MOT Charging reactor

Hi all,

This is my first post to the list, so hello all!

I am in the process of building my second coil, which will be a DC supplied
system, utilising reactive charging of the tank capacitor.  I have a big
pile of old MOTs, which I am considering some of for the reactor.  What I am
wondering  is, how easy it is to disassemble an MOT core (for the purpose of
inserting an air gap) - I assume the laminations are interleaved, so I
figure even once the welds are removed, its not going to be the easiest task
to separate all the laminations and re-orientate them into solid E and I
sections (the whole thing is covered with resinous gloop).  I would ideally
like 6 inductors - so this could be quite a lot of work!

Any tips from someone who has tried it before would be greatly appreciated.
Otherwise has anyone found another source for such a beast of an inductor!

For reference, I anticipate running 1-2kW through the system from an MOT
based "stiff" DC supply. The switching mechanism will be a TSG incorperating
magnetic + high velocity air quenching - hence the need for some prety
serious HV current limiting!
