shaft choices for sl irons

8 posts in this topic

Hi, I'm new here. I want to build a set of Pinhawk sl irons to seven iron length, but I'm not a regular club maker, so I have some questions. The last thread ichecked had 56 entries, and I still didn't find the info i need. First, since the heads are a six iron design, do I need to add shaft weight to the tips or can I just use heavier shafts? Second, if any of you have built these, what shafts would you recommend? Thanks, guys and gals. Haven't posted much, but I'm an inveterate reader.

Welcome to The Sand Trap! :beer: It's nice to see that you converted from a hawk to a contributor!

Unfortunately, I have no idea how to help you because I have never heard of these clubs and I do not know what you mean by "the heads are six iron design". I am sure that somebody can offer you some help/advise though.

The Pinhawk single length irons have been discussed frequently on this forum dating back to 2010. Haven't found any detailed discussion of shafts for them though. By six iron design I mean the lie and headweight (according to their website) is that of a six iron. Since I want to build them to about 37", I was wondering if I should put 7 gram plugs in the shaft tip or use heavier shafts to get the swingweight right.

A lot would depend on what shafts you intend using in them. Constant weight? Ascending or descending in weight?. Either way, I would think Pinhawk heads are identical in weight through the set, otherwise you would end up with variable flex. Therefore, just use tip weights to get your desired swing weight if using a set of constant weight shafts. If you have a variable weight shaft through the set, you have bigger problems to achieve a constant swing weight and flex. You can't have it both ways I guess, but then again I don't really hold any water with the constant length set theory. If there really were any credence to it, then a lot more people (maybe pros included) would be using them. Gimmick perhaps? If they work for you though, then thats all that matters.

Not sure I buy the concept either, but I always have my original Big Berthas to fall back on. I want everything constant and about a D2 swingweight .I love my seven iron and often find myself opening or hooding the face to avoid clubbing up or down. So, a bagful of my sevens where only the number on the bottom changes seems like something to try. At any rate, my thread isn't about the the theory of sl irons (that's been debated extensively in other threads) but about shaft suggestions.

As I recall, Pinhawk heads are .370" hosel - this is because parallel tip iron shafts can be tip trimmed to get the desired flex regardless of your desired playing length. Shaft suggestion would be relative to what you like in terms of weight and ball flight - bend point depending on how you load and release the shaft. Without any info about your preference or swing style, it's a complete guess. Anyone can guess, as I'm sure you're aware.

I remember back in '70s or '80s a manufacturer did this, Tigershark or something? Neat idea but it didn't catch on for a reason maybe.

Basically, you are building a pinhawk set a half inch shorter than their standard, correct?

I always start with your swingweight. Golfsmith. Golf works etc. have cheap scales. Measure what you are used to. Adjust if you want a little lighter or heavier, and use that to figure out what you want to do with your clubs. If I recall correctly (but this is why I say get a scale), every half inch in shaft length equals about swing weight points - a D-3 becomes a D-0. Roughly about 2 grams of head weight equals one swingweight point. So you are looking at maybe adding 6 grams of weight to each head. However, before you do that and start changing the clubhead dynamics, you might want to see if you can live with the clubs as they are, slightly lighter swingweight. Sure you can put those 6 grams down the shaft. You could also make up some of that weight with lead tape behind on the clubhead. Keep in mind a shorter shaft typically stiffens the flex.

All that makes me ask, why mess with the 6-iron standard? Does the half inch mean that much to you? Considering how far off the beaten path Pinhawks are to begin with, do want to then continue to go off their path? But that is the fun of doing this stuff. If I were in your shoes, though, I might start with a standard 6-iron set up. Then if you want cut the 1/2 inch, sure go ahead, try them. And lastly, if you need to, then add the weight.

