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.
