Paper Clip Top or Sakai Top

Bored out of your skull and want an easy 5-10 minute project to entertain you for about an hour?

Well, go grab some bailing wire and a pair of diagonal cutters, or a large <sup>A</sup>paper clip... a pair of needle nose pliers... and a 1" wooden dowel ( or simply - a short length of 1/2" or 3/4" PVC pipe) .

<sup>A</sup> - See note on bottom of post.

<img src="http://i41.tinypic.com/2lu877b.jpg">

1.) Cut an 8" length of bailing wire.

2.) Mark the center.

3.) Place the center mark on the center of a 1" wooden dowel.
(Or, center over a piece of 3/4" PVC pipe)

4.) Bend wire over the dowel/pipe, making sure that the ends are even with one another, making a " U " shape.

5.) Continue bending the ends, another 90 degrees. (in opposite directions, from one another)

6.) Showing completed " loop ".

7.) Eyeball the center and hold firmly with needle-node pliers.

8.) Bend each end at a 90 degree angle.

9.) Shows completed piece.

10.) Bend one end " up " at a 90 degree angle, forming an " L " shape.
Bend one end "down" at a 90 degree angle, forming an " L " shape.

Center picture shows that " h " should match " r" and " a" should form an approx. 52-53 degree angle.

I have found, through experimentation, that you need to "fine-tune" the top. The upper and lower " legs" of the top, need to be inline with one another, as well as paralled to one another. The " a" angle is achieved by bending the circle outwards, as indicated by the purple arrows... The leading edge of the legs may need to be bent in or out, as indicated by the blue arrows.

The center picture was modified off of a site called: <a href="http://www.grand-illusions.com/articles/paper_clip_top/">Grand Illusions - Articles - Paper Clip Top:</a>, and is also a modified version of the instructions on Instructables :<a href="http://www.instructables.com/id/Make-A-nice-and-cheap-paperclip-top/">Make A nice and cheap paperclip top</a>.

I have found, that using a paper clip... sucks! The constant bending (to fine-tune the top) will quickly lead to the upper and lower legs simply breaking off. The bailing wire is much easier to bend and a lot more forgiving to the fine-tuning.

The lower and center highlighted portion of the picture depicts a rounded leg bottom, so that the top will spin easier and faster. - (Kind of a hit-and-miss, with this idea, though).

Hahaha, my dad has one of these from when he was a kid. I remember when Iwas little, I was trying to figure out how to make it work (you needed a piece of string for it to work and I hadn't known that) I ended getting excited because I would jsut roll it across the floor. I though I had figured it out! :lol: :roll:
