Another job you wouldn't want to do: Beading holloware and hanging ware

(I think the vise at the bottom of the drawing above is more accurately referred to as a "hand vise.")

Below, my small selection of pin vises:

The one at the bottom is particularly interesting.  On the Web, it is usually referred to as a pen-style watchmaker's pin vise.  The knurled knob at the end unscrews to reveal a cavity in the handle for storing probes or drill bits.

Pin vices have been around for a while.  Below, the Goodell Brothers Company Pin Vise from 1896:

"Sonny" Levi and the Speranzella

John Bohannan.  Your Guide to Boating Power or Sail.  Barnes & Nobles, 1965, 1969.

"Sonny" Renato Levi was born in Genoa (or Karachi) in 1902. (The name 'Sonny' was bestowed by an ayah who could not manage the letter 'r.')  His father was an interior designer and manufacturer, but also an enthusiastic motor-yachtsman.  As a result, he found himself in the boat-building business, doing contract work in Bombay for the Indian government.  Sonny was in Cannes when World War II broke out.  Here the stories diverge.  In one, he joined the RAF.  In another, he became a real-life James Bond, passing misinformation on to the Germans and becoming the subject of a 2015 book: Doublecross in Cairo.  Somewhere along the line, he is supposed to have studied aircraft design and joined his father's business after the war.  In 1960 he moved to Anzio, Italy to work for Navaltecnica, which specialized in rough water patrol craft for the government.   During his tenure, he counted among his customers rich, playboy powerboat racers such as Gianni Agnelli, Count Augusta, and the Aga Khan who were prepared to fund his more daring ideas.  Levi pioneered the design of radical deep-V racing hulls.  His A'Speranzella was the 1963 Cowes-Torquay winner.

Schneider Trophy racer, Supermarine S4

 The Supermarine S4 was an R J Mitchell design for the 1925 Schneider Cup contest, held in Baltimore. It was a radical departure from the previous Flying Boat biplane designs, being an all-wood monocoque monoplane with externally unbraced wings, to which a steel framework was constructed ahead of the wings to attach the engine. It set a new World speed record before the event of 227 mph. Unfortunately during the elimination trials, the plane crashed into the sea and was too damaged to continue. The design was perhaps a bit too advanced, the crash was attributed to wing flutter. The race was won by Billy Mitchell in the Curtiss racer, at an even higher speed than the one set by the S4. Image above, engine tests at the Supermarine factory.

Across America by Motor-Cycle, 1919

On June 13, 1919, ex-RAF pilot C.K. Shepherd rode his Henderson-4 (named "Lizzie") across America, arriving 4,422 miles later in California on August 7th of the same year.  It's a fascinating read!

The images above are from an electronic version digitized from, oddly enough, a copy presented to the University of Toronto in 1980 by the Ontario Legislative Library.  What the book was doing there will forever remain a mystery.  You can download it at the Internet Archive.


In 2010, a blogger named Chris decided to trace Shepherd's cross-country journey on a modern motorcycle.  Read his adventures at Across America by Motorcycle.
