Re: rocket tank [TANKS]

["Peter Arundel" <pureteenlard-at-hotmail.com>]

With the lack of firearms in blighty, I mispent my youth building cannon out 
of whatever I could find lying around the metal work rooms at school. For 
powder it was either crushed up match heads, black powder from agricultural 
crow scarers or, eventually, cartridges meant for Hilti guns. The last one 
of these devices was built from the kingpin from a Morgan 4/4 and was 
chambered for hilti cartridge and 8mm steel ball bearings. It was clamped in 
a machine vice and fired by giving the breach end a hefty tap with a hammer 
. . .

On the rocket front we did manage to launch a firework, polaris style, from 
8" underwater.

Not sure why we did it except to see if we could.

Pete.
