Is the Best Place to Run Old Windows Software…on Linux or a Mac?

A few years ago I put out an article entitled Partying Like It’s 1987: Running WEAP87 and SPILE (and other programs) on DOSBox, where I describe the use of DOSBox in running engineering software (and also Windows 3.1.)  A great deal of engineering software developed in the DOS era can still be used for engineering design … Continue reading Is the Best Place to Run Old Windows Software…on Linux or a Mac?

A Gathering for Energy Savings

Above is an unusual photo from Vulcan's archives: a gathering for a test for the Vulcanaire Supertherm at the yard of Horn Pile and Foundation Corp. in Bellmore, Long Island, NY, 16 November 1964.  It's the rare gathering in the construction (or just about any other) industry where everyone arrives in suits, but here they … Continue reading A Gathering for Energy Savings

"Chet" Warrington, my grandfather.  He put a wrap on the … Continue reading Liberty, Prosperity and Life

Riding High in Beijing

During Vulcan's first visit to Beijing in 1981, we saw many vehicles on the road we had never seen before.  One of them was the Hongqi (Red Flag) limousine.  The one above was parked in front of the Beijing Hotel, where we were staying. Jay Leno's Garage featured one back in 2016; here's the video … Continue reading Riding High in Beijing

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

“Much Favorable Comment” for the Vulcan Extractor

An ad in Engineering News-Record, 8 October 1931, for the Vulcan Pile Extractor.  It was used to extract arch web Lackawanna sheeting by the P.J. Kennedy & Co. of Holyoke, MA.  Vulcan touted the advantages of a "single purpose machine" (as opposed to MKT's multipurpose hammer/extractors.  MKT must have gotten the message, they developed the … Continue reading “Much Favorable Comment” for the Vulcan Extractor
