re-using old spark plugs

not as title suggests, but close..

I need to remove the ceramic insides from an old spark plug.. to make use of it for something else, and an old plug seems ideal.

I've pulled the electrode out of the center, so I do have a small hole down the middle..

I was thinking along the lines of hammering a tappered punch down the hole until it all shatters the ceramic..

any other ideas..

How about using an old skool tdc gauge? - pretty close to a spark plug with a hole down the middle.

Yes they do and hardly any noise is emitted when a toughened window is broken by the ceramic from a spark plug. Why is that? Secondly who discovered that?..Sorry for going OT.

Its not for breaking into cars, -I've been a victim and it isn't the most favourite thing I want to happen to me again..

-it's to repair the base of an up-lighter has fallen apart..

The ceramic is held in by the outer steel shell of the plug being crimped over. Cut through this in line with the top edge of the hex and the ceramic will fall out if you tap it from the combustion chamber end.

As BT says just cut above the hexagon and all the ceramic will drop out. Have done loads in the past to make adaptors to pressurise cylinders and to make head stands.
