quick YYF Short Circuit mod


(DOGS) #1

The YYF Short Circuit is a great little top. It’s remarkably stable for its light weight, but I wanted to play around with it a little to see what I could eek out of it. My two goals were to increase the apparent weight a small amount and improve stability.

Here it is in the start. I hit the logos on the body with brake cleaner to remove them.

I found that I could slip o-rings onto the underside of the crown very effectively. I initially tried two rings but found one to be optimal.

I’m going to remove the bottom of the string pod feature to remove some center weight. Here I’m indicating where the center of my drill hole is going to be by using the good ol’ pokey mcpokerson.

Here’s my pilot hole.

This’ll work. Trust me.

H-here we go!

So far so good…

Almost done. I’m going to cut that off with a blade.

Sand it up, slap on an o-ring, all done!

Plug the crown back in to the rest of the top and it’s ready to play. The string capsule will still function the same exact way, and only results in a minor visual difference compared to an original Short Circuit.

Although this modification is very subtle, it does change how the top performs a good deal. While the original felt a little light and fast in play, this mod adds just a tiny amount of weight, but a considerable improvement in stability for those tricks you need a little more power for.

Cool!

I like your box of o-rings!


#3

I think that’s called a “box o’ o-rings”.

This is great! I also like to remove the string bucket (I have a lathe so it is a little easier). I can’t say that I feel a noticeable difference afterward removing the bucket alone but I sure do like being able to dump all the string in there quickly, and having access inside for fine tuning. I have not tried your o-ring idea yet but it sure seems like a worthwhile mod to me.

Another thing I have used to add weight in a small top is to add silicone in the bottom third. Just dump it in there, level it and let it cure. This mod may not work with this top however; I heard even adding the weight of a metal tip confuses the spin axis (totally not the correct scientific term but yeah) and the thing just spins wild.

Maybe try flowing the silicone into that recess where D O G S put the o-ring?

There was a seam on the hip of the top that was bugging me, so I went and sanded it smooth. Finished it with 400 grit to leave a light satin.

Plays identical, but loooook how smoooooooooooth

Mmmmm silky. I love that finish on tops, I like to sand the glossy finish of the bottom half so my fingers don’t grab when I scoop. Kinda like what anno does for finger grinds compared to polished chrome. It’s funny, I believe the Bearing King’s orange peel surface on the bottom half was designed to “grab the string”… well less surface area is grabbing the string, so NO, and unless it has peaks to hook into the string, which would hurt… yyeeNO. BUT! it makes a great surface for fingers to scoop. Only the clammiest of hands can’t scoop a Bearing King.

Two more for CarlGel and I. Same treatment as before, more or less.


#9

Oh so sweet

Is that a Giraffe / Grizzly / Rhino 3-way?

Tops are awesome too


#10

It’s the Diverse Animals logo.

They look awesome!

btw I’m doing this


#12

Very nice!

The O-ring addition could perhaps fix the metal tip instability that Neff mentioned. Our theory is that changing the plastic tip for the metal tip makes the top behave more like a ball by equating the transverse and longitudinal moments. This would make them different again. I have to try it.

Thanks for posting it!

I was able to try this recently. It doesn’t fix it at all! I would really like a Short Circuit with a more durable point - the search continues!
