I have a couple of water cooled low voltage high current transformers
like these:

They are not the usual kind and have very heavy copper bars and pipes
for windings and cooling.

I want to know how I can delaminate them in an environmentally
conscious fashion. Thanks


I swear you couldn't pour **** out of a boot without asking on
usenet, if
the instructions were written on the bottom...

-you have a large hydraulic press, ****ing learn to USE it.


Seems like it would be easier to pull them out than push them out.
But then he could act like he knows it all and never try to learn
a more cleaver way to do something.

Shear off the winding down the metal core. both, both sides. Pound out
the windings.

We used to use an old electric stove and cook the cores of large motors
and then the copper comes out nicely. Smelly.

Yep, back in the 80's I worked in an electric motor rewind shop. We had
a gas furnace that we would set a bunch of motors in and bake them so
the windings would come out easy.
After they were rewound and varnish dipped, we would bake them again,
in a different oven, not as hot.
