    Joining/extending aluminium tube

    Humour me...... If I had an aluminium tube and I wanted to make it 2" longer, what are the options for doing such a thing?
    In my head, the obvious thing would be to cut the tube and internally sleeve it etc

    My plan is then to encase it in carbon.

    Any guidance on this would be ace

    Yes, I love a weird project! Maybe make an entire new extended dropout with a long insert to go in the existing leg and bond it in. You could convert to a more modern axle at the same time. Id avoid welding unless you know a friendly heat treatment plant, cost is very prohibitive.

    The axle is where I became a little unstuck.
    I'd contemplated buying a carbon rigid fork with a 15mm bolt through and disc mount attached, then somehow sticking the pair of twats together

    I don't know how, but I'm practical and happy to research

    I'm a plumber so if this was copper.....

    Something like this perhaps? With a non boost 15mm axle and disc mount already attached???

    I'm aware this is bizarre, but I've committed now

    If you want a disc mount as well i think i'd be fabricating a metal dropout like these MRP forks, and then sliding it over the existing tubes and bonding in place.
