I'm rehousing a pair of PM100 channels. One of the mid EQ pots broke and needed replacing. With the center taps these have, this was not easy but I found one (this had glue on it).

I tried adding these brass shaft extensions with glue:

But that isn't working, and the knob just crushes the brass fitting - any tips for making this fit better?
