I'd agree with Joe on this one.  A much better idea would be to use thick or 
medium viscosity CA glue:  Remove the pin, apply some CA glue in the hole and 
a little on the pin itself and drive it back in.  It will go in easily and 
for the first minute or two, it will turn very easily as if it had been 
greased.  But within a few minutes, it will begin to seize up and you will be 
able to tune normally.  The glue will serve to fill gaps that may be in the 
pinblock.  Rather than splitting it further apart, the glue may have the 
effect of repairing the weakness.

The use of shims is an outdated idea that is of questionable benefit for the 
very reason Joe cited.  Before CA glues were available, Epoxies were used but 
the CA glue works even better and faster.
