I am looking into ways of chemically removing rock in caves. I know all about using Caps and SLB etc, but what exactly are snappers. Lots of references to this on Forum but no explanation

No information for various reasons which I won't spell out.  Try following the link at http://eug.bcra.org.uk/ and join up.

Andy, what's the situation?

You might be able to remove them another way so it May(?) be worth describing what you've got (without giving away your lead if you don't want to).

I particularly like Plugs and Feathers as they give quite an elegant solution and (mostly) accurate cut, but they do use quite a lot of battery power.

Snappers are effectively gunpowder, so as Bob says it's worth going through EUG if you're considering using them. Although EUG are primarily concerned with High Explosives it would give you a good basis on safe practice.
You might even find that 'HE' are easier to come by in Yorkshire than Snappers.

OK, thanks for that. Already member of EUG. I will PM Nick W

i thought they where classed as compressed gas not gunpowder !!

Snappers are not compressed gas, and they are not gunpowder. Legally, they are the same as fireworks.

Bob Mehew's link is the best resource if you want to know more.

cheers nick
