Re: A small piece of metalwork - mounting an Aura 100 lamp on the fork

Due to the large Ortlieb Classic on the handlebars, there is no sensible
mounting position for the Aura 100*) on my current road bike.

  However, the fork blades each have three threaded bushes at the usual
distance, which are suitable for lowriders or three-point bag holders.
As I couldn't find a commercially available mountable lamp base, the
only option was to make my own. I passed on a similarly constructed
holder I bought decades ago, which was attached to a fork tube with a
steel strap, to one of our children and it is still in use. But I
wouldn't have been able to use it on the carbon fork anyway.
 So I built my own.

  My attachment for the fork consists of a bent section of an aluminum
flat profile, a section of an aluminum tube, a washer made of sheet
steel and a matching screw with hexagon socket that connects the tube to
the flat profile. To ensure that it holds without gluing, I shaped the
flat profile (bent it several times) so that it protrudes into the tube.
Finally, I cut a thread in the middle to match the screw. The thread
will perhaps get some thread locking adhesive, but I haven't yet decided
whether I will replace the screw with one with a flatter head and
whether I will glue the steel washer and the profile in place.
 I don't expect to use the lamp very often, but it is reassuring to be
able to use it properly when it is needed. The whole construction is
easier to mount than a bottle cage, using a small hexagonal wrench and
two screws.
