I don’t know if anyone has come up with this before, but if they have, I haven’t seen it :-P. Some folks like to take the hubstacks off of they hubstackable YYF yoyos from time to time. I admit, I do to sometimes. Nubs were about the only option, other than leaving them bare. So here’s what I came up with: SPACKS! Spikes + stacks = Spacks!
Take the hubstack completely off, and the Spack just slides right over the hub of the yoyo like so:
I machined them so that they stick out a little bit:
Bag O Spacks:
I’ve been working on the idea for a little while, but I’m finally happy with the result. I know YYF has tip tops, but that still uses the bearing. Spacks eliminate the bearing, and thus cut the weight down a little. Basically like using nubs, but you still retain the use of the stacks. Best of both worlds!
On a side note, I did discover that some of the yoyos require a slight bit of ‘massaging’ to get the Spack to stay on good. A spack that is tight on one side of the yoyo might be a little loose on the other side. I assume it has to do with the thickness of the ano. Very simple fix is to just wrap one layer of scotch tape around the stack before sliding the Spack on. In most cases you have to grab the Spack with a pair of pliers, after putting a paper towel over the Spack to keep it from getting scratched up, to pull them off.
Let me know what you think!
