yours for about $10
In the spirit of the DIY Shaft Puller thread ([url="http://www.golfwrx.com/forums/topic/426268-diy-shaft-puller/"]http://www.golfwrx.c...y-shaft-puller/[/url]), I thought I'd post a DIY Spine Finder I made for about $10.



You will need four items.



You will need a 1" PVC coupling.

    can someone post a video of using a bearing to find the spine to make this thread more complete?

    Funny, that's the exact same set up that I have. I went to lowes and was going to get a foot of regular PVC but when looking around saw the pvc/coupling, went back to the bearings isle and they fit perfectly in the ends after **** the caps on.

    About the WD40, I had a lot of experience will ball bearings like that.

    Use WD40 to CLEAN the bearings. WD40 is NOT a lubricant.

    Use a thin viscous lubricant like this one:

    [url="http://www.yoyonation.com/product.php?productid=16220&cat=260&page=1"]http://www.yoyonation.com/product.php?productid=16220&cat=260&page=1[/url]



    Just touch the exposed part of the bearing to the tip, as to get less lube than a drop.

    Then spin the bearing on the end of a pin for a good amount of time, so the bearing can spin freely.

    Dont use dry bearings, as they will basically ruin it over time.

    Just read this this morning and an hour later after a trip to ace hardware I'm done. Great post!



    I didn't even need to epoxy the bearings in as the rubber pieces inside the PVC coupling hold it perfectlygood.gif

    I don't use the bearing method, but I'm wondering why it is debated. It seems like it should be pretty easy to figure it out. Just use the bearing method on four or five shafts, mark where you think the spine is, and then cross-reference it on an accepted machine. Then you can see what the margin of error is, if there is any, and if it's really legit.



    Is there more to it than that?

    It's not so much the bearing method I think, but more how to install the shaft when the "spine planes" are found. Using the bearing method in combination with the laser method you should be able to find the most 'stable' plane. On how to orient the found planes in the head (12/6h or 9/3h) many conflicting opinions exist.

    The debated topic is if spining a shaft yields any performance increase at all.

    You should make a couple of these, Maybe a cleaner way if possible? Or Durable? Anyhow, I would pick one up built for probably $15-20 because I am lazy.

    Most companies already cut a notch in their graphite shafts in which the spine is, I know Miyazaki does this & when was at my club makers using his it came to the exact notch they had cut into the butt. But like SST, don't know if it makes enough difference to matter on the HIGH end shafts out there.

    Yeah, as best as I can figure, the claim that it "helps with consistancy" doesn't make much sense. The club is going to be relatively "consistant" no matter which way you have the spine oriented in the head.

    If the spine does have any kind of affect in the swing, it's going to affect the degree in which the shaft deflects under load. So, even if the spine is not "properly" aligned, it's still going to be perfectly consistant, it's just that it's going to have more or less shaft deflection, that's all.....something that will inevitably be compensated for in your swing.

    I just made one of these with some parts from the Ace hardware. I live in a college town, so the prices could have been better, but Im not complaining. jsut over $20 all day.



    (3) 5/8 inch fasteners at 4.40 each

    (1) pvc coupler was 4.99

    (1) household super oil 2.79



    followed the instruction in the beginning of this post, however, i was able to avoid using any epoxy for the bearings in the pipe. the coupler had some black rubber rings that were almost an inch thick. too small to fit the bearing into, but i just sliced them so they went around the bearing about 95% of the way. Kind of jammed that into the pvc pipe and screwed on the fitting and voila- perfect.



    one last note, the store had bearing that were closer to $20 each which I briefly considered buying (im sure the man in the youtube video above used something that was top of the line). after lubing up the cheapo bearing, they do the job way better than i thought they would. the grease that was in them at the store was pretty stiff, but a little oil really did the trick.



    hope this helps

    In the hardware section where they have all those metal drawers. The best bearing are water pump sealed bearings. No need to lubricate these.

    Not cheap about $6 each.

    Take the coupling with you - the right bearing will just drop in the end snugly without the rubber seal - no adhesive needed.

    Arguing performance gains aside, there's no reason NOT to do it if you are building. Follow it up with a FLO test to compensate for club weighting and offset. All I know is that I've never had anyone dissatisfied with my builds.




    This.



    Definately do the FLO test because the different head will change where you should line up the spine. Do the FLO test with the spine at a 90* angle from where it should be and you'll see why it "might" affect performance. It convinced me.

    Which is exactly why there is a debate.

    There is a difference. Put a spined shaft into a frequency machine and get the number. Then flip it 90* ( not spined) and get the frequency. In many shafts you will see a huge difference. I noticed with Fujikura shafts that they have the most difference from hard side to soft side. Often 12-15 CPM's.



    To the poster that I quoted.



    Build 2 sets. 2 sets of exact same head weights, swing weights, loft and lie, same weight shafts, then spine a set, then completely non-spined side. See your dispersion change, and frequency of the shafts change.

    So, if all shafts in a set of irons is aligned using the soft side against target, dispersion will be good, but if you install them all using the strong side against target line, dispersion will suffer? Why is that?

    What happens if you are using soft side on some, and the strong side on others to make them fit into a flex slope as a set?

    If you are using a tool like this to find a "spine", be sure you're aware of residual bend and a host of other factors before giving the "spine" it finds any real worth. If a shaft with ZERO Spine was put into a device such as this that had a residual bend that even the eye could not freely spot, this "DIY" Finder, will identify that residual bend that is in the shaft as a spine. Is it a spine? no.

    I had some cheap shafts and put one together that was pretty amazing for how long it was. Cheap shafts are a lot of fun when spined and floed. I prefer flo. You can cork a shaft and float it, spine on top.

    I wouldn't bother. Bearing based spine finders have pretty much been shown to be extremely unreliable at finding the shaft spines. If you really feel the need to spine your shafts (which is another can of worms I wont go into in this thread) - use FLO and butt frequency.
