Plastic spacer Lab

Many of Japanese double-handed players use plastic spacers with Yomega Raider yoyos.(such as Yajin and Osaru)

They say that using plastic spacers is the best, since it sleeps long and get good looping response at the same time. Try this only if you are on the level where you can easily do double-handed vertical punching bags and crossover fountains. Also this setting is very difficult to handle. It is almost impossible to make yoyos with plastic spacers that react exactly the same, since they all depend on the conditions of the stars or how hard you tightened up the gaps. I will write down some of the techniques to make plastic spacer raiders.

Caution!!
1.This mod can damage your yoyos. Please do it on your own responsibility.
2.If you fail to mod your yoyos as you wish, there is no other way to help you.
3.Usually, Japanese players break 4 to 5 yoyos before they get what they want. (tightening the yoyos can break the yoyo sometimes). However, you need to hear the yoyos crack.
4.Please do not send me any questions by e-mail. If you need more help, please try to study Japanese first!! (Sorry I'm not a double-handed player. Some of the information is from other Japanese site)

If you were successful making this mod, you are able to doc.
1. Around the worlds more than 10 times! (because it sleeps for a long time) If you are even more successful, you might be able to do 20)
2. Well responding looping tricks. Also you will have a good control of the yoyos.


Requirements for Plastic spacer Mod
1. Get plastic spacers. (you can get then at www.yomega.com)
2. You should be able to do double vertical punching bags or cross-over fountains easily with your normal (raider) yoyos
3. Spend some time to see what's best for you! (you should be able to find out your OWN settings) And be prepared to break some yoyos ;)

If you are not sure about them, if better not try.

1.Get plastic spacers


You only need to get 4 plastic spacers(to make 2 yoyos). You donft have to get any extras because they tend to get used to your hands as you warm them up. Plus there is no ggoodh or gbadh plastic spacers so no need to sort them out.

2.Axle file

Select a short axle (brown?)

By using a short axle, which makes narrower gap, yoyos tend not to break even when you over tightened. Sand about 5mm of both sides of the axle. (if you think your axle was short enough, then you donft have to do it)

3.Put the spacers on your yoyos

Please check star edge sharp one is best.(not sharp one better to not select it)Not New or Old

4.Drop some oil
Use thin oil when you use plastic spacers, such as brain lube and Bandai maintenance oil. (few drops)

If you want to increase the sleeping time (such that to do more around the worlds), reduce the amount of oil you put on.

5.Tighten up your yoyos as if you are to break the yoyos.

(just crank' em up!)

6.The gap between the sides of yoyos with plastic spacer

The top one is a yoyo with plastic spacers. (narrower gap)
The bottom one is a yoyo with metal spacers.(wider gap)

7.Put on your string
Put a single-loop-ended string around the axle.
When you use plastic spacers, its better to make your strings a little shorter than usual, because plastic spacer yoyos with longer strings make the looping go upward. It is easier to control the yoyos with shorter string, however it all depends on the condition of the yoyo.

Slick six is best of select(no need to brake in your new string).When use normalstring .First you puii it by strong power.

8. Sand the spacers (sand on the side that is touching the bearing)

Some people sand their plastic spacers.
If you are unable to make good yoyos, try to sand spacers on the bearing side.(about 2.23mm)
Sand from this side! (see the picture)
Sand this sideAround 2.25mm
Sand from this side! (see the picture)

Some good players do sand, some doesn't. Do whatever that fits you the best!

9. Done!
It might be not as good as you expect. Please try to spend some time to figure out the best way for you. And be ready to break some yoyos! ;)

If you cannot understand cuz of my English problem, or want to know some more details, let me know by writing down to the message board.
If you want to ask questions to some of the Japanese players, please use easy vocabs so that they will understand. (and in detail)
