Preschool | Home » » Precision Gyroscope | | | | | | | Description: | | Perform gravity defying tricks with the Tedco Precision Gyroscope! -- This is the most precision designed toy gyroscope on the market. You can perform amazing tricks with this gyroscope, and it's easy! -- To begin, simply hold the frame, and thread the included cord through the gyroscope axle. Wind the cord around the axle while turning it with your thumb and index finger. With a firm grip, pull the cord away from the gyroscope. Hold the frame and push the included T-handle starter strap through the frame and the wheel. Making sure the strap aligns with the gear of the axle, pull the strap away from the gyroscope. -- Tiny ball bearings and near perfect balance keep the gyroscope spinning for several minutes. Durable enough for classroom demonstration. | | | Features: | |

 This Gyro is an excellent classic toyOct 28, 2007
By Rephael A. Foster
"Abletoseetheunseen"
This Gyroscope is the high Quality Toy that used to be purchased at the local mall or the educational store. Now they have become hard to find. This Gyro is durable and comes with the string and the rip cord to start it with. It is an excellent tool for explaining motion and the physics behind the force that balances. I highly recommend this toy.

alternative to string for spinning g'scope very effectiveJul 20, 2010
By En P. Junction
this is a high quality (higher than the archetypal brass and red colored gyroscope) gyroscope. it appears well balanced but best of all it has two methods of spinning it up. First is the traditional string that has to be wound. second, is a plastic t-handle with small notches along the length. the t-handle is fed into the gyrosope with its matching teeth, sort of like enmeshing gears. my 3 year old can get a good enough grip on the t-handle to spin it up whereas he could never use the string. Overall a great toy.

 Right idea but could be betterJan 02, 2008
By Mark Herrschaft
The "old" gyroscopes from my day seem to do better (1960's). I wished it would stay at higher rate of speed to show the effects of the gyroscope better.

Excellent For The priceJun 07, 2011
By Richard H. Wood

I agree with the one reviewer on the need for oiling the bearings as received and suspect that this is true of most toy gyroscopes. Point contact type bearings definitely require lubrication occasionally to give decent life. This unit claims ball bearings but they are molded into the rotor shaft so have been heated up during the plastics molding process. Not good for the original lubrication IMO.
I cannot agree with the reviewer who speaks of gimbals though as this is not a gimballed gyroscope. Amazon does offer gimballed gyroscopes intended for use in engineering and physics teaching but they are considerably more expensive, starting at about $35, with almost all metal construction and going up to about $140 for Amazon's offerings. They are also not suitable for some of the things that this toy gyroscope is good for as typically true gimbal mounted gyroscopes do not include a guard ring around the rotor assembly which all the toy versions have. I believe that the reviewer was referring to the frame and bearings. As noted above a bit of oil helps a lot and will probably extend the life expectancy but there is apparently no adjustment available for rotor end play in the frame.
After oiling it runs well so far for up to a couple of minutes by my timing. That may extend slightly as the bearings break-in or I gain in experience with starting it.
I wish that the documentation of experiments to try shipped with the gyroscope had more than the four examples included. Even a toy like this can be a learning device.
Keep in mind that as a ball bearing supported rotor gyroscope, bearing damage is very likely if it is dropped. The only other ball bearing gyroscopes currently on the market, both a lot more expensive, specifically warn of this hazard in their documentation.

 Lasted One DayJun 04, 2011
By Gurumustuk
"gmustuk"
While my son and I were both excited to have this new toy. It broke in one day. First the krank that you pull wore out (the teeth) so you couldn't spin it as fast....then the plastic circle with the ring got off balance.
Not worth the money.
Pretty disappointing.
