Fitted a tortec rack, that I'd bought for her birthday, to my Young Lady's bike. The bike, thankfully, has rack mounts on the seat stays (something I'd failed to check before buying the rack) but they are bottle type bosses facing rearward rather than outward.
Scrabbled in the Pot of Fasteners and turned up a couple of bits of stainless steel, originally meant as rear mudguard to mudguard bridge brackets. Bent these to the correct shape using my King Dick as a makeshift vice and another adjustable spanner. Channeling my inner Blondihacks/This Old Tony, I drilled holes, using some mole grips to hold things steady. Really really slow drill speed and plenty of pressure was the trick. After that it was straight forward. Quite Pleased with the result.
