After all the bushings are in, I heat all the cauls (aluminum or brass) 
with a heat gun and leave them in for a day. With the heat, I haven't 
noticed anything I could call a difference in fit between 24, or 48+ hours. 
Either way, I still have to chip out the glue at the bottom of the bushing 
of the ones I got too much in.
