My crew mates at the coastal marine station all had shiny Vibroplex bugs
they carried around in velvet lined wood boxes. They were all lightning
fast on the dot side, and various "methods" were used to slow them down.

scroll down to Les Burger on the right for an example. My beat up J-36
by Lionel [$5 at Surplus Sams] that I carried in my backpack would
easily slow to 10 WPM, the leaf spring was about half as thick as a
Vibroplex. Putting more weight on the armature will slow a Vibroplex,
but it's also additional weight you have to slap around, and can lead to
an "interesting" fist.

Vibroplex makes several different weights for these bugs. However, I
always just used the large solder wrapped on top of the original
weight. The new weights are on this page:
