That's your problem.  Wax shrinks significantly as it cools, as you'll find 
out if you ever try making candles.

In both situations, the solution is to poke a number of relief holes in the 
top of the wax as it hardens.  This provides a designated space from which 
the wax will shrink away from, instead of finding it's own places where you 
don't want them.

As the wax further hardens, you keep adding more molden wax, to fill the 
voids, until you have it under control, then pour a top layer if you want it 
to look pretty.

I did this on both my 15/150 and a 12/120 (both modified) without any 
problems so far.
