Cheers Screwdriver. 

Just a thought.  Are cheepie No-gas MIG welders any good?  Such as http://www.machinemart.co.uk/shop/produc.../010110125  Would that be any good?

Not done any welding since I was an apprentice over 25 years ago.
Oh apart from welding the front sprocket onto my old Fazer600 :eek a few years back.
