Removal of glue, from jack spring hole

[John Ross]

Hi List,
I have been using the Jack Spring Hole Reamer, with limited success.
The jack springs are held in place by an extremely hard white glue. I still
have a few holes, which resist the reamers action.
Has anyone any suggestions? I feel the problem is to do with the glue. It is
a Young-Chang. Is it a thermal glue?
Thanking you in advance.
Best regards,
