The cold-drawn process IS now large
ly restored to in the production Of steel
tubing. and Is a great factor In the con-
struction OF the bicycle, and Involves
machinery both ponderous and powerful.
one Of the methods employed consists
m taking a piece OF steel In the shape
OF a bar or ingot. This is bored through
the centre. and II Is then passed through
a die, after which It Is heated and
treated 10 a bath In a secret prepare
ton which removes the temper that the
drawing process imparts This Is re-
peated a number OF times. each die used
being smaller than It's predecessor. with
the result that the tube grows smaller
and longer. This is continued until the
tube is OF the right diameter and gauge

this manner. without heating II. Is re-
garded as a notable example Of the per-
lection Of modern machinery
