STS Slow Motion Video!!!!!!!!!!!!

[michihunter]

And it's your belief that without the string supressors this process is amplified? My take is that even with string supressors the vibration and shock still travel through the string to the parts you have mentioned. Wouldn't the shock be felt with the STS even more at the hand instead of less if what you say is true?

I don't believe so , since the center string is putting a forward thrust at the center of the bow when the string is running wild.

With the STS , shock would be suppressed at the riser and redirected upward towards the limbs which act as shock absorbers more so than a solid riser.

This effect would not work form the limbs back down to the riser r again due to the weakness of the limbs (by comparison)and all things attached to them.

String suppressors without the STS would not be needed in the same way since the rebound would be in a sing song motion and the same shock wave effect wouldn't exist.

Good eye BT! I'll bet your right, but why do so many rave about this product? Maybe it's not so much like a tuning fork as it appears.

Bound to be a new product in the future to off set the effects.

Wonder what it would look like on a real bow, not one of those tinker toys.

Look at the footage and you will see that the shock follows upward and downward from the bumper on the STS.

Watch it a few times and count each unaided pulse as well (where the string is off the bumper of the STS.)

Also...the bumper is only in minimal contact for the whole process of stopping the string.

50% maybe

With the STS absorbing and dispersing the shock, if it wasn't doing what it purports to be doing, would n't there be more shock at the hand? If what you say is that the energy is coming down from the limbs to the riser (with the STS) and yet there is LESS hand shock and vibration, is it your contention that the cam bushings are absorbing a great deal of the energy? If that's so, there would still be a great deal of vibration traveling the limbs wouldn't you think? I have nothing except a loop on my strings, do you feel that with that setup, I'm in danger of ruining cam bushings? And if not, why? With your theory I would think that with nothing at all, no STS, no string supressors, the result would be even worse. Your thoughts?

I am just sittin back on the couch with my popcorn and soda learning how intraciate archery can be. :(Gary here is what it looks like on a "REAL BOW NOT ONE OF THEM TINKER TOYS"

I think because it has not been out there long enough to have the effects known and since bearing wear exsists anyway , I doubt anyone is going to point thier attension to the STS untill alot of repair work starts coming in.

Bearing wear is natural due to the pounding this area takes....I am just saying that the effects of the STS may ramp that effect up.

Nothing at all would be better for the bushings as there would be no off center weight with which to deal with.
The more you put on a string above center , the worse for the attachments.

Just as shooting with you fingers under the nock on a bow that is evenly tillered can eventually break the limb , so goes the bushing.
This same thing is seen where over stressed cables which do not even hold the same weight as the string , if offset a great deal , can quickly tear up the outside bushing and cause cam lean.

Hand shock is due to the forward momentum of the string and the reverb it translates as it comes to stop.

The STS stops this forward action and instead runs it up the string where is is absorbed into the wheel where there is play and then to the axles , where there is play and then down the limb , where there is play and then onto the limb Axel where there is play and then into the limb pockets , where there is play and then into the riser where it ends as it hits a wall.

What little reverb that is left would be taken in by the riser but would be considerably less and of course the rubber bushing on the STS itself would take some of that first shock out as well.

As I said , this is theory and only time will tell but just watch the film and tell me if that isn't the most massive beat down you have ever seen a string subjected to
And where does that thrashing go when it's not in contact with the absorption pad

[michihunter]

You make a good point BT but I disagree with you on the energy travel being that much different. Less hand shock equates to good energy dispersal. If you can remove the energy traveling anywere along the course of the string, it's just that much less being dispersed elsewhere. If the STS absorbs even a small percentage of that energy, then so much the better. Whether it's the STS absorbing it, or the forward limit of the string without the STS, something is going to travel to the cam bushing/bearings. With the STS absorbing a great portion of this energy already, it stands to reason that there is actually LESS energy being dispersed upward. Remember, that video is 1/4 sec. Get the same video taken of a string without the STS and I would bet you'd see a more severe string reaction!!

[BT]

Yes Michi....the string w/o the STS has a whip saw reaction which goes forward and back and therefore keeps the rotation of the cam in play (what little of it there is) and also allows the string to play over a large area which makes up the cam.

When this is eliminated there is no more wheel movement or leveraging over the cam but rather then reverb is translated directly to a solid , non-moving cam.

Take your bow and place it between your knees and push the string forward and pull it back slightly as well.
See how the string uses the area of the cam to play out?.

Now hold the cam firmly and pluck it.

What do you notice?....where did the translation of energy go?

[michihunter]

Into the STS!! But seriously, what you say does not make logical sense BT and is a moot point when trying to answer my question. There is now something absorbing some of that energy in the STS. So the energy is a percentage of what it was originally without it. If you are saying that the forward travel is eliminating that energy and is therefore more efficient, I'd disagree with you. The dispersal woould be longer in elapsed time and therefore more damaging then when the STS absorbs a great amount of that not only on the first strike against it, but all the strikes that follow it. The energy might be more rapidly absorbed with the STS but that does not equate to being a negative. It's the same as a guitar string in an analogy. The longer you allow the string to vibrate, the longer it will make sound. But by pressing down on the string, your finger absorbs the vibration and the sound stops. Without anything on that string, the energy takes much longer to disperse. In no way does that become a negative to the other components because you are dispoersing the energy AWAY from the components that hold the string.
