Hubstack Nuts for Duncan
May 16th, 2007 by $eth

Just got this neat e-mail from GReg @ Yo-Yo Guy.com:
They adapt a FHZ and many Duncan yo-yos, as well as other yo-yos that use a 4mm bolt.
The kit comes with two threaded axles of different lengths, two FHZ Stack
nuts and four shims. Since plastic yo-yos are slightly inconstant,
depending on the yo-yo you have, you may need to use one of the shims
under each the nuts to allow the stacks to spin properly.
This kit adapts a FHZ to take YoYoFactory hubstacks. The kit does not come
with stacks, o-rings, or the two size A bearings that the stacks need to
work. Those are available separately, or can be scavenged from an existing
YoYoFactory yo-yo. A perfect way to use the parts you have left when you
upgraded the stacks on your YoYoFactory yo-yo.
(Note: the standard short stack works best, the long stacks are just too
long for this yo-yo).
This kit was manufactured with permission of YoYoFactory. (Thanks to Ben
and Hans)
The kit will be $9.99 as should come out in the next week. You will be
able to find it at YoYoGuy.com

They may take a little modding. The clearances of the stack are not exactly the same. They won’t fit off teh shelf, but it should be easy enough to make them fit.
