Microwave Trannies, how do I rewind them




Hi I have looking at the many posts related to using microwave   
transformers and other transformers and there was someone or more than   
one person who said that you could rewind them.  I have a number of these   
including a 2000va one from a commercial oven and was wondering how one   
goes about rewinding them.  Actually for that matter, how do you take the   
windings off a neon as detailed in the archives?  My problem is that   
these tranformers all have laminated windings consisting of either   
interleaved E shapes or an I and an E shape.  Either way they are bondend   
together tightly making it impossible to remove or rewind any windings.   
 Many times these laminations ar seam/spot welded along a number of sides   
to keep  everything together.
So, do I hacksaw one side of the figure of 8 off? and then rewind the   
core minding out for the sharp edges and hoping that the remaining   
laminations stay together? and then once rewound weld the sawn off piece   
back on?

Maybe in the southern Hemisphere our transformers are made differently   
than those in the USA and europe.

Hoping for a helpful reply :)
