One of the things I’m probably best known for is doing hubstack add-on modifications for yo-yo’s that weren’t originally designed to use hubstacks.

You may be wondering, “What the heck is a hubstack?”. Well let me tell you. If you look at a yo-yo from the side and there are no caps blocking you from seeing the actual sides of the yo-yo, there is usually a protrusion in the center generally referred to as a “hub”. It’s there to create a place for the bolt that holds the axle to either thread in or to hold a nut and bolt in place on yo-yo’s that are screwed together. Hubstacked yo-yo’s have a bearing fitted over the hub along with a “stack” that lets you grab the yoyo by the sides without it stopping spinning. Neat huh? This particular development was invented by The YoyoFactory and is an evolution of many ideas, stemming from pointed spikes coming from the hubs, to using bearing equipped spin top tips. The YoyoFactory was the first yo-yo company to mass produce a yo-yo with this type of feature and it really is the best design to date that I’ve seen or used.

So why not just buy a YoyoFactory yo-yo? Well, that really is the ideal way to go. You support the inventor, and the yo-yo’s they make are stellar. The problem is that they are also pretty expensive, costing upwards of $100 and they are not always available since they sell out pretty quickly whenever a run is produced (sometimes, but not always, a limited edition).

The add-on I developed lets you add hubstacks to just about any Duncan yo-yo (and others) for about $30. Cheaper and easier to get your hands on if you want to try it out. And if you don’t like them, you can put your yo-yo back exactly the way you started.

Here’s a picture of the original ones I made from scratch. I’ll post more later on some of the other hubstack mods I’ve done and what you might do with them.

    I recently purchased a AODA yo and would like someone to add dice hubstacks to it because at 63 years old I’m not too steady with a drill. Or does anyone know where I can buy a pair already made ????
    Hope all is well,

      Hi Joe. Which AODA do you have? There are several, apparently knock offs of other yoyo’s.

      you can buy the hubstck kit with bearings at its only $20.00

        That kit allows you to put hubstacks on a yoyo that is hubstack compatible (originally designed to have hubstacks). What I’ve done is add hubstacks to yoyo’s that were not originally designed to have them.
