Yo-Yo and Spin Top Tips
How to
Install a Yo-Yo String A yo-yo
string is one long string, folded in half, and twisted. The end
where the two string meets are tied together to make a loop, eventually
used to make a slip knot for your finger (see 'Slip Knot' below).
The other end, where the string is folded together is where the yo-yo
sits. Untwist the folded end with your fingers in order to separate
the two strings. Untwist it large enough that the yo-yo can be
placed between the strings, so that a single string sits on the axle of
the yo-yo, as shown below. Then simply let the yo-yo string re-twist
together. The string is now installed on the yo-yo.

Double
looped vs. Single loop strings.
The
drawing above shows a single looped string. This is used for
sleeping fixed axle yo-yos and for most ball-bearing models. However,
beginning players benefit greatly by using a non-spinning yo-yo while they
are learning the initial throws and handling of the yo-yo. To
make a fixed axle yo-yo into a non-spinning beginner yo-yo, the string
should be attached with a double, rather than a single, loop around the
axle. To do this, follow the instructions above for installing a
yo-yo string, except that after the yo-yo is placed on the string, cross
the 2 strings, and wrap the string around the axle a second time.
This, in effect, acts like a knot in the bottom of the string, causing the
yo-yo to bounce back up or return more easily to the beginner
player. Once throwing proficiency has been gained, the second loop
came be removed from the axle, returning the yo-yo into a
"spinning" yo-yo.
Slip Knot
- putting a yo-yo string on your finger.
The loop
at the end of every yo-yo is NOT the loop to put your finger in.
This loop is too small or usually too large for your finger, which will
cause the yo-yo to fall off your finger while playing. To make a
slip knot, take some of the straight string that is hanging down from the
tied loop, and put a section of that string into the tied loop. When
you pull that section of string through the other side of the loop, you
have a one-size-fits-all slip knot for your finger. That slip knot
goes on your middle finger (tallest finger) between your first and second
knuckle on your dominant hand (the hand that you write with). DO NOT
put the string at the base of your finger (that is reserved for
rings!). Although it initially feels funny, proper string placement
will ensure tricks can be done most easily.

Atom
Smasher vs. Split the Atom
by Dale
Oliver
As often as I have explained this to a number of people, it
seemingly has
yet to make an impression. They still continue to use the terms
synonymously.
Split the Atom was a Barney Akers trick and it does not utilize the split
bottom entry. The spinner was thrown and then the yo-yo was put on the
string ala brain twister. The string on the left index finger is then
transfered to the right index finger and the trick continues from
there
beginning with inserting the left index finger behind the string hanging
from the yo-yo finger and making multiple forward to back passes under the
yo-yo.
Atom Bomb, aka Atom Smasher begins with the split bottom entry. Then the
left index finger is already in the position to begin the pass unders.
IF YOU HAVE A SPINWIZARD YO-YO
The
unique design of this state-of-the-art, ball-bearing, auto-return yo-yo
makes it the longest spinning and best built on the circumstances, the
yo-yo is practically unbreakable and no parts can be lost. There are only two things that are necessary to be aware of
with this yo-yo.
#1.
In a beginner’s hands, the strings will wear faster than with a
normal yo-yo. This is due to
the string gripping function of the auto-return mechanism.
It is worth it.
#2.
While the yo-yo will not break or lost parts, if it is struck smartly on
the ground at an angle, it is possible for the body of the yo-yo to pop
slightly apart from the side cap. It
does not separate from the inner assembly, but it does render the yo-yo
unworkable. This is easily
corrected if you follow the directions below.
When you disassemble the SpinWizard, be very careful not to lose
any of the parts from inside the body.
Parts will not fall off of the shaft.
Press the yo-yo between your palms (instead
of gripping the yo-yo body) and unscrew the yo-yo.
Check inside the body of the yo-yo under the raised side cap to
make sure that the four steel balls are in the sockets of the four arms
(easily seen). Realign the
pieces in place, put the yo-yo half on a hard surface (even the ground)
FACE DOWN and thumb press around the edges until you hear the cap snapping
back into the body of the yo-yo, or even step on the edges of the yo-yo,
which will snap the two parts together again. Continue the process until the entire cap is flush against
the body of the yo-yo.
The Aluminum
Hollow Point Spin Top
Dale Olivers’ newest
design. The Hollow Point can be thrown with any other Spintastics spin top
inside it so that it spins both tops at once or thrown by itself as an
excellent fixed tip regenerating top.
THIS IS NOT A BEGINNERS TOP! IT IS FOR EXPERIENCED
PLAYERS ONLY! IT IS MADE OF ALUMINUM AND WEIGHS 85 GRAMS. IT CAN BE
DANGEROUS IF EXTREME CARE IS NOT USED ABOUT WHERE AND HOW IT IS THROWN.
NOT RECOMMENDED FOR PLAYERS UNDER 12 YRS.
Throwing instructions.
