A good recyclist needs to keeps the ball rolling, getting ready for future projects, cleaning, rebuilding components, organising. While I often have only limited time for bicycle recycling, I try to find small projects that will help me later on.
For example, here is the unusual bottom bracket assembly for the Malvern Star Sportstar. This is the crux of the project as the bike is useless without it, due to the threadless BB shell. I’ve stripped it down, thoroughly cleaned and rebuilt the bracket with a JIS square taper axle ( replacing the cottered original ) and 22 brand new 1/4″ ball bearings.
The little seals each end will roll out with careful finger pressure so the grooves and seals can be carefully cleaned of all grit. I’m not taking any chances with this BB !
Properly serviced and maintained, the assembly should last a long, long time.
The overhaul seems to have been successful and the axle turns freely and smoothly, so I know I can continue with the project and not suffer the torture of cotter pins – or wasted time, hopefully !
This one will take a while, as I am going to repaint the frame, and also won’t refit the cheap original drive components ( the cruddy base level Shimano Skylark / T-bird II derailleurs or the heavy steel crank set ).
The frame will suit single speed, as the cable stays were removable fittings rather than braze-ons, leaving the frame lines clean. Also the diagonal rear dropouts are pretty close to 120mm which is track wheel locknut width.
The unbranded headset is rusty, but good internally, so I’m happy to keep it after a clean and tidy-up. Really, the chrome fork crown cover is the detail that could make this bike “sing” visually at least, otherwise it’s a fairly ordinary looking plain-lugged frame.
In the above photo I’ve put the excess new bearings in a jar with a little oil, as ball bearings will rust if left exposed to the air too long – as in the rusty ( very old ) cigarette case.
The refurbished parts go into a container labelled “Sportstar” to keep them together for later on.
I like to string head sets etc. on thin wire to keep them in order too.
The chromed lower forks themselves are cosmetically poor, so I may need to get hold of a new set but this will depend on the wheelset locknut width and I haven’t decided on the wheels yet …
Moving on …
Another fairly simple ( but sometimes fiddly ) job is pedal recycling, and here are some examples of mine. De-rusting metal, cleaning, tyre blacking the rubber platforms, etc. can improve the appearance greatly. The biggest hassle is keeping the bearings together when dismantling, so I use lots of empty cat-food tins !
The MKS rat-traps lower left are smooth and free running in spite of their age. MKS is a brand I can rely on.
I have a problem with “Project Haro BMX” at the moment and that relates to the 1/2″ threaded pedals for the one piece crank.
I will have to find quality replacements that aren’t too expensive. All my pedals are the 9/16″ thread type that most 3-piece cranks have, including my spare Mongoose BMX ones – sigh.
New tyres and grips and a new seat post ( 25.4mm ) were essential purchases. The saddle is recycled. Note – I haven’t height adjusted the post yet !
There’s not too much left to do, but Haro is on the back-burner for now.
See Ya !
