Flaperised the school run Surly Big Dummy so I can collect and jar-up the now abundant road chutney.

That's a supremely beefy looking steed!

The older I get, the faster I used to be ...
Finished swapping tyres on the Orbea Gain. Replaced the original 28mm Kenda Krampfish tyres with 28mm Continental GP4000IIs'. Total weight saved around 500gm. Interestingly the Conti's are actually fatter than the Kenda tyres, and the original Kenda tubes are actually quite light for 28mm at 110gm each.

All Surly's seem pretty beefy to me. Well made bikes, though.

An eBay purchase arrived yesterday. Broken. 
So I fixed it
A lucas comet bell
One of the mounting lugs had snapped off. Sure I could have sent it back, but by then I liked it too much! And I like mending things
I dont currently have a suitable bike to fit it too at the moment, but I'm sure I will at some point

Hmm. The front flap shimmies over 30kph. We sound like a run away didgeridoo. Design ideas to stabilise it?

Blinded @Cranky Knee Girl on a recent, wet 200 Audax (Raglan Castle) with my impressive rooster tail. So I fitted these on my lunch break. Club colours an’ all. Smart eh?

If the noise is speed specific it suggests it's hitting a natural frequency - two ways of changing this, either changing the structure or the mass. I would try changing the mass of the flap as in this case its the easier option. I would tape small weights to the flap and move them around until they're having the desired effect before making a more long-term adjustment, maybe riveting on an aluminium plate or something. Depends how much mass is required and where really, have a play and let us know how you get on

V. nice - is that home made or shop-bought?

This is a Raw product. Reflective too!
The one on the school run bike is home made.

You were a scientific inspiration. I fitted a cable tie about 40mm either side up the mudguard stay to the front rack. To the untrained eye, it is invisible. The shimmy is no longer and the bike is silent for the first time in over 5000km.
I suspect in my mind’s eye, I am faster than I have ever been!

Repaired a puncture. Was feeling pleased, had a shower, and now the tyre is flat again. Ggrrrr...

So....you didn't repair a puncture. You just swapped punctures.
