Have tried it for a blast pot gun BUT you do need to get the right (older type ?) plug as most (well the daughters fiesta ones) have a hard section in the center electrode about half way through. Think older plugs would almost come a part once separated from the metal threaded part.

I used to do it, takes about a minute to drill down the centre electrode. I would do a few at a time.
And very expensive :Pbut carbide is better so don't bother

http://www.ebay.co.uk/itm/TUNGSTEN-...hash=item33cc133acc:m:mgoP9LooLdOOm8BU3DC_XvQAhahah yeah I was searching right now and also found those. I will probably use the spark plugs in the start and when I get more money I will try to buy the carbide one. The carbide one looks straight how does it stay "stuck" to ball valve? Shouldn't it be conical?oops there 17 quid not 7

cut the ball valve off blast hose and fit direct in to hose using a jubilee clip and work pot from ball valve on air supply
Until I buy the the tungsten nozzle I am going to try the car spark plugs, but my "sandblast gun" is a 1/2" ball valve which has more than 10mm hole and the small hole of the spark plug is 3mm how do I evenly reduce the size (is there like any rubber piece?), I tried it without anything and the gun gets jammed with abrasive
