Questions and Answers

What was the condition of the bottom bracket?

The bottom bracket, well, when I got the frame you could only turn the axle half way round, and it was really stiff and grungy. 

So after some research I I felt confident I could take it apart, assess the condition and put it back together.

I was going to have to do that anyway as the seller notified me that when trying to get the chainring and crank off, the cotter pins would not budge and so were angle grinder out.

So the cottered (rather than a square taper) axle needs replacing anyway.

When the right tool was purchased, I got the bracket cups off and could see why the axle was so stiff... The grease was solid, there was loads of dirt and what looked like seeds or small lumps of dirt/soil. 

Because the bottom bracket is not a sealed unit, it’s exposed to the air, so if it’s set for a long time, it will dry up, plus, as in this case, there was no seat post in, so any debris could, and did, fall down the seat tube right onto the axle etc.

While taking it apart, I lost a bearing, but was going to replace them too.

The plan is to buy or fit donor wheels, I am gunning for some road standard 700c wheels, take the cassette off and use a conversion cassette, then get a chainset for the front and then buy the right width axle.


That’s the plan....we shall see...

And the bike is done...

The last few weeks have been a waiting game, the last few items ordered online have taken their time to arrive, the last being the brake cable end stops.  So while I had everything else together, I had no way of using the brakes. Now that it's all together and the first shake down ride complete, I am very pleased with this project.  What do you think? It's been a great project to do over the past three months, i've learnt a lot: Stripping the bike down and removing the paint took longer than I had imagined You use a lot more paint that you think, in fact I would say that I could have done more coats of paint, or been better at those that I applied Finding the right bottom bracket axle, front chainring combination is hard, in fact, I am not entirely satisfied with what I ended up with, but it works The single speed conversion hub is a genius pice of kit! Cyclecross in-line brake levers are no good if you want to have a front and bac...

Primmed and ready for the top coat

Spent the weekend spraying two coats of primer on the bike, I still have a tendency to either spray too quickly and end up covering the garage more than the metalwork, or, spray too slowly and end up with some runs in the paint.  That was easy to resolve with a light wet sanding, but yet to find the balance between the two. I am hoping that for the top coat I won't have this issue, I have found a paint from spray.bike  that sprays on like a powder coat, but dries like a traditional rattle can.  The results I have seen across the internet are impressive, so hoping that this helps with the final finish.  Anyway, here are the results from the primer coat:

Bike No. 2 Finished

That's it, all done.  The original plan was to do the bike up and then sell it on, but that plan has gone to the side.  It will be used by Sophie when she goes to University this September.  It was a fun project, the best bit was actually rebuilding all the components with Sophie.