I made a set of Pinhawks earlier this year. I made mine 36". I used True Temper Dynamic Gold S300, which is the shaft I normally use. However, since these are tipped 4", they feel a little too stiff. I am going to order another set of heads and put them on regular shafts at 37". Normally regular shafts are too whippy for my faster swing, but I'm trying to reduce my swingspeed for more consistency. I also read a post from one of the makers (I think it was T Witt) recently (was poted a long time ago) that said to use regular shafts for single length. I'll probably go with a mid kickpoint instead of the high kickpoint of the TT DG shafts. Should help increase the trajectory a bit. BTW, I love these irons. The "long" irons take a little getting used to. My GIR has inceased. Even when I miss a green, it is on the fringe. My irons ranged from C7 to D1 before I added any tip weight. I was surprised at the variance of the swingweight since the shaft length is the same and the head weight was supposedly the same. I made them all D1. I made my SW and LW 36" also. I can choke up for shorter shots, but on full shots the longer length is fine.

    • Ball likely in casual water but uncertain
      Interesting. It seems to me that if the ball is in a tree, even when camera follows it, they do not alllw a drop without shaking the ball loose or pulling a Faldo. This happened to Rose this season, they could see a ball with binoculars. They heard it go in the tree but not come out. Had to re tee.
    • Irons, Irons, Irons!
      That's what I'm realizing.  I was at Dick's yesterday and now that all the new models are coming in the old one's are being discounted dramatically.  But I think I'm going to stick with the ping eye 2 irons since everyone seems to be at a consensus that they are fine to be starting out with.  However, I may be in the market for a driver because some of these drivers are so inexpensive right now. I'm considering the callaway xr or x2 because it's like 129 bucks or something.  Right now I play a nike ignite 450cc. I paid 20 bucks for it and it's been great the only thing is, I'm hearing some noise down by the hosel which i suspect isn't the best thing but the face isn't cracked or anything.  It sounds like there is sand in it.  Anyways, I appreciate all the feed back I'm new to site but really like the community of golfers and the fact I can get on here and really express any concerns or ask questions. 
    • My Swing (coop6)
      It pretty much is, I'm not going to debate 5 degrees with you. As I've said repeatedly, Tiger's swing and a standard swing do not require rotation. On this shot he rotated 5 degrees, not much. If you want to play with rotation to closed enjoy. I prefer to keep the club square.

