New Spinner Problems

I'm having a hard time getting my tops to boomerang with the tip down and the crown up.

I'm left handed and it seems that my tops always come back with the crown rotated inside (to the right).
I have a short circuit and an electric.  It seems worse with the electric.

Also, I can throw a spinner just fine, it's the boomerang that is messing me up.

I was going to try some V8, but I don't know if I should drink it, or soak the top in it?

Any other ideas?

You should throw tip pointing up.

I like V8.  Give it a try.  Also try having your wrist in different positions, although a good line (as Trip says) is "keep the point/tip straight up."  Sometimes the point has trouble getting all the way around so maybe look into having your tip forward a bit.

Hope you enjoy that V8!!!

The tip is up when I throw.  Which way does the tip rotate when you throw it? (I'm left handed.)

Hi Trip!
Here is something rarely mentionned in boomerang learning videos, and I like to teach that way when I'm teaching: you should better do an "arc" movement (means from when your left hand is on your right crossing your body = end of movement for a spinner) instead of a straight movement, by going first up then left...
Hope i'm clear...

The tip rotates towards the inside for both right and left handed throwers. In other words, from the point of view of the thrower, counterclockwise for right handed and clockwise for left handed.

The rotation is gyroscopic in nature: it's at 90 degrees to the torque (with respect to the center of mass) given by the pull of the string.

You mean when you pull back?

So then I'm over rotating?

If the crown points inside (right for a lefty), I would think so. My guess is that you are rotating your hand on the release. Or you are using a string too short (or thin) for the top.

I think my string is too short.
But I'm getting the KNeff-inator this week so I'm going to start making string. :D

Poor Trip, I'm confused by the answer in this thread, you must be so much :)

Here is my simple take on it. If you have a string length that yeild you a perfectly upright spinner ( on the ground ). You probably could boomerang with the same technique and it would come back to you upright...

At least that always how I setup my string prior to using f*** long strings where throw technique become more adaptative.

Good luck man

But if it's over rotating then the string would be too long right?

No, too short.
A shorter/thinner string will end the wrap lower and have a stronger starting torque.

Oh! That makes so much sense!
