Hi Rich,

In general, I think you could reuse the core for a lot of purposes 
including a ballast.  In this case, some calculations will be needed 
to make sure the core is big enough and wont saturate.  Before you 
tear down the NST, you might try to melt the tar in the oven and 
maybe fix the problem.