    • No Forearm Rotation - Biggest Swing Flaw?
      Completely bogus. The arms (forearms) rotate in every good golf swing. Here's an old thread that's appropriate for this discussion.   Also, I don't think I've ever really seen a golfer, throughout his backswing, rotate his forearms the opposite way. For short periods of time, maybe a few golfers "counter-rotate," but all end up rotating some. No, there won't be "arguments" over this, or there shouldn't be, because… like many things, this is pretty much a fact. There really doesn't need to be an argument or a discussion. It's a knowable, understandable thing. Hunter, like every other PGA Tour pro, rotates his forearms during the backswing. You're rotating your arms as you do this. It's subtle, but if you just pick the club up straight without rotating, you'll have the shaft resting against the top of your head. Look at where the back of your left hand points. Toward the target at setup, and then rotated to put the club on your right shoulder. Turn to the top when the club is on your face or the top of your head and the club will be leaning out over the target line (it'll be roughly parallel to your bend toward the ball, since it's basically just staying inline with your spine). Bending your right arm rotates your forearms. It pulls everything to the right (you can't bend your right arm straight in front of you without also bending your left arm). Then even more rotation is added after that. I agree that you don't want to be doing a lot of "things" on the downswing, but that's not how physics works. You can do all sorts of things on the backswing and not do them on the downswing. We have students who swing steep to steep, steep to shallow, shallow to steep, shallow to shallow, and all sorts of things. We have students who address the ball with a closed clubface, roll it way open, and then return it wide open, etc. The "equal and opposite" does not mean a delayed reaction - it means that if I push on something it will, right at that very moment, push back. If I fire rocket propulsion downward, the missile or space shuttle or whatever will move upward. You don't fire rockets and then, a week later, a different missile takes off as a "reaction." Furthermore, PGA Tour players have a variety of backswings. Ray Floyd was underneath, Rickie Fowler or Ryan Moore are steep or over the top on the backswing. The golfer who comes closest to the "square" or "no rotation" backswing is a guy who CAN'T really rotate his forearms: Tim Clark. And even Tim rotates some. But notice how far "out over his head" the clubhead is, despite the fact that he's well short of parallel on the backswing. It's so much more than that. I ask people in my lessons how much skill or raw natural talent it takes to set up properly. The correct answer: none. They just have to know how to do it. If golf was as simple as "set up properly and then turn" we'd all be a whole lot better than we are. Golfers can be set up the same and make very, very different backswings, and both can be successful. So Bubba is doing it wrong? And what does that have to do with the swing flaw of "rotating your forearms"? (Is overswinging a big problem? Absolutely. More, IMO, for what it tends to do to the trail elbow and the subsequent inability of the player to get the arms and hands down fast enough. I'll never really argue against overswinging, except when it's made as a blanket statement covering all golfers who go past parallel or something.) Also, you said (though it feels off topic since this is mostly about forearm rotation, n'est-ce pas?) "the more you have to wait for them to come down." That's not really true - you can MAKE them come down faster. Your arms aren't just limp things hanging from your shoulders that get dragged behind your hips and torso rotating. Because, biomechanically, making a swing with no forearm rotation would be ridiculous and resemble the golf swings of precisely no good players, ever. Tim Clark comes closest, and people don't even copy his swing, and if Tim Clark's forearms would rotate as most people's do, even Tim Clark would have a different golf swing. Modeling your golf swing on someone with a disability hardly seems like the prudent choice. My last piece of evidence, right here: This should drive the point home pretty significantly. Spoiler One last thing here. Consider the sagittal plane (in the spoiler above, just so it's not taking up a ton of space) and the back of the left hand (assuming a right-handed golfer). At address, they're parallel - the back of the left hand is parallel to the sagittal plane. Yet at the top of the backswing, what do we see? The sagittal plane (at the point of attachment of the arms, i.e. near the shoulders) is about 90° from where it started. It's inclined at about 35° or so, but otherwise just is still just a plane bisecting the sternum, neck, face, etc. What plane is the back of the left wrist on? Why, it's one that's about 90° to the sagittal plane. I've illustrated this here: In this illustration, I've drawn a little "cube" in the screen on the left. The green face of the cube is parallel to the sagittal plane (the edge of the plane is pointing "at the camera"). The blue side - perpendicular to the green side - is parallel to the back of the left hand. It too is pointing at the camera, but has rotated about 90°. That's why it's parallel to a perpendicular side of the cube. On the right, above, to make the back of Mike's left hand parallel the green face of the cube, he'd have to rotate his arms BACK about 90° to the red line. Now, then, @Golfer2223, you'd set a record as the first human being in history to present an argument as you have done and immediately recognize, given my response and a little thought on your part, that you want to take back your entire argument and completely change your position. In other words, I don't expect that to happen. A small part of me hopes it will some day, but I don't think today is going to be that day. But, realistically, that's what should happen. As I see it, you have no real ground to stand on here. Not biomechanically, not based on simple geometry, nothing. The arms rotate during the backswing in EVERY good player. Even in Tim Clark's backswing (or he'd truly have the club hanging out over his head. I will also say this, @Golfer2223: I appreciate your willingness to help, and to jump in, and to offer your thoughts on things. I hope you can take this rebuttal in the spirit in which it's intended - to help and to discuss. I don't know who you are (you should add more info to your profile), and I'm not responding just to be mean, but to help people learn, think critically, and better understand the golf swing. We encourage debate and discussion here, and that's all my response is to be taken as - more debate and discussion. Do I think I'm right? Yes. And I think I've backed up why. P.S. As someone noted above, often students need to feel like there's no rotation in the backswing. But that doesn't make it accurate.
