Toolmaking
The modern ma-
chine shop depends
on skilful toolmak-
ers and their product.
Unique opportuni-
ties await men in the
designing and mak-
ing of tools and de-
vices for special op-
erations. Print does
not keep up with this subject, but there
are a few important books.
Markham's Toolmaking is practical
and instructive, written by an experi-
enced engineer and teacher.
Modern Toolmaking Methods,
by Jones, contains material from articles
by expert workers which have appeared
in Machinery, some of them being in-
cluded in Machinery's well known
Reference Series.
Toolmakers' Kinks, by Colvin and
Stanley, is a handy little volume of
practical hints originally scattered
through issues of the American Machi"-
iss.
