One thing I would like to mention, having repotted my two NSTs in wax (a 
12/60 and a 15/60), is that wax contracts when it cools, and by a 
significant amount.  The way that I compensated for this was to wait until 
the wax had started to set up, maybe a 1/4" solid on the surface, and then I 
poked a series of holes with a small dowel through the top.  This allowed 
for a controlled contraction, air between the top hardened layer and the 
still molten layer, instead of pulling away from the windings internally. 
Of course, make sure you don't do any damage when you're poking the dowel 
down into the guts.

This required another pour (to fill the holes), and I repeated the procedure 
a couple of times until I was satisfied that the shrinkage had been 
compensated for.
