How do you customize the Beyblade?

I've thought of this myself a lot and here is one way to make it:

1. you need a base a screw will do
2. then put the screw with a molly blot with a plastic base on it to help the top stay up when spinning
3. now you need a metal cone to make the base
4. weld the molly blot to the bottom of the cone on the inside and outside(make sure to make the weld marks equal on the opposite side so that the top will not wobble or fall over so easy when spinning)

I haven't got much farther than that in the idea but when i build my own i'll share it, but some tips make sure the top doesn't weight too little it's harder to get it spinning in one try when it weights too little also make sure it is parallel so it can say spinning.