If thrown as a double top, wind as usual around the cap of the inserted
top and pull string down to the tip of the Hollow Point. Then wind tightly
and smoothly up the body of the top. If you throw the regular top with the
point straight up, tilt the double top so that the point is away from you
slightly above horizontal.
If thrown by itself, start with the end knot at the
first groove up from the tip. Pull the string to the tip and start winding
up the top while holding the end of the string against the top with your
thumb. When the wind gets to the knot, continue winding up and around the
knot. If you use the whole string, you need to tilt the point of the top
toward your body about 45 degrees or if you take one wind of the string
around your fingers you can throw the normal way with the point straight
up. The trapeze can be thrown more or less in the usual manner.
BE CAREFULL WHERE YOU THROW THIS TOP! DO NOT THROW
AROUND PETS, OTHER PEOPLE OR BREAKABLE OBJECTS! BEST
PLACE IS OUTSIDE ON THE GRASS (unless throwing on the ground. A smooth
surface should be used for floor tricks. Concrete will chew up your
point.)
Double Tricks:
1. Double Spinner, on the floor
2. Double Scoop, scooping one top into each hand
3. Two in One, Throw to floor so that tops remain together. (Hint, don’t
pull back.)
4. Double Sky Rocket. Do Two in One, then sky rocket and catch 1 top in
each hand.
5. Double Boomerang, catching one top in each hand.
6. Cork the bottle. After Boomerang, put the plastic top back inside the
Hollow Point.
7. Double Boomerang under the leg.
8. Double Boomerang behind the back.

Dale Oliver's Famous SWEET
SIDE/SOUR SIDE tip
Every Yo-Yo player that has gotten
into string tricks (Brain Twisters, Trapezes, Atom Smashers) knows
what happens when you put the Yo-Yo on the string 'backwards'. It
has a tendency to 'bite' i.e., catch the string and try to wind up.
Some Yo-Yos will tolerate this if you are careful, other Yo-Yos will
immediately 'bite' and freeze up. What does "on the string
backwards" mean? The string is wound around itself (about 7 to
9 times per inch at neutral, depending on the type of string). That
wind is directional (like a one way street). If you have a sensitive
touch, you can feel that the string slides more easily through your
fingers from top to bottom than from bottom to top. The Yo-Yo
spinning at thousands of R.P.M. greatly multiplies that difference.
When the Yo-Yo rides on the 'Sweet Side' of the string, i.e., with
the direction of the string wind, it is smooth sailing. But when it
is put on the string with the spin going against the grain of the
string wind, you have a potential disaster. This function is
actually used in the trick 'Thread the Needle' and 'The Shotgun'.
Many yoers who were trying to learn Brain Twister' from written
directions were continually frustrated by unwittingly putting the
Yo-Yo on the string 'backwards'. What most players don't know is
that the same scenario holds true for the single strand of string
that goes around the axle. This 'single' string is actually 6, 7 or
8 individual threads twisted together to form the string. It is this
unidirectional twist that causes the string to wind around itself
those 7 to 9 times per inch. This unidirectional twist also creates
the some type of 'grain' or 'sweet side' experienced with the
doubled string. The Yo-Yo will actually spin easier and longer in
one direction than the other. I have seen this phenomenon cause
problems in every contest that I have ever witnessed. A contestant
will 'test throw' their Yo-Yo until it sleeps and then try the trick
only to have the Yo-Yo return to the hand without sleeping. They
will take another test throw and the Yo-Yo sleeps easily. Back to
try the trick again and once more the Yo-Yo doesn't sleep. The trick
is to throw a sleeper on the test throw, then take another test
throw to put the Yo-Yo back on the 'sweet side' of the string for
the attempt that counts. When you are on the 'sweet side', the Yo-Yo
not only sleeps easier and longer, but string tricks run smoother
also. I actually use a bi-colored Yo-Yo and set it up so that I know
which color needs to be on the right for the 'sweet side'. Remember,
it's the string not the Yo-Yo so if you use this bi-color method,
when you change a string and test it, you may have to remove the
string and put it back on the other way to match the color you want
to use as a key. It's best to always use the same color as the key
so you don't have to stop and remember each time which is the 'sweet
side'.
For transaxle
players, the sweet side can have an effect too, but in reverse. One
of the biggest problems in using a transaxle yo-yo is getting it up
at times. The sweet side that makes a standard yo-yo work better
will make a transaxle harder to get up....so.....if you are in a
transaxle competition, better to try the trick on the sour side
(particularly on tricks like around the corner) so it will be more
responsive on the return. Also in this vein, most transaxles can be
adjusted to be more responsive by varying the number of wraps around
the axle. The more wraps, the more responsive. You'll also give up
some smoothness at the same time but for some tricks, it can be
worth it.
