Question about the horizontal width coil

I just bought a 5-pack of plastic adjusters for this since I just bought a JAMMA cabinet that has a monitor with a h. width coil. One of the adjusters was almost the perfect size, but was just a little loose in the allen wrench-style hole in the core. The core was almost all the way out of the coil, so I had to turn at least 25 times before I saw any sort of difference on the screen. After a bit of turning, the tool suddenly could not hold on to the edges of the hole any longer, and now just turns freely within it. I thought that I might have reached the core's maximum, but if I try and turn it the opposite direction, it still does the same thing.

I don't know if this is a torque issue or what... I'm just thinking the turning removed just enough plastic to make it too small. If I added something like masking tape to the sides of the tool, would this make the core likely to crack? It seems like I just need some more surface area to grasp the hole.

what you are experiancing is inductive thermal expansion, quite normal, the ferite core in essence expands at a faster rate than the plastic housing through magnetic resonance, freezing it in place. forcing the core will only lead you to cracking and breaking it
 
Interesting. So are you saying all I need to do is wait for it to cool down, and then try again?
