if the driver is too long it's physically impossible to "bump" which is key to power and distance in the Surge Swing.

Club length also has to do with your ability to consistently hit the sweet spot with the driver. If the shaft is long, it's harder to control and lack of control means the possibility of more errors. Lynn uses his own "8/10 rule." You have to hit the ball in the sweet spot 8 out of 10 times. If that's not the case, check your club. (Of course my personal rule is 10/10, thank goodness Lynn can take some kidding.)

"The Bump" is power. "The Bump" is distance. Don't swing without it.

Keep it vertical,

The Surge!

I'll give you a call when I'm leaving the house and see if you can get away.

Oh, and I think you're underestimating. The 108 that they're projecting would be ambient temperature, which is in the shade.

I wonder how many people are capable of getting their hands back to the address position at impact without extending toward the ball at least a little and having to pull up or out at least a little?
I have a long way to go to be able to do that with a driver. Much easier of course with irons.
I figure since I just saw DJ do it frame by frame that it's doable but it might be a long hard road. LOL (I know Karl, it's stupid).

Wow,Just got home and watched this video again, Doc, it's a homer. I thought I'd toss that in,seeing how we've been in baseball swing mode the last day or so. The bump is such a subtle move and thanks for demonstrating it so well. Only thing for me that was a downer of sorts is, I missed the clipboards ;)

Well if its anything like it has been the last week or two... cold, windy or wet or a combination of that, with a few nice days in between, and the nice days always come when you are stuck inside with work, Damn Murphy and his law!
Where is she planning to go in Aus and NZ? if its in the north of Australia like the Gold coast  will probably miss the poor weather. the suns UV rays are nasty strong down here, especially in NZ (even in the winter) so if she does get out in the sun remember the sunblock,
I hope she has a great time.

Definition of a lob wedge:   the second most difficult club in the bag to hit well, driver being the first.  A club that most amateurs will hit 3 shots fat, 4 shots thin, 2 chunks, and one good one and say "now that's what I'm talking about".  Take the SW and lay it open if you need to flop.  I see no point in the LW for most guys unless they are going to spend a lot of quality practice time with it and why carry a club that you may need once or twice a round?  GO HYBRID!

Nice to meet you too, Mike and your more than welcome.It was the least I could do seeing how far you drove to meet me. I enjoyed our swing tech session in the driveway at the Golfstop and all of our conversation as a whole.Absolutely enjoyed meeting the face that goes with blog. Take care , my friend and see you next time.

Are you new to the blog?  Am I a medical doctor?  No, I'm a master fitting professional and one of the world top 100 fitters.  I'm also a master teaching professional as well as a certified instructor  for Swing Surgeon and the director of club fitting for Swing Surgeon.

Ok, I'm getting back in and hopefully we can end this back and forth.  You have a lot of good points but you do not have a good understanding of  what is meant by vertical and flat swings as applied in the context of all the conversations on this blog.  A perfectly vertical swing would be as you said, a propeller or as Surge says, a ferris wheel.  A perfectly flat swing would be more like a baseball swing.  So, for the purpose of discussion, a flat swing has the hands behind the ankles and the club outside the shoulder.  In the vertical swing, the club is over the soft part of the shoulder roughly 3 to 4 inches from the ear.  That being said it is physically impossible to swing an extremely long shaft very vertically as it would hit the ground on the way down.  So, by necessity, you have to lower the hands and let the shaft and head be a touch more laid off. 

I'm also curious as to how you were able to use drivers as long as you have described since the LDA rules say a driver can be a maximum of 50" when measured standing on it's toe to the butt end of the grip or 48" when measured conventionally.

I also take exception with your comment about slowing a guys swing down by 15-20 mph.  First, the swing speed is not a measurable item as the equipment is not readily available to do it.  Second, we talk about club head speed.  It is physically impossible to slow one's club head speed down by that much and get more distance unless the individual was using a shaft way to stiff, a head way to low in loft, or creating too much, or too low spin rate resulting in improper trajectory.  I'd have to ask, just which speed are you talking about and how was it measured?  The basic laws of physics would make it impossible since distance is the result of speed of the club head, mass of the ball, mass of the club head, and the coefficient of restitution. So, if you decrease club head speed you reduce ball speed and distance is lost.

 In other words: 

vball = ((velc*(1.67))/(1.0+(ball/mass)))

where :

vball = the velocity of the ballvelc = club
head speed.ball = mass of ballmass = mass of club head

and 1.67 = coefficient of restitution

Your link has nothing to do with the length of the shaft. Your magic shafts have no relevance to whether a vertical swinger can execute a proper vertical swing with a 46" shaft. I don't even think T-Rex could execute a vertical swing with a 46" shaft without sticking it into the ground behind the ball.

