June 25th – People have been asking me why I haven’t featured any pictures of the new leisure centre development at Oak Park yet. There’s a simple answer to that – it’s very, very hard to get good images of.

The site is huge, surrounded by trees and high hoardings, and you can’t get a good angle on it. But it does look like it’ll be nice; looking through the trees today I could see they had been digging the pools out under the steel frame.

It’s also a remarkably well-run site, with flowers planted outside the gate, and even water for passing dogs.

I’m watching it carefully, and as soon as there’s a better photo-op I’ll go for it.

June 24th – And by the canal in Leamore, just near Pratts Mill Bridge, a clump of purple vetch was proving irresistible to the bees, who buzzed around it with an air of frantic, but random purpose.

The vetch, like many other flowers is profuse this year. I hope the bees prosper from it. They need our support…

June 16th – Bottom brackets are a pain in the arse. I can’t believe that after more than a century of cycling technological innovation, they’re still so rubbish.

The bottom bracket is the spindle that the cranks mount on through the bottom of the frame, which spins freely allowing your pedals to rotate. As a mechanical component, the bottom bracket experiences the worst abuse – epicentric, unbalanced point loading, muck, water and corrosion. My bottom brackets take my full weight, plus that of the bike and load. They work hard.

Several solutions exist for bottom brackets – the component axle and loose bearings – the old way and fiddly to adjust and maintain; the ‘sealed cartridge’ (above) – a disposable insert designed for easy changing; the external – a frankly daft idea that’s gained traction in the last five years; the thoroughly insane press fit, preferred by the weekend Wigginses with plastic bikes.

All are rubbish, really.

On Sunday, I noticed the cranks on my bike had alarming play within the frame. The non-drive side bearing had collapsed in the cartridge. It’s done about 20,000 miles. Removing it is easy if you have the right tools and the person who fitted the last one did it properly. 

Cranks are removed with a special extractor, and the cartridge is removed with a special socket tool from the DRIVE SIDE. It is a left hand thread, meaning the unit is turned clockwise to unscrew it. That fact escapes many, and has led to loads of skinned knuckles and damaged frames.

The cartridge is left hand threaded to prevent it loosening in use due to precession.

There is a support bush on the other side that unscrews normally using the same tool. The threads are cleaned with a small wire brush and degreaser, dried, greased with anti-seize paste and the new one fitted. Half an hour tops.

If the threads are not greased, the unit will be very, very hard to remove in future.

A replacement is about £15-£20. I’ve tried expensive alternatives – they make no difference.

See you again in another 15-20,000 miles.

June 13th – So, the Watermead cygnets are down to five – this is definitely the family, spotted today near their nest. They started with seven and have lost two, which isn’t too bad – most likely to predators of some sort. The youngsters are growing well and seemed happy and healthy (as far as I could tell, anyway).

It’s so good to watch the local wildlife mature like this. You almost develop an attachment to the birds as they get older.

June 10th – Passing Goblins Wood (or Coppice Woods, for the hip modern kids out there), I noted how beautiful they looked. This mostly deciduous, well managed woodland is very old and suspect the only local remnant of the traditional English oak and holly copses that once dotted the area.

These woods, and the trees therein have seen many seasons, and every summer they look superb. Long may they remain (and they are protected by law now, too.)
