Dear Sir:
The purpose of this letter is to set fo costs of ckaags tasted
by the Government on the referenced contract. N ehan.os is addition
to theme presented previously. Details of the changes are Orden below and a
cent summary is included as Attachment A.
1. In January 1959 Government representatives requested a cbafte

it was found that this diagram called for connections to plugs which did net
exist on the schematics of the individual units. In order to connect as. 4-12,
it was necessary to reconstruct from theory the connections necessary to make
the unit operative. A number of changes were required on panels already wired.
4. Plugs on both power supplies were reversed from orientation
shown on customer's assembly drawings. The input terminal block was over-
width on the High Voltage power supply and had to be hand filed to bring it to
dimensions. The HV power supply contained a relay that was already wired
into the timer. This relay had to be shortened to make the unit operative.
5. The latest drawings furnished by F-Icentained the following
a. Location of the idler cluster gear was incorrect, causing
the gears to bind. This was corrected by making the idler cluster gear mount-
ing arm adjustable, which necessitated disassembly of the unit and do enlarge-
ment of the locating hole in the upper plate.
b. The new design tape take-up spool has an adjustable slip
clutch. No clearance was provided for the adjusting nut. Since machining
clearance on the motor housing required complete disassembly, new clutch
springs were made of a thinner material so that the adjusting nut could be
turned high enough to clear the motor housing mounting flange.
c. The bend specified on the initiate switch actuator is incorrect.
5 order to make the switch operative, the actuator was rebent and adjusted
after assembly.
d. The Write switch bracket interferes with adjustment of the
uaamnstater. These were rebent and filed to fit.
e. The upper tape supply and tape take-up tool bearing were
too long. . 018 inch had to be removed from each bearing to permit the parts
to mate.

6. When costs were developed on the panels. frames and b ttun plates
of the instrument case$, it was planned to obtain castings from the same source
as and use their pattern equipment. This was to result in a daring to 25X1

These were cleaned. up and partially machined to determine their iasbllity.

bt all cases it was found that some revised dimensions adversely afteled the
plates and in all cases the panels were too thin. They were alwdNSd and
the new plates were machined from solid plate.
The only alternate to the cast frames was to fabricate from estrudsd
channel. Here the costs exceeded. by a considerable amsstat, the cost of the
cast frame. The cast frame would have required only machining two surfaces
and drilling and tapping mousing holes. The fabricated frame required fab-
rication, machining top and bottom machining clearance for "rivals", drill,
countersink and installation of "rivnuts".
7. The Exciter R4 unit was not designed by until October 25X1
115$ and a schematic was not furnished until late Novem r. No mechanical
or detailed drawings were made available until late December. Components
were ordered from the schematic. Chokes were not specified on the schematic
except for inductance values. Because of an ordering doadltne, after exhaust
tag all possible sources of information on the chokes, the inductances speci-
fied on the schematics were sent to and the coshes ordered. 25X1
Drawings of the pie and choke did not specify inductance. The assembly draw'
ing calling for NTT chokes was not received until two weeks after our order
for chokes was placed. Specifications for the pie wound choke and the filament
choke were not received until the R4 unit was returned fromF--Iin March. + ' 25X1
In addition, the only information available for winding coils was that
gives an the schematic. Unknown factors were "Q", size of wire, ett. After
receiving the unit back in )(arch, a drawing was received giving the coil wiadli-
ing data., The coils had to be, rewound to get necessary bandspread. lfewever,
even the data on the drawing had to be reworked because the number of turns
given did not give the inductances specified. This entailed considerable "cut
and try" to obtain specified values. This work was quite difficult because of
limited space and the heat sink grounds which prevented direct wiring to the
ground.
Two of the mechanical drawings (321515 and 321512) were is error,
requiring refabrication of some parts.
8. The luminous paint specified for the panels is savable as en-
gravers paint an painted surfaces. This paint contains a vekiclo that is
absorbed by either enamels or lacquers. As a result, the *arose pout that
must be removed when filling engraving damages the tiatkgrouad paint. it
is satisfactory on anodized or unpainted surfaces only.. 1ls panels had
to be stripped and repainted before acceptable eagravlg was sealtaed.
