Tools that made tools

Consider this: every tool or machine was made by a tool or machine.  So there are factories full of tools and machines that do nothing but make tools or machines.  For the connoisseur of fine machines, the tool-making tool is highly sought because it is usually well maintained and precise.

Imagine the excitement in the Northwest Railway Museum's Conservation and Restoration Center when word arrived of an opportunity to tour the shop in Yakima where the Century lathe was built.  Now imagine the excitement when they learned it was possible to buy some of the machines to equip the Museum's collection care center. 

Store front for McIlvanie
Machine Works in
Yakima, WA.
Opened in 1922, the McIlvanie Machine Works made the famed Century Lathe at their facility in Yakima.  (The shop has a heritage rail connection too: it fronts the Selah branch of the Yakima Valley Transportation Company interurban line, a former Union Pacific property now owned by the City of Yakima and operated by the Yakima Valley Trolley.)  The last owner passed on and family heirs chose other career paths.  And certainly the machinery is out of date: there is not a computer anywhere to be seen.  These machines are old-school, relying entirely on the skill of the machinist, and exactly what a railway museum needs to maintain Century-old machinery!  So please enjoy a few photos of what has become a rare resource: a machine shop without CNC (Computer Numerically Controlled) capability.



A famed Century lathe, though this one probably never left
the factory. It is on the production line and was used to
produce parts for new Century lathes.
 
American Pacemaker lathe.

A McIlvanie drill press, probably the
prototype.  Note how it operates from a
driveline.  You changed speeds by
selecting a larger or smaller pulley
diameter.
 
The pattern for the McIlvanie drill press.  This aluminum
pattern was pressed into casting sand.  Then the molten steel
was poured into the void that the pattern left behind. 


Overhead drivelines were located throughout the front shop.

The capstan on a turret lathe.  Different holes can be machined
into a piece mounted in the lathe chuck.  The turret or capstan
can be turned to each tool bit so it can be used over and over
again without having to remove and reinstall the bit.

The speed selectors on a Century lathe.

Thread cutting tool.

Radial arm drill press, and this one will
soon be inside the Museum's Conservation
and Restoration Center!
