Use Φ6millimeter stainless steel round bar. Φ6mm round bar is very good feel grip in the hand and good weight feel for playing.

Not use polish round bar.Beads will slip.Mat finish is best.

Outer diameter 245-255millimeter. Many good Chatter Rings are 245mm. I think about 245-250mm good for play childlen..

Need a precision circle.Need strong weld and no dent,no bend,no slide weld finish.

Now,Brass is best.

Good specific gravity material,good low cost, good raw color.

I dont know stainless beads Specific gravity is close to the brass.Try it.

About 5.5mm.

Many good Chatter Ring's beads high 5 to 6mm

Low beads:Slow beads,Jamming beads.
Good high beads:Good speed beads.No Jamming beads.Good bead rotation angle

Rounded shape inside of the beades is best.made by lathe or press.

Trapezoid shape is old shape.

Good balance trapezoid shape:Good speed beads,Good feel beads.No jamming beads.

　　　　　　↓↓↓↓↓↓↓↓↓↓

High trapezoid shape::Bad shape.No grip beads.

Low trapezoid shape:Not good shapeSlow beadsJamming beads.

Rounded edge.

example

7.2 to 7.5gram is basic weight for all player.(Trapezoid shape beads inside)

7.7g:Good feel,little heavy.
7.5g:Good feel
7.2g:Good feel
7.0g:Good feel.little light.Easy speed tricks. Weak sense of the weight of the beads in the playing.

(Rounded beads inside,Rounded edge beads outside -0.35g)

What’s new, trendy or just plain cool

The key to playing with the Gyro-Ring is
to keep the colorful discs in motion.

Gyro-Rings just
keep on spinningJust what are those kids doing? You've seen them on the street, in the supermarket, a friend's home, maybe even your own kid is doing it.

"It" is a clanging Gyro-Ring. More than 1 million sold last year in New Zealand and Australia; 12,000 sold on Maui alone.

Each 91/2-to 11-inch metal ring holds five smaller discs. Once you strike up the smaller discs, then begin turning the ring slowly toward you, the discs perform like gyroscopic tops, spinning around the large ring at up to 1,000 rpms.

The challenge is to keep all the discs spinning while performing tricks.

The colorful beginner model is the Gyro-Ring, $13.95. But there are competition models as well: the Chatter-Ring, Turbo-Ring, the rare Zinger-Ring, $19.95, and Pro-Ring, $21.95. The Pro-Ring comes in a variety of colors: gold, silver, copper, blue and black.

Here's how you do it: Hold the metal ring in either hand. Using the other hand with palm open, strike the discs with a sharp upward or downward movement to get them spinning. Then quickly use both hands to smoothly rotate the large metal ring toward you. The discs should continue to spin as long as you rotate the large ring.

Special Gyro-Ring maneuvers include Roller Coaster, Climb the Ladder and Over the Falls.

Gyro-Rings are distributed in Hawaii by SMP Enterprises Inc., 487-1129. They are available at Kite Fantasy, Liberty House, Ben Franklin Crafts, Wonder Joy Toys at Aloha Marketplace, the Hobby Company and other stores.
