ITEM 2.  MANAGEMENT'S DISCUSSION AND ANALYSIS

OF FINANCIAL CONDITION:

At March 31, 2000, the Company's total debt was $42.4 million, a decrease
of $1.0 million from $43.4 million outstanding at December 31, 1999.  The
Company's total debt to capitalization ratio was 41% at the end of the first
quarter of 2000 as compared to 42% at the end of 1999.  The level of debt
decreased in the first quarter of 2000 as a result of cash generated through
the Company's operations.

The Company maintains a revolving credit facility with a total borrowing
capacity of $70 million.  The maturity date of the agreement relating to the
facility is December 2001.  At March 31, 2000, the Company had $34 million of
available capacity under the revolving credit facility.

Capital expenditures for the first three months of 2000 were $1.8 million, a
decrease from $2.7 million in the corresponding period of 1999.  The spending
in the first quarter of 2000 related primarily to the acquisition of
additional furnaces and equipment for expansion at certain of the Company's
facilities.

On January 28, 2000, the Board of Directors declared a cash dividend of $.08
on each share of the Company's common stock, payable on March 1, 2000.  The
total cash dividends paid on the latter date were $453,000.  This compared to
a dividend payout of $.08 per share of common stock, or $471,000, in the
corresponding quarter of 1999.

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
2000 and in the longer term.

OF RESULTS OF OPERATIONS:

Quarter ended March 31, 2000 and 1999

Net sales for the quarter ended March 31, 2000 were $30.2 million, down $1.9
million, or 6%, from $32.1 million for the corresponding period in 1999.  The
decline in net sales resulted primarily from reduced order rates, in
comparison to the year-ago quarter, at Company facilities serving customers in
the commercial aerospace and oil-field machinery markets.

Gross profit for the first quarter of 2000 was $8.3 million, down $1.5
million, or 15%, from $9.8 million for the first quarter of 1999.  The gross
profit decline in the first quarter of 2000 was the result of the decrease in
net sales for the period, offset to a degree by cost reductions.  The
Company's gross margin in the first quarter of 2000 was 27.4%, compared to
30.4% in the corresponding period of 1999, reflecting the effect of the
relatively fixed cost structure of the Company's operations and the limited
opportunity to reduce costs to offset sales declines in the short term.

Selling and administrative expenses for the first three months of 2000 were
$4.9 million, down slightly when compared to $5.0 million in the first quarter
of 2000.  Selling and administrative expenses as a percentage of sales were
16.3% for the first quarter of 2000, up from 15.6% in the corresponding period
of 1999 as a result of the lower level of sales.

Interest expense net of interest income in the first quarter of 2000 was
$668,000, compared to $530,000 in the first quarter of 1999.  The increase
resulted from both higher average borrowing levels and increased interest
rates in the first quarter of 2000.

During the first quarter of 2000, the Company received a cash dividend of
$118,000 from Thixomat, Inc., a business in which it owns a minority interest.
No such dividend was received in the first quarter of 1999.

Reflecting the above, net earnings in the first quarter of 2000 were $1.7
million, down from $2.5 million for the corresponding period of 1999.  Diluted
earnings per share in the first quarter of 2000 were $.30 as compared to $.42
per share in the first quarter of the 1999.  The weighted average shares and
equivalents outstanding for the first quarter of 2000, compared to the same
quarter of 1999, was lower as a result of the purchase by the Company of
264,000 shares of common stock for the treasury in December 1999.
