                    the Securities and Exchange Commission.  Certain
                    information and footnote disclosures normally included
                    in financial statements prepared in accordance with
                    generally accepted accounting principles have been
                    condensed or omitted pursuant to such rules and
                    regulations, although the company believes that the
                    disclosures are adequate to make the information
                    presented not misleading.  It is suggested that these
                    condensed financial statements be read in conjunction
                    with the consolidated financial statements and the
                    notes thereto included in the company's latest annual
                    report on Form 10-K.

                    Statements for the three month and nine month periods
                    ended September 30, 1999 and September 30, 1998
                    reflect, in the opinion of the company, all adjustments
                    (consisting only of normal recurring accruals)
                    necessary to present fairly the results of these
                    periods.  Results for interim periods are not
                    necessarily indicative of results for a full year.

          NOTE 2    Acquisitions

                    On February 17, 1999, the company acquired all of the
                    outstanding shares of Metal-Lab of Wisconsin, Inc.
                    ("Metal-Lab"), located in Sturtevant, Wisconsin, for
                    $9.9 million.  Metal-Lab primarily serves the tool and
                    die industry.  The cost of the acquisition has been
                    allocated to the assets and liabilities based on their
                    estimated fair market value.  Goodwill is amortized
                    using the straight line method over 30 years. The
                    acquisition was funded with borrowings under the
                    revolving credit agreement.

          NOTE 3    Debt

                    In February 1999, the company's revolving credit
                    facility with its banks was amended to increase the
                    borrowing capacity from $45 million to $70 million.
                    Additionally, the amendment extended the maturity date
                    of the agreement relating to the facility to December
                    2001 and adjusted certain loan covenants.

          NOTE 4    Material Changes

                    No material changes have occurred with respect to the
                    company's contingent liabilities outlined in the
                    company's 1998 Form 10-K through the date of this
                    report.

          ITEM 2.   MANAGEMENT'S DISCUSSION AND ANALYSIS

            OF FINANCIAL CONDITION:

            At September 30, 1999, the Company's total debt was $41.6
            million, an increase of $6.8 million from $34.8 million
            outstanding at December 31, 1998.  The Company's total debt to
            capitalization ratio was 40% at the end of the third quarter
            of 1999 as compared to 38% at the end of 1998. During the
            third quarter of 1999, total debt was reduced by $700,000.

            The level of debt increased as of September 30, 1999 in
            comparison to the level at the end of 1998 primarily as a
            result of the acquisition of Metal-Lab of Wisconsin, Inc. on
            February 17, 1999 for a purchase price, net of cash received,
            of $9.9 million.  This transaction was funded with additional
            borrowings under the Company's revolving credit agreement. The
            cash effect of this purchase was offset to a degree by cash
            generated from the sale of the last discontinued Precision
            Products operation - Arrow Acme Company - during the first
            quarter of 1999, which was used to repay debt.

            In February 1999, the Company amended its revolving credit
            facility to increase the total borrowing capacity from $45
            million to $70 million, extend the maturity date of the
            agreement relating to the facility to December 2001 and to
            adjust certain loan covenants.  At September 30, 1999, the
            Company had $37 million of available capacity under the
            amended revolving credit facility.

            Capital expenditures for the first nine months of 1999 were
            $8.3 million as compared to $7.7 million in the corresponding
            period of 1998.  The spending in the first nine months of 1999
            related primarily to the addition of furnace capacity and
            ancillary equipment at certain of the Company's facilities.

            On July 22, 1999, the Board of Directors declared a cash
            dividend of $.08 on each share of the Company's common stock,
            payable on September 1, 1999.  The total cash dividends paid
            on the latter date were $473,000.  This compared to a dividend
            payout of $.08 per share of common stock, or $470,000 in the
            same quarter of 1998.

            The Company believes that its borrowing capacity and funds
            generated through operations will be sufficient to meet
            currently foreseen capital investment and working capital
            needs in support of existing businesses for the balance of
            1999 and in the longer term.

            OF RESULTS OF OPERATIONS:

            Quarter ended September 30, 1999 and 1998

            Net sales for the quarter ended September 30, 1999 were $29.0
            million, down $2.4 million, or 8%, from $31.4 million for the
            corresponding period in 1998. For the third quarter of 1999,
            excluding the effect of acquisitions made subsequent to
            September 30, 1998, the Company's operations reported reduced
            net sales of approximately 15% overall. The decline in net
            sales at previously existing operations resulted from weakness
            in orders at facilities serving customers in the commercial
            aerospace and oilfield equipment markets.

