Hey all,

Formvar has the property of curing when heated without the need for exposure
to air. It's used to bond transformer laminations. The transformer is
submerged and a vacuum drawn afterwhich it is heated to cure the formvar
throughout.

Seems Godfrey and I have a common interest in tranny construction. Therefore
our interest in Formvar. But we haven't been able to locate any. Could there
be a substitute? Maybe another method to bond the laminations, coils ... ?
Eliminating transformer buzz can be quite tough for me, especially with
heavy power trannys.
