Hi Grumpy and Bruce,

Firstly thank you for your input as it has pretty much confirmed what I have still as a doubt, the spark itself. I love that custom made tool which is good for a single operator. What you've suggested is what I'm going to do this morning and I'll advise you guys of what the result is.

Cheers,
BB

I live a 24 Hour lifestyle, but every now and again I seem to fall asleep, well at least that's what my wife tells me.
