Didn't think it could be 360* out but I didn't want to sound any more thick than I already do.

I will try your method xr2wishy but I think I will have to leave it for another day, its starting to get dark and I would rather take my time and do things properly. I cant afford any more mistakes and I don't fancy taking the head off again. I'm sure I'll get there eventually!

You've been a massive help xr2wishy

Thanks

Just one last little question: Would it be worth buying a dial guage?
