Or more boringly does anyone have an physical information about Nobel No. 6 detonators? Size, fuse end length, were they only used with safety fuze, all that sort of stuff.

We have a box as part of the demonstration exhibits on the Carrs Mine tours and it would be nice to have something that was the right size. Probably only matters to me but it is nice to get things right. Smile

No 6 dets were (are?) available in plain (for crimping on to a fuse), capped fuse & electric versions.
The plain I've heard referred to as the "plain azide detonator" as the base charge was lead azide. They were only really suitable for the older high sensitivity secondary explosives (NG based), black powder or det cord.
They were superseded by the no. 8 (more correctly the #8 or 8 star to avoid confusion with delay numbers).
These have a higher weight base charge (usually PETN, TETRYL or DDNP) which makes them suitable for the more modern lower sensitivity secondarys based on AN gels ect. & the "plastics".
Somewhere in my shambles of a filing system, I have the ICI "Detonators" data sheet - if I can find it. However, I have found my copy of the ICI "Initiation" data sheet, which I've scanned. If you PM me your email address, you're welcome to a copy.

I can show you some no 6 det's if you want to play with one nick, next time you fancy dropping in to the hole in the floor club there's a few dotted about, and tins too still in paint with instructions and sawdust!
