Hello
I read where Dr.Steven Baumrucker designed a gyroscopic stablizer a few years back, and had a Pat.pending.
I would like to know if they have been MFG.Or dose any one out there have one, or a pic. I find this to be a very interested concept.
----------ZA206 said:Why? You think about building one UNK? Sounds like a good idea if legal for competition (I doubt it though). It'd also probably be illegal for hunting since it'd probably be battery powered.
Sounds like a cool idea though....

I have put some thought and some partial design into the subject a few years back. I was also unable to locate any specific info on past designs. My theory was that you would need two separate gyros. One acting on the X axis, and one acting on the Y axis. My thoughts were to mount one gyro on the end of a stabilizer perpendicular to the tip. Then with a 90 bend another would be mounted straight down. It could be gear driven at the 90 degree axis point, and most likely would benefit from being mounted on a moving bracket that could rotate around the end of the stabilizer. I never built a prototype as it would not be legal for competition in most venues, would be illegal for bowhunting, and could be cost prohibitive to produce and sell. I have no engineering or physics background, and this is just one of many wild ideas I thought would be fun to try. I doubt from this short explanation it makes sense, but thought I would quickly toss my info out.

I thought about this years ago. Although to be a perfect solution would make it more complicated and not worth the gains.
As some one said you would need one in the x and Y directions. Asumming the center of rotation is parrallel to these planes and the Z plane is equivlent to your string that would be correct. The problem I came up with is friction. Now you can have really smooth bearings that spin real nice, but do any of you remember what happens when you spin something such as a top really fast? It begins to rotate
you would need at least 2 gyroscopes in each of the above said axis to rotating in opposite directions to cancel each other out. Even better 3 gyroscopes, whereas the the 2 outside ones move in the same direction and the center either weighs twice as much or move twice as fast. Canceled force will not cause undesired rotation but will give the desired effect. I'll draw something simple up to illustrate this.

Sorry for the delay. I had to take my little guy to swimming lessons and eat dinner.
At any rate, the friction causes the gyroscope to deviate from it's normal center of rotation so a set of gyroscopes turning in opposite directions cancel this effect out and allow the wheels to maintain the desired angular momentum.
Shown below in an ideal situation, 2 blue wheels are rotating clockwise while a red wheel w/ twice the mass rotates counterclockwise. I made them a bigger to illustrate better.

Gyro stabilizer manufactured
There actually is someone making a gyro stabilizer using an electric motor. Not sure if it's legal in competition (FITA bans all electronic devices, NFAA and IBO say nothing about it as far as I can tell). Here's the URL for the gyro stabilizer http://www.maxx300.com/

Here's some info on stabilizers used for cameras and other gear about as heavy as a bow: http://www.ken-lab.com/stabilizers.html They have 2 gyroscopes at right angles to stabilize on 2 axes. I gave this a lot of thought at one time...

Are 2 axes necessary?
I'm not so sure about 2 axes being necessary, as 1 axis for a bow would take care of right-left as well as up-down, the only thing it wouldn't take care of is canting the bow (or rotation about the spinning axis of the disk). I think any class that would allow this type of stabilizer would also allow a bubble level in the sight window, so you know if you're level. I don't know about you, but I never have problems with the rotational stability of my wrist while shooting, but I will on occasion scatter shots up and down. As far as problems being able to change your aim, if you look at the gyros for cameras they specify "pan rates" which basically means that the gyro filters out all high-frequency "noise" or movement, but a slow and steady change of direction should be fine. Plus a pan rate of "20 degrees per second" is pretty fast, that means it would take 4.5 seconds to turn completely sideways and shoot the guy next to you on the line. So it would be fractions of a second to move your aim from the 9 to the 10.

Gyro may be legal for competition
As far as being legal for competition, I've contacted IBO and NFAA. IBO is looking into it, and my local NFAA rep told me that it WOULD be legal for freestyle and freestyle limited classes. I've also contacted my state archery association that hosts the state champ. 300 round, I haven't heard from them yet. Those are pretty much the major target competitions I've competed in, are there others that I'm ignorant about? Anyhow, looks like the door could be open to seeing these in competition soon.
Gyro IBO legal
IBO has declared the Max-X gyro stabilizer http://www.maxx300.com legal for freestyle and freestyle limited classes. They tested it out and everything. So start using those gyros, people!
As a side note, what my NFAA regional director told me before about it being legal in that organization is apparently incorrect. From what I understand they have made no decision one way or the other, and they don't seem in a hurry to make a decision. I think people should start showing up to NFAA events with gyros and force them to make a stand!

no offense guys, but what next?? Seriously, if you have to carry a car battery to the line with you, i feel it is a bit ridiculous. why not just set up a magnetic filed all around your self and have the bow just levitate itself. then all you would have to do was adjust your sight and shoot 60 inside out x's all day long.