Dale
Oliver's Secret to Good Loops
The question that I get
most often from advanced players is "How do you do good
consistent repetitive loops?" So see, you're not alone. I
consider the 'simple' inside loop to be in the top five hardest
tricks to master. OK, here we go;
#1. Practice only good loops. The instant they wander, stop and
start over. When you get really good at them, then you can correct
and recover, but until then, you need to train that hand and arm to
do the same right thing over and over until it becomes automatic.
#2. The yo-yo should be tilted about 6% to the outside ( that's just
about like this / ) . (For the left hand, like this \.). This is a
control tilt which keeps the string in contact with the side of the
yo-yo. If the yo-yo is straight up and down, it can roll to one side
or the other too easily. Start your first throw with this tilt and
continue it.
#3, The loop is not a throw, it is a pull. When you start, the yo-yo
should go down toward the floor, then out and then return toward
your hand. Try just letting go of the yo-yo behind you as you bring
your hand forward. This pulls the yo-yo forward. Then just stop your
hand and watch what happens. Depending on the speed of the pull, the
yo-yo should whip past (over) your hand and take off on another
orbit but not quite make it back to your hand the second time. The
only power you need to put into the loop is what is needed to
complete the trip back (not very much at all). This is best
accomplished by doing an inside wrist roll that starts BEFORE the
yo-yo returns to the hand which gently PULLS the yo-yo around the
hand while imparting that little extra power to keep it in orbit.
Precise consistency is the key.
#4. Yo practice, Yo practice, Yo practice.
#5. See # 1.
Good luck, it took me six months.
Dale
Oliver's "Reach for the Moon anyone?"
My nomination for
the five hardest yo-yo tricks to master. Inside loops, Outside
Loops, Hop the Fence, Reach for the Moon, and Punching Bag.
"Hey!", you say. "Everyone can do Loops and Hop
the Fence." Mastery is the key word. Mastery means
you can do about as many as you want to every time you pick up the
yo-yo and you can do them while reciting the Gettysburg Address and
scratching your head with the other hand.
Multiple Reach for the Moon is the only trick I can think of that
I'm afraid to try with a blindfold on. You must follow it and
make corrections. It doesn't follow you. That's why it
is so difficult for most players to do more than 10 of them with two
hands. Dale Myrberg has done over 300 of them. I can't
hold both hands over my head that long. Forget doing Reach for
the Moons that long.
OK...on with the trick. First problem is to get the yo-yo
going the right direction around your hand. Start with this
preliminary trick. Do a Hop the Fence, but when it returns, go
into a reverse or backwards Hop the Fence, then forward again, then
backwards again...hey!...you're doing Reach for the Moon (when it's
over China). Actually, this trick is now known as Planet
Hop. Now for this side of the world. Notice how the yo-yo
passes your hand when you do Hop the Fence. The first pass of
Reach for the Moon is the same direction. You throw the yo-yo
up at a 45 degree angle, but when it comes back, the yo-yo must pass
below your hand (try for about 6" below).
Act as though you are going to do Hop the Fence straight up.
That is, in fact, what you do and when (if) it comes back down, you
loop it back out. you would think that if it has to go up, you
would need to throw it hard...NOT! A very gentle, slow touch
is by far more effective. If correctly thrown at the
beginning, the yo-yo will swing past your hand and go up by itself
without any added power (If sometimes helps in learning the trick to
push your hand straight up the way you want the yo-yo to go as it is
coming past your hand.) and then you add just a bit of power on the
outward bound pass to repeat the trick. I don't use my wrist
at all on the upward part of the trick. In fact, I find it
helpful to hold my cupped fingers together and brace my yo-yo finger
with my thumb just behind the string. That freezes the yo-yo
finger and makes a solid pivot point for the yo-yo to swing
around. Once you actually FEEL the way the yo-yo acts when
this tricks is done correctly, you'll know what the term "in
the groove" really means. It flows almost
effortlessly. But it takes A LOT of practice effort to get
there.
String
Adjustment for Beginning Spinners
String Adjustment for
beginning spinners. Every time a Yo-Yo is thrown, every time a Yo-Yo
is wound by hand, the twist of the string is changed. A beginner
needs to adjust the string for about every three or four times the
Yo-Yo is wound up. If you are having trouble making the Yo-Yo sleep,
drop it. If it won't sleep when dropped, it definitely won't sleep
when thrown. The fastest, easiest and most accurate way for a
beginner to adjust the string (advanced players use string
adjustment tricks like the Flying Saucer) is to remove the string
from the finger, hang on to the Yo-Yo and let go of the string. The
string will quickly adjust itself to neutral. Then wind the string
back into the Yo-Yo BEFORE putting it back on the finger. If it
still won't sleep when dropped, there is a knot in the bottom of the
string around the axle. If it sleeps when dropped but not when
thrown, there is a problem with the throw, not the Yo-Yo. Usually
the hand is moving as the Yo-Yo reaches the end of the string. The
hand must be stopped and relaxed for the Yo-Yo to sleep when it
reaches the end of the string.
