Machining a Cast Iron Bearing

Some of you may wonder what it was (and is) like to machine parts for Vulcan hammers, most of which are iron or steel castings.  Some feel for it (and the decisions a machinist must make in the process) can be seen in the video below. https://youtu.be/L5yVpvCav_U Some comments: Although he doesn't say so, my … Continue reading Machining a Cast Iron Bearing

Christmas Music at the Australian Avenue Office (Maybe)

When Vulcan opened it's Australian Avenue office in West Palm Beach in 1966, it wasn't long after that Vulcan acquired one of those continuous loop background music tape players (as depicted below) that graced many offices, department stores and malls of the era. https://youtu.be/d2tx5NHDcHA Background "easy listening" music was pretty much a fixture at the … Continue reading Christmas Music at the Australian Avenue Office (Maybe)

Hand drafting – TECHNICAL INK PENS — Construction and architecture

William H. Warrington was born 17 September 1846, grew up in Chicago, Illinois. He became the manager of the Vulcan … Continue reading The Art of William H. Warrington

The Stamp of Quality…Everywhere

Vulcan frequently produced an ad for the Offshore Technology Conference.  Probably the best one was the "Stamp Ad."  The "stamp of quality" theme had appeared in Vulcan's literature for many years before that, but Vulcan's graphic artist Carol Carr took it to a new level with this one in the early 1970's.  It was unusual … Continue reading The Stamp of Quality…Everywhere

The Vulcan Extractor Photo that Made a Civil Engineering Textbook

Vulcan hammers appear often in geotechnical engineering textbooks and other reference material.  It's rare that it would happen outside of that discipline, but happen it did. In 1960 the first edition of Mechanics of Materials by Archie Higdon, Edward H Ohlsen and William B. Stiles was published with the 1200A extractor photo shown above.  The … Continue reading The Vulcan Extractor Photo that Made a Civil Engineering Textbook

Indicator Devices and Cards for Vulcan Hammers

The indicator card, and the devices that produced them, have been around about as long as there have been steam engines.  The basic idea is simple: as the piston of the engine moved, a pressure indicator moved a needle and pen up and down on a paper (usually a rotating drum) and produced what's called … Continue reading Indicator Devices and Cards for Vulcan Hammers
