Assembling scooters

 

Building Vespas at the Piaggio factory.

One of my vices is vises, Nippon #140

A big solid vise from Japan with 4" jaws, but not much more info online that that.

1937 Red Hunter engine cutaway drawing

Back before valve spring technology was perfected, they used to be run out in the open to keep them cool. In 1937, Ariel introduced a sheet metal valve cover for the valves. It was short-lived, the next year came real modern alloy covers with screw-in caps for adjustment. 

 

International Harvester wrench

Just a fairly common M231 wrench, intended use long forgotten...  Many more of these agricultural equipment wrenches here.

 

44 foot yacht

This might be the stupidest thing I've ever seen manufactured...

When I found this image, I figured it had to be a joke, who would take the time and trouble to fit a big heavy motor into a flexible flat track frame? But no April Fools, apparently it's real.

Citroën DS convertible drawings

The convertible version of the DS was designed by Henri Chapron and introduced in 1958 to rave reviews.  The coachbuilder was approached by Citroen to create a production version, which became available in 1960.

Monday Mystery, short wrench

Here's an odd 1 1/2" wrench with an unsually short handle. It must be part of a system that utilizes a slip-on type handle, possibly formalizing the 6 foot pipe-persuader process, so favored by us hacks.

 The printed text "DWG ####" and "TLD ####" don't seem to help in a google search.

 Someone must have these in their toolbox, thoughts?
