Does boiling bushings that are basically broken in make them any softer? (Indy 92a blues to be specific)
Yes, but there might be a problem. My experience:
If you put them in boiling water for 1min or less, they will be super soft, but only as long as they are hot.
If you put them in for a few minutes, they will be soft forever, but loose every bit of rebound. Pretty much unusable.
So I'd recommend trying it for maybe 1-2 minutes to start. I did it with indy 88a because they sucked anyway, but now they're mush
