    Going to need one of those modern splined BB tools as the current Brompton JIS model uses that.

    The 10 yr old Brompton is getting the new spider chainset. It needed a new BB anyway.

    The 2013 Brompton needs a new RH pedal but it's stuck. Once the 10 yr old is running I'll try removing the pedal with FIRE!

    SuperLight was out today and will probably be used for the rest of the week unless it rains.

    Chains and sprockets to be replaced on both of the steel ones.

    "I'll try removing the pedal with FIRE!"

    Hot air is less destructive.

    Not sure exactly what they use, but Bike Works removed a VERY stuck BB cup with some sort of 'large hairdryer' and TWO people using tools.

    £12 - but worth it (I'd already tried most things - not fire though).

    Well… when I say fire it will be more like waving it near the Trangia gas burner.

    The Common Wheel in Maryhill burned the old BB out with the welding machine last week.

    Had to replace a broken brake lever on the pashley, after the bike tipped over and broke the lever off. Decided to stick with a Sturmey archer, but a slightly diffrenet model with comfy rubber bits for my fingers.

    Cue the fighting to try stretch the cable enought to fit into the brake lever. Take the bell off and shimmy the lever down the handle bar as far as it'll go, still won't go in. loosen the cable as much as it'll loosen, still wont go in. Shimmy, and loosen some more, still no success. Stuck.

    I don't want to cut the cable as it has a 'thingmy' on either end, so I can't simply undo, and adjust as with a modern system.

    Oh, that wee thingmy just pops off and the cable slides aling as much as you need it too...

    That'll be 45 minutes I never get back!

    At least the other lever went on without issue in a few minutes once I'd realised my incompetence.

    Over the weekend, due to a cold precluding much that was energetic I decided to deal with the sheared rack bolt on my tourer that has been awaiting attention since *cough*last August*cough*. Rack and mudguards have been using the same bolt ever since which offends my sense of neatness.

    Proudly clutching my new #3 EZ-out (or nearest Screwfix El-Cheapo approximation) I drilled out the bolt, rechucked with the EZ-out, reversed the drill and had at it. EZ-out went in just fine. Bolt didn't come out though. Drill clutch makes that distressing rattling noise. "Ho-hum" thinks I. "Better remove the EZ-out and find out what's happened".

    Accordingly switch drill to "forward". Same distressing rattling noise. EZ-out now very firmly stuck!

    Cue much violation of Rule 2, faffing with visegrips etc. Eventually extracted the EZ-out by using the Reynolds chuck adapter for my SDS drill. That, being an old-skool keyed chuck (and nice and wide to boot) could grip the EZ-out firmly enough and allow me to turn it with enough force to unscrew the EZ-out.

    After some consultation of the runes, I decided to drill the whole bolt remnants out and just put a new bolt through the whole, not bothering about tapping a new thread or inserting a helicoil. I then promptly utterly blunted my one 5mm drill bit requiring another trip to screwfix. With that out of the way, the repair seems to be holding up with only one Saturday morning lost, so far at least...
