         Re:      Series F 11-1/8% Senior Subordinated Notes due 2007
    

Ladies and Gentlemen:

   
         We are acting as special counsel to Neenah Foundry Company, a Wisconsin
corporation (the "Company") and the Subsidiary Guarantors (together with the
Company, the "Registrants") in connection with the proposed registration by the
Company of up to $87,000,000 in aggregate principal amount of the Company's
Series F 11-1/8% Senior Subordinated Notes due 2007 (the "Exchange Notes"),
pursuant to a Registration Statement on Form S-4 filed with the Securities and
Exchange Commission (the "Commission") on May 6, 1999 under the Securities Act
of 1933, as amended (the "Securities Act") (such Registration Statement, as
amended or supplemented, is hereinafter referred to as the "Registration
Statement"), for the purpose of effecting an exchange offer (the "Exchange
Offer") for the Company's Series E 11-1/8% Senior Subordinated Notes due 2007
(the "Old Notes"). The Exchange Notes are to be issued pursuant to the Indenture
(the "Indenture"), dated as of November 24, 1998, among the Registrants and
United States Trust Company of New York, as Trustee, in exchange for and in
replacement of the Company's outstanding Old Notes, of which $87,000,000 in
aggregate principal amount is outstanding.
    

         In that connection, we have examined originals, or copies certified or
otherwise identified to our satisfaction, of such documents, corporate records
and other instruments as we have deemed necessary for the purposes of this
opinion, including (i) the corporate and organizational documents of each of the
Registrants, (ii) minutes and records of the corporate proceedings of each of
the

Registrants with respect to the issuance of the Exchange Notes, (iii) the
Registration Statement and exhibits thereto and (iv) the Exchange and
Registration Rights Agreement, dated as of November 24, 1998, among the
Registrants, Chase Securities, Inc. and Morgan Stanley & Co. Incorporated.
    

         For purposes of this opinion, we have assumed the authenticity of all
documents submitted to us as originals, the conformity to the originals of all
documents submitted to us as copies and the authenticity of the originals of all
documents submitted to us as copies. We have also assumed the genuineness of the
signatures of persons signing all documents in connection with which this
opinion is rendered, the authority of such persons signing on behalf of the
parties thereto other than the Registrants, and the due authorization, execution
and delivery of all documents by the parties thereto other than the Registrants.
As to any facts material to the opinions expressed herein which we have not
independently established or verified, we have relied upon statements and
representations of officers and other representatives of the Registrants and
others.

         Based upon and subject to the foregoing qualifications, assumptions and
limitations and the further limitations set forth below, we are of the opinion
that:

   
         (1) The Company is a corporation existing and in good standing under
the laws of the state of Wisconsin.
    

         (2) The sale and issuance of the Exchange Notes has been validly
authorized by the Company.

         (3) When the Exchange Notes are issued pursuant to the Exchange 
Offer, the Exchange Notes will constitute valid and binding obligations of 
the Registrants and the Indenture will be enforceable in accordance with its 
terms.

         Our opinions expressed above are subject to the qualifications that we
express no opinion as to the applicability of, compliance with, or effect of (i)
any bankruptcy, insolvency, reorganization, fraudulent transfer, fraudulent
conveyance, moratorium or other similar law affecting the enforcement of
creditors' rights generally, (ii) general principles of equity (regardless of
whether enforcement is considered in a proceeding in equity or at law), (iii)
public policy considerations which may limit the rights of parties to obtain
certain remedies and (iv) except for purposes of the opinion in paragraph 1, any
laws except the laws of the State of New York.
    

         We hereby consent to the filing of this opinion as Exhibit 5.1 to the
Registration Statement. We also consent to the reference to our firm under the
heading "Legal Matters" in the Registration Statement. In giving this consent,
we do not thereby admit that we are in the category of persons whose consent is
required under Section 7 of the Securities Act of the rules and regulations of
the Commission.

         We do not find it necessary for the purposes of this opinion, and
accordingly we do not purport to cover herein, the application of the securities
or "Blue Sky" laws of the various states to the issuance of the Exchange Notes.

         This opinion is limited to the specific issues addressed herein, and no
opinion may be inferred or implied beyond that expressly stated herein. We
assume no obligation to revise or supplement this opinion should the present
laws of the State of New York be changed by legislative action, judicial
decision or otherwise.
