I need to join a bicycle fork (28mm tube) to a scaffolding pole (48mm tube).

I need to join a bicycle fork (28mm tube) to a scaffolding pole (48mm tube). Since they are different sizes, I don't know how to join them. Any ideas?

      Wrap aluminum foul around the small pipe until it fits snugly into the larger pipe, then weld or braze it or do what said.

            Aluminium foil+10mm gap+steel scaffolding pole+bicycle fork (steel or aluminium?) We don't even know the strength of the 2 pipings - maybe the bike one is 1.8mm and the scaffolding is 3mm?

            How the fuck is that gonna end up with a proper weld or braze? For brazing you need a very thin gap, the foil is gonna ruin everything and welding together steel and aluminium isn't even possible.

    28mm and 48mm is an extreme difference.
    Personally I would build or purchase a reduction piece to bridge that difference and braze it together. If you do a proper job that will last forever.

    Take a 50mm piece of brass, make the internal hole. Put in a screw. Mount on a drill in a vise or a drill press.
    With a chisel reduce the diameter like you would do on a lathe.

      I think if OP had and knew how to use a drill press, chisel and lathe he wouldn't ask about connecting a scaffolding pipe to a bicycle fork

    You might even get them to weld it.
