Workhorse of
the machine shop. Does so many different jobs so well. Use it on lathes,
millers, grinders, planers, shapers or drill presses to check a wide variety
of dimensions on many different size and shape parts without removing them
from the machine. Checks internal or external runout, eccentricity, roundness,
radius, taper, height, flatness, depth or thickness of parts while they
are stationary or in motion. Displays changes from pre-established settings
during the machining process. Case hardened holder fits most tools posts.
Furnished in durable, fitted case. Weight 2 lbs. Also available with upright
indicator (Model 22C). |

| These well known Ames gages are the
economical answer to many gaging problems, especially when dimensions
are difficult to reach. While models 12 and 12B serve a majority of requirements,
Ames has many special jaw designs on file (a few shown below), one of which
may be just what you need.
Only Ames calipers incorporate an
error compensating cam (see right). Each gage has a dust tight fulcrum
for long life operation. Indicators have shockless movement. Jaws are made
of heavy gauge steel for stiffness and long, trouble free service. |

Correcting Cam |
| All caliper
gages have the inherent problem of cosine error. Only Ames caliper gages
incorporate an error correcting cam (above) which compensates for this
error, so you can count on greater accuracy when you buy Ames. |
