This instructable will teach you how I mod my Bolt yo-yo for an unresponsive style of play that you can't get from most stock yo-yos. The Bolt yo-yo, made by YoYoJam in Florida, plays great out of the package, but it's highly responsive. There's nothing wrong with this type of play; it's great for looping tricks and regenerations, and it's preferred by most beginners.
However, the tricks that have popped up over the last 3 years usually require a yo-yo that can handle a good deal of slack in the string without returning. That's why I mod my yo-yos to return with a "bind", an unresponsive technique I'll discuss later.
For this mod, you will need a yo-yo, a tube of Flowable Silicone Windshield & Glass Sealer, medium grit sandpaper, shims, a plastic tipped syringe and mineral spirits.
I use a Bolt yo-yo (available from this site) for this instructable, but this mod can be done on almost any YoYoJam model that uses o-rings for a response system.
Step 1: A note about "Binds"
Binding is the method used to get a unresponsive yo-yo to return by creating a "bind" with the string. J's glossary defines a bind as "Intentional insertion of extra string segments into the yo-yo gap (usually a wrap around the axle) in order to get an unresponsive yo-yo to return."
It's a really useful technique to know, even if you play with responsive yo-yos.
I highly recommend watching Houdini's "How To Bind 2" to better understand the bind technique.
(Note: I don't recommend "the basic bind" (also known as the lindy loop bind) at all. Instead, study the Backspin Bind and the "Dave" Bind in the video.)
