I have an idea

So my grandfather was cleaning his house and he found a cheap light up yoyo. He then gave it to me. This made me very happy cause it gave me something to work on. I opened the yoyo to find that is had a weird axle system. it was like a ball bearing yoyo without the bearing. It also had no response. So if figured some stuff out. The part where the two halves me are slightly to large for a c size bearing. So im going to take a dremmel and file that down a bit around the edges. I’m also going to put a friction sticker on it. Now my only problem is weight. Pics of the stock yoyo hopefully coming soon.

thx jrod
