Next with some help make manifold to put Fazer bike carbs on Elder head. Bloody cast one would be good but a one off cost would be too much Webers for now |

They mix stainless with aluminum all the time on modern cars so cant see to much of an issue. As for manifolds, shouldn't be to hard to make a couple. All you need is flange plates to suit head and carbs and some slightly bent pipe between. All part of the fun! |

Hi Guys Try using Duralac jointing compound It is chromatic containing, and inhibits electrolytic decomposition between dissimilar metals. It is a single pack air setting product which will prevent anode decomposition even in a harsh marine environment such as stainless fittings on alloy masts and booms on sail boats Available most marine distributors / ships chandlers that are involved in sailing It works Cheers Ian |

Carefull barium chromate isn't good to eat though, try not getting it on your skin in large amounts it can stick around a while. Used in aeroplanes as well as sailing boats. doesn't last forever though, well out on the water that is. |

Thanks guys .The softer my hands the better for me lol. The middle aged eyesight thing has caused repeat efforts. I have a computer cad program but it wont resolve less than 1mm And if you make it do it the job size diminishes im not buying expensive software. |
