the job should be as thoroughly
fooled up as is necessary in the pro-
duction of automobiles.
-Four thousand three hundred
and sixty-three tools, jigA fixtures.
and gauges had to be designed and
manufactured for this purpose. A
large number Of these jiga fixtures.
and tool bodies were made from
castings. 1905 different patterns had
to be designed and patterns made,
castings obtained. before the ma

these fixtures and tools required for
craft gun carriage. have lists Of
these tools which are a very interest
ing exhibit and illustrate. perhaps
as well as anything that could be
displayed, the immense amount Of
preparatory work required before a
gun carriage or any other similar
piece of equipment can be put into
production.
THE time required Of the en-
cheering organization Of any ma
chine shop or manufacturer in the
preparation for the manufacture of
an article cannot be ignored. and If
not provided for will stultify any
preparedness program.
Preparedness Program
I'm my opinion. an educational
order to q manufacturer will be Of
very little value In the preparedness
program unless the ordnance de-
partment is permitted and instructed
to include In that order. although 1t
is only for limited number of
articles. an order for the design and
manufacture OF all tools, fixtures.
and gauges that would be required
for the manufacture of the article
on a production basis.
These items are all special. can
not be designed and made in a min
ute, and IL not in the manufactur-
er's hands in time of emergency
would delay the manufacturer of in
tricate articles Of equipment far be-
yond the time for which they are
scheduled for delivery on the present
preparedness program.
these tools and fixtures could be
made In connection with the first ed
ucational order and stored by the
manufacturer or in government ar
senals, but could be used in subse-
quent preparedness orders and, by
their use. the economy in the manu-
facture Of the equipment. compared
with manufacture by tool room
methods without fixtures, would pay
for the tools in the manufacture of
very few units.
"As an illustration. the New Brit
ain Machine Co., under the present
preparedness program, is on the
schedule for delivery of six anti
aircraft gun carriages in the seventh
month, 10 in the eighth month. ~
in the ninth month and so on, and
the program calls for the same three

before you.

1.-THE New Britain Machine Co. has
made the special tools, jigs, fixtures
and gauges to the number of 4.363,
and they are now stored in the Rock
Island Arsenal. 1t would be posi-
BILE, with no change in design. and it
would be perfectly practical to ex-
pect the New Britain Machine Co. to
get into production and make the
deliveries called for on the prepared
ness program because the New Brit
ain Machine Co. has had experience
il manufacturing this particular gun
carriage and because the tools, jigs
and fixtures, above referred to are
available. However. the three inch
anti-aircraft gun carriage which the
New Britain Machine Co. made in
1917 and 1918 is being superseded
by a more modern gun carriage.
"A pilot gun carriage had been
made at the Watertown arsenal. II
this works successfully in tests, it
will be adopted and substituted in
the preparedness program for the
one with which We have had eX-
perience in manufacture. The de-
SRA bility. therefore, of not only the
New Britain Machine Co. but what
ever manufacturer assumes the re-
sponsibility for the manufacture of
the new anti-aircraft gun carriage
under the preparedness program. 10

manufacture of q few of these gun
