You mentioned that the laminations were of a very soft metal. This could in=
dicate that they are high permitivity maybe MUmetal rather than standard si=
licon grain oriented steel. If so, don't beat them too much or you will des=
troy the properties of the material. Are the laminations thinner than the u=
sual mains, 60Hz type?=20
Separating them with a solvent or a warm oven first usually works.=20