            Gross profit for the third quarter of 1999 was $7.9 million,
            down $1.8 million, or 19%, from $9.7 million in the third
            quarter of 1998.  The Company's gross margin in the third
            quarter of 1999 was 27.1%, compared to 30.9% in the
            corresponding period of 1998.  The gross profit decrease in
            the third quarter of 1999 versus the same quarter of last year
            related mainly to the lower sales volume and a shift in sales
            mix toward somewhat reduced margin business.

            Selling and administrative expenses for the third quarter of
            1999 were $4.5 million, compared to $5.2 million in the third
            quarter of 1998.  The decrease resulted largely from cost
            reduction efforts within the Company, a lower level of expense
            associated with the management bonus for the 1999 period and
            higher bad debt related expense recorded in the 1998 period.
            Selling and administrative expenses as a percentage of sales
            were 15.6% for the third quarter of 1999, a decrease from
            16.6% in the corresponding period of 1998.

            Interest expense net of interest income in the third quarter
            of 1999 was $546,000, compared to $510,000 in the third
            quarter of 1998.  The increase resulted from a higher level of
            debt in the 1999 period related primarily to acquisitions made
            subsequent to September 30, 1998.

            Reflecting the above, net earnings in the third quarter of
            1999 were $1.7 million, down from $2.4 million for the
            corresponding period of 1998.  Diluted earnings per share in
            the third quarter of 1999 were $.28 as compared to $.41 per
            share in the third quarter of 1998.  The number of weighted
            average shares outstanding and equivalents was higher in the
            third quarter of 1999 by 274,000 as a result of the sale of
            shares of common stock in a public offering in the third
            quarter of 1998.

            Nine Months ended September 30, 1999 and 1998

            Net sales for the nine months ended September 30, 1999 were
            $92.7 million, a decrease from the $95.3 million reported in
            the corresponding period in 1998. The decline in net sales
            resulted from weakness in orders at facilities serving
            customers in the commercial aerospace and oilfield equipment
            markets.

            Gross profit for the first nine months of 1999 was $27.1
            million, down $2.6 million, or 9%, from $29.6 million for the
            same period of 1998 as a result of the lower net sales and a
            shift in sales mix toward somewhat reduced margin business.
            The Company's gross margin in the first nine months of 1999
            was 29.2%, compared to 31.1% in the corresponding period of
            1998.

                                         -9-

            Selling and administrative expenses for the first nine months
            of 1999 were $14.3 million, 5% below the $15.0 million
            reported in the first nine months of 1998. The decrease
            resulted largely from cost reduction efforts within the
            Company and a lower level of expense associated with the
            management bonus for 1999.  Selling and administrative
            expenses as a percentage of sales were 15.5% for the first
            nine months of 1999, down from 15.8% in the corresponding
            period of 1998.

            Interest expense net of interest income in the first nine
            months of 1999 was $1.6 million, compared to $2.1 million in
            the first nine months of 1998.  This decrease resulted from
            lower average borrowing levels during the 1999 period, and
            from an increased level of interest income related to notes
            receivable received during 1998 and early 1999 from the
            divestiture of the discontinued Precision Products operations.

            Reflecting the above, net earnings in the first nine months of
            1999 were $6.6 million, down from $7.5 million for the
            corresponding period of 1998.  Diluted earnings per share in
            the first nine months of 1999 were $1.10 as compared to $1.41
            per share in the first nine months of 1998.  The number of
            weighted average shares outstanding and equivalents was higher
            by 685,000 in the 1999 period as a result of the sale of
            1,000,000 shares of common stock in a public offering in the
            third quarter of 1998.

            Possible Effects of Year 2000:

            The Company categorizes its exposure to Year 2000 issues as
            follows; information technology (IT) systems at its operating
            facilities; IT systems at its corporate office; embedded
            technology; customers; and suppliers.