Please stop trying to promote your magic shafts on this blog.

Putting was the toughest thing Steve. It got dumb. I will say though that the grip was making me hit the ball at least a club further with every stick in my bag. Now especially with my new clubs I'll have to figure out all over again how far I hit what. I'm thinking about getting a range finder so I can measure each length for every club on the range. meanwhile if I start hitting it over the green that won't be challenge that I would be too upset about.

In answer to your comment below I think the pop tart up to that T finish is super important. As I mentioned to Boog earlier that the wingrite is chabging my game and making all of Surges directions more meaningful with the correct grip and better lag and release up that T finish.

First, my Like is for your having made it to Doc and had your fitting, not for the internet troubles or trying to cut off your pinkie. Looking forward to the report. You missed some fun here on the blog, and you may or may not have seen that DJ shot a 69 and a 62 today. He narrowly missed three putts that would have made it even better (including his 40'10" eagle putt on 15 rolling 41' just over the edge of the hole to stop 2" past for a tap-in birdie--I'm pissed that the Live@ coverage stopped just as he got to the 15th tee).

I recently watched a club fitter measure my clubs.  He set them on the floor then leaned them against a table (he said the club was at 60 degree angle) and then measured FROM THE FLOOR TO THE BUTT OF THE CLUB.

I believe he thinks that a vertical swing is straight up and straight down on the target line.

Funny how EVERYBODY gets all wrapped up about my damaged left leg and what I have to do to compensate for it. Other people are more worried about my leg than I am. Of course I've been having to work around it for a long time. LOL
What I'm more concerned with than anything is someone supposedly passing themselves off as an expert thinks I come over the top. If anything I sometimes drop too much to the inside.

Lynn, terrific explanation. Many folks confuse the "bump" with the turning and full pulling of the torso to a complete finish. The pros pretzel their bodies and have so much torque on their bodies it's no wonder they're in the workout trailer having their backs worked on. As far as the length of clubs, you're right on the money. I'm only 5'6" and I was trying to use a 46" driver. Needless to say, the driver was the most untrusted club in the bag. I cut it down 1 and 1/2" and man, I'm hitting it straight, straight, straight. Now, I don't hesitate to hit the driver. I also cut down my fairway woods 1", and, you guessed it, straight, straight, straight. If I lost any distance I don't care because I now keep it in play. It's amazing how much more fun golf is when you're playing out of the fairway versus the desert or the woods. Thanks for the great video and I hope to see more of you again.

Hey Janet...I know what your saying!...Try this..keep your firm heavy right set up...turn lift and concentrate on extendinding arms at and then thru the ball.  I was holding my angle waaaaay to long which caused to handsy inconsistent  hits. How many times I see Surge lifing up and getting arms extended at the ball....finally clicked for me, haven't hit the ball this good in a long time!!!....So my point is,,,if you work on getting arms extended at impact, the bump just happens!...so one thought for me, took care of a number things...give it whirl!

Egotistical YES. In the SGB YES.In your video I was watching you were firstly talking about the BUMP and the shaft angle of the club in your hand was at least 20 degrees past Don's virtical 'Up The Tree" positionon on more than one occasion. Look at it yourself and you will see what I mean.

Amos,
I think the reason I don't lose much is because I really do get to my left side. I just don't stay there for very long after impact and trying to get back to some balance between my left foot and my right toe, which of course is up, looks a little shaky. It looks much worse than it actually is though and I'm not even aware of it. (Until I watch a video).

For practice, you should find the lowest number you click consistently and work at that point for a few minutes, then try moving up to the next level. Over time, you may find that you can get that next level consistently, but don't try to rip yourself out of your shoes just to step up that level. You're really grooving the release and tempo. The muscles will build and accelerate some over time.

Oh, also you can use it to help groove a good pitching stroke that still accelerates through the ball by setting it lower and taking shortened back swings appropriate for half shots and such. No matter the length of the shot, you want to always remember to be accelerating through the ball, and the SwingRite will help you to get the feel for that with every speed.

One more thing I forgot, my farm work was at a riding stable, so it was mostly shoveling a lot of manure. Now I have a similar job, actually, though the manure is mostly electronic in format. But I'll tell you that having to unload three trailers of hay into a loft ahead of a massive storm will build up strength, stamina, and speed pretty well. I did that a few times. Lugging grain bags up and down hills doesn't hurt, either.

