Forge, anvils, tongs, swages, punches, bolt tools, hot and cold chisels,
blow-pipe, soldering iron, hard and soft solders, borax, spirits of
salts, oil, resin and spelter.

To this may be added an endless variety of small bench tools,
micrometers, protractors, arbors, collets, box tools and scrapers.

LARGE MACHINES.--The list would not be complete without the planer,
shaper and milling machine, with their variety of chucks, clamps and
other attachments, too numerous to mention.

The foregoing show what a wonderful variety of articles are found in a
well-equipped shop, all of which can be conveniently used; but to the
boy who has only a small amount of money, a workable set is indicated as
follows:

A small lathe, with an 8-inch swing, can be obtained at a low cost,
provided with a countershaft complete.

CHUCKS.--With this should go a small chuck, and a face-plate for large
work, unless a large chuck can also be acquired. This, with a dozen
tools of various sizes, and also small bits for drilling purposes.

The lathe will answer all purposes for drilling, but small drilling
machines are now furnished at very low figures, and such a machine will
take off a great deal of duty from the lathe.

As the lathe is of prime importance, never use it for drilling, if you
have a driller, as it always has enough work to do for tuning up work.

BENCH TOOLS.--Of bench tools, a 3-inch vise, various files, center
punch, two hammers, round and A-shaped peons, hack saw, compasses,
inside and outside calipers, screw driver, cold chisels, metal square,
level, straight edge, bevel square, reamers, small emery wheel and an
oil stone, make a fairly good outfit to start with, and these can be
added to from time to time.

Everything in the machine shop centers about the lathe. It is the king
of all tools. The shaper and planer may be most efficient for surfacing,
and the milling machine for making grooves and gears, or for general
cutting purposes, but the lathe possesses a range of work not possible
with either of the other tools, and for that reason should be selected
with great care.
