thanks for the replies, thats the part, yet again though i wish i had listened to my dad, he was a classic motorcycle chap of the old school, when he offered to teach me some metal work skills and to braze because i would find it so much more rewarding making one from some brass pipe than giving melvyn rutter the silly amount of cash he wants for a bit of pipe.
Bit of pipe? Its a bit more than that. Labour at circa £50 per hour (plumbers circa £60- £70 per hour), fabrication, welding etc etc. Does not seem bad to me.