Are you a medical Doctor that loves golf ?  I totally understand what your saying inregards to a shorter driver so you can generate faster clubhead speed and hit the face square. I started my venture in longdrive with a 46" driver ( old school ) and a very easy 6/6 in the grid.
Without giving it up I used to swing: 50-52-55-57" drivers along with my competitors and the longest was 60" driver by a guy out New York.  All my drivers I ever hit never promoted a flat swing because they were balanced and I never had a injury swinging them in competition when it counted.
If I had your longdrive team for a week, you would see the power that I could get out of them. Being in good shape helps a whole lot but I don't mean full of muscle either, I like lanky and cranky with a good foundation ( think about it ). I'am sure you have read everything i"ve said on other blogs about this subject matter. I let a 56yr old guy hit my 50" driver with a regular shaft in it, i slowed his swing down by 15-20 mph and he killed past his normal drive by 25yrds = let the club do the work and your just along for the ride just as long as u keep your head back so it doesn't cross the line. E-mail me back and give me your view.
PS: there is something else I would like to say and  give u my opinion on but please do not get mad at me. Thanks for your response.

Is it better to adjust the toe up or toe down by slight bending of the wrist? I try to keep my wrists straight but tend to stick the toe in the ground and shank the ball sometimes.

If you do not understand the basic tenets of the swing being discussed on this site, perhaps you should do some reading of the manual.
You can find it under the Surge's Shop tab above.

We are all interested in discussing this swing and would be interested in your comments.

The manual is 100+ pages and would be difficult to explain in a simple post.

Hey T.
The lob wedge is kind of a love/hate relationship for me.
Full shots with it are not a consideration at all for me. Any full shot I can hit with my lob wedge I can also hit with my sand wedge.
The dilemma is how important it's going to be on little flops and short sided down hill chips off of tight lies.
There really are some of those shots that I can hit with the lob wedge that can't be hit with a sand wedge. The problem is that those shots take a lot of skill to be worth the risk and some days I have it and some days I don't.
On the days that I don't I'm better off using less risky chips and being satisfied with much longer putts.

I have corrected myself with Ron and said I was sorry and that should be enough and thank you for your concern. I don't blog and one mistake is fine by me and I was asked by one of your active  bloggers for my take on this subject matter and I gave it. I viewed the video and what I saw was not a  VERTICAL  swing and if you did swing  Vertical  you would look like a propeller on a plane without the pitch, now that is vertical.
The idea of swinging a longer shafted driver made for you is to actually slow you down so you can load the shaft with your power then release it at the target--not to speed up your swing and kill your body. A longerdriver is supposed to be the opposite of a shorter driver in swing speed.   Again thank you for your concern.

I have three irons, 5, which is actually a 6-loft at 30*, 6/7 combo iron at 36*, and a 8/9 combo iron at 42*, I then have the three wedges previously mentioned. All shafts are SKF Graphite, I assume they are in the light flex category, since everything is designed for a less than 80mph driver club head speed. I have no idea if weight was added or not to achieve the swing weight of, C5, C6, and C7, respectively for the 3-irons. The wedges are at C8. All are close to a 2560 MOI. All the heads are shown at the Wishon site.

Do you bother reading the answers? Terry has twice given you a link to a video demonstrating the correct way to measure club length, and the correct way to measure your wrist-to-floor length. Simply put, sole the club properly on the ground and measure from the ground up the back of the shaft to the nob at the end of the grip (about 1/8" before the actual end of the grip, given that the butt end of the grip is about 1/8").

Obviously, my reply to you was in the form of sarcastic humor, aimed at your know it all attitude. I have refrained from any further comments in regards to your information, knowledge, and abilities.
 It is quite apparent to me, you do not have significant knowledge of the Swing System being taught and supported on this site and blog, to even discuss it, let alone argue about it. It would be useless for me to even attempt to discuss it with you, until such time as you have at least learned the basic components of said swing system. I will not waste my time or your time trying to educate you in things you have no knowledge about, even though You, still want to foolishly argue about it.
 You fail to realize, you are talking Long Driver’s in a long drive form of competition. We are trying to learn an entire swing system which works the same for every club in the bag and is body friendly to enable longevity of play, NOT, longevity of drives.
Buy the Foundation Manual available through this site for a mere $20.00, study the Swing System, then you may have enough knowledge to at least discuss, what you only think you Now know, but really do not have sufficient knowledge of.
At the present, you have no ammunition to fight this fight with. Get the Manual, become well armed, and then return to the battle. For now you are simply firing blanks that have the sound of foolishness to the majority here.
Good luck in your quest for knowledge. A little, can be a very dangerous thing to possess.
