SUPPLEMENT TO PROXY STATEMENT
Dated May 30, 2007

Introduction

     This proxy supplement, dated May 30, 2007, is being provided to the stockholders of Milastar Corporation concurrently with the mailing of our definitive proxy statement dated May 25, 2007, which is first being mailed to our stockholders on or about June 1, 2007. This proxy supplement revises and updates certain information that was provided in the definitive proxy statement and contains additional information for your consideration in voting on the adoption of the merger agreement. Other than as set forth in the proxy supplement, the information contained in the definitive proxy statement remains unchanged.We urge you to carefully read this proxy supplement, together with the definitive proxy statement.

     If have questions about the definitive proxy statement, this proxy supplement or the merger, you should contact Milastar Investor Relations at (952) 929-4774. The definitive proxy statement and this proxy supplement may also be found on the Internet at www.sec.gov. See “Where You Can Find More Information” below or on page 45 of the definitive proxy statement. Capitalized terms not otherwise defined herein shall have the meanings set forth in the definitive proxy statement.

Shares Outstanding as of the Record Date

     As of May 25, 2007, which is the record date for the determination of stockholders entitled to receive notice of and to vote at the special meeting of Milastar stockholders to be held on June 22, 2007, the Company had outstanding 2,888,264 shares of common stock. The definitive proxy statement incorrectly states that the shares of common stock outstanding on the record date as “2,723,264,” which number did not include certain exercises of options to purchase 165,000 shares of common stock by non-executive employees of the Company under the Milastar Corporation Stock Option Plan. The two incorrect references appear (i) in the second paragraph in the section entitled “SPECIAL FACTORS – Purposes and Reasons for the Merger” on page 6 of the definitive proxy statement; and (ii) in the first paragraph in the section entitled “THE SPECIAL MEETING – Record Date; Stockholders Entitled to Vote; Quorum” on page 40 of the definitive proxy statement. In each of the foregoing sections, the correct number of shares of common stock outstanding as of the record date is 2,888,264.

Financing the Merger

     As a result of the change in number of shares outstanding on the record date, as discussed above, there is also a corresponding change to the aggregate merger consideration to be received by Milastar’s stockholders (other than Mr. Stevermer or ESI). Accordingly, the first sentence of the first paragraph in the section entitled “SPECIAL FACTORS – Financing the Merger” on page 26 of the definitive proxy statement should be replaced in its entirety by the following sentence: “The aggregate merger consideration to be received by Milastar’s stockholders (other than Mr. Stevermer or ESI) is expected to be approximately $3,154,278.” No payments are expected to be made to any holder of vested stock options at the effective time of the merger.