            The Company's IT systems at its operating facilities are,
            generally, maintained by Company personnel. The Company has
            upgraded its existing software used for order entry, billing,
            plant routing, shipping and process management to make it Year
            2000 compliant.  No additional employees were hired, nor were
            any additional costs with outside vendors incurred, to revise
            the existing software for compliance or to install upgrades.

            The Company's corporate office utilizes IT systems supplied
            primarily by third party vendors for accounting functions and
            payroll processing.  All such vendors have stated that their
            software is now Year 2000 compliant, and the Company has
            verified compliance as of the end of the third quarter of
            1999.  The Company pays annual maintenance fees for the use of
            this software, and no additional costs have been incurred
            related to this area.

            The Company's operations primarily involve furnaces and
            ancillary equipment.  Some of these use embedded technology
            such as microprocessor-based process controllers.  It has been
            determined that the embedded technology used in the operations
            is not date sensitive in many cases, or is Year 2000 compliant
            in others.

            No single customer accounts for more than 3% of the Company's
            sales.  In addition, the Company serves over 10,000 customers.
            The effect on the Company of the loss of sales from a single
            customer due to a Year 2000 issue, therefore, will largely be
            mitigated due to the Company's diversified customer base.
            However, there can be no assurance that individual plants will
            not be adversely affected by the temporary loss of one or more
            major customers.

                                        -10-

            With respect to suppliers, the Company's largest costs,
            excluding labor, are electricity and natural gas.  In the
            event a utility supplier cannot provide its service for an
            extended period due to a Year 2000 issue, the locations
            involved would be adversely affected.  It is not feasible for
            the Company to arrange alternative power sources due to the
            level of demand involved.  Short-term disruptions are not
            expected to have a significant impact on the Company due to
            geographic dispersion of the Company's facilities.  Other
            purchased items used in the operations are available from many
            suppliers and there is little or no product differentiation.
            A disruption related to these suppliers would have little
            impact on the Company.

            While subject to speculation, the most reasonably likely worst
            case scenario is currently considered by the Company to be the
            loss of either electric or gas power at an operating facility.
            However, the Company believes that this would be localized
            and tend to be of a short duration.

            The Company also benefits from having over 99% of its sales
            generated within the United States, which has given the Year
            2000 issue a high focus.

            The Company has designated a group of management personnel to
            coordinate Year 2000 activities.  This group is establishing
            Year 2000 contingency plans in advance of the Year 2000.

       PART II. OTHER INFORMATION

       ITEM 1.   Legal Proceedings

                 The company was the subject of a pending investigation by
                 the government and a qui-tam (whistle-blower) lawsuit
                 regarding alleged violations of the Federal False Claims
                 Act and wrongful termination.  The company learned of the
                 lawsuit in May 1998.  The activities that were the
                 subject of the investigation and lawsuit related to only
                 one plant, and in the fourth quarter 1998, the company
                 established reserves for the potential settlement of this
                 claim.  In the first quarter of 1999, the company reached
                 a settlement in principle with the government and the
                 plaintiff on terms consistent with the reserves
                 previously established.  The company completed the
                 settlement in the second quarter of 1999.

       ITEM 3.   Quantitative and Qualitative Disclosures about Market Risk

                 There has been no material change during the first nine
                 months ended September 30, 1999 from the disclosures about
                 market risk provided in the company's latest annual report
                 on Form 10-K.

       ITEM 5.   Other Information

                 On October 22, 1999, the Board of Directors adopted
                 amendments to the company's By-laws.  The effect of the
                 amendments was to:

                 .  Change the date of the annual stockholders' meeting to
                    the last Friday in April.

                 .  Change the advance notice provision that requires a
                    stockholder to notify the company of his or her
                    intention to present a proposal at the annual
                    stockholders' meeting a specified number of days prior
                    to the annual meeting or the mailing of proxies.  Under
                    the amended By-laws, in order for a notice of a proposal
                    to be timely it must be received by the company not less
                    than 60 days nor more than 90 days prior to the anniversary
                    date of the immediately preceding annual meeting.  Failure
                    to meet this timeline allows the company to exercise
                    discretionary voting authority on the proposal when and if
                    raised at the annual meeting.

                 This is only a summary of the amendments.  Interested parties
                 should read the relevant provisions of the By-laws for a
                 complete explanation of the notice requirements.  The amended
                 By-laws are included in their entirety as Exhibit 3 to this
                 report.
