Sales Manager, and Mr. Geffney or rw ftsineering 25X1A
y stated that on an order of our size (65 pieces
tinge would be practical. Bowever, only three of
the pieces, the frame block, the cover, and the case could be
cast by this method. It was pointed out that, in general, the
thinnest section economically feasible to sand cast was 3/16";
thinner sections would have to be machined.. All mounting surfaces
would have 1/16" machining stock remaining and no windows or holes
would be cast in the pieces.
3. The company indicated that the three pieces named above
would cost somevhat less than $1000.00 in lots of 65 each. The
quote is tentative and subject to revision based on finish ma-
chine prints which we would have to provide. The above figure
is very encouraging when savings in machine labor and tie-up are
concidered, A breakdown of thie vote and all pertinent infor-
