Back to track, complete brompton maintenance

[cwah]

Ok, I'm ready for the complete maintenance now

 

[cwah]

I'm working on the rear wheel now. I managed to replace the damaged rim with a new one. It wasn't too bad.

For some reason, I discovered a bike shop in paris and wanted to cycle there in order to see what they can do for me.

Big mistake, cycling without truing the wheel before hand has created a bent spoke

I discovered the zip tie to true wheel, it really make it easy:

I managed without too much problem to have lateral trueness. But my wheel isn't round at all. I tried to tighten the spokes in areas not round but doesn't seem to make any change...

any idea?

It's not a mile out.
Before you tighten the furthest out ones, you must slacken off the ones that are too close. Just a half-turn at a time will do.

Thanks Scimitar.

Also, I didn't know the spoke on the gear side were longer than on the other side. I did a mismatch and had to un-lace the wheel to put everything back in place.

Now it's so much better

Started to paint all area subject to rust:

Any idea how to have a smoother paint? There are a lot of paint brush mark on it.. I suppose it needs sanding...

Wondering if I shall also paint the chainset and the chain so no more rust?

 

[cwah]

I started to use sanding paper in order to have better finish:

But when I started to use it, it seems to remove all the paint and finish isn't really nice???

Is it not the way to have good paint finish???

DONT paint the chain or the main chain ring!

I was about to paint the chain and crankset. Then put some grease on it so it's protected against rust... why not

It's impossible to get a good paint finish with some paints. The ones that prevent rust are the worse, and those that give a good finish are not very durable unless you want to use two-pack paints, which bring new problems. whatever paints you use, you shouldn't rub them down until it's properly hardened, which can take weeks.

 

[cwah]

Thanks Dave. I'm going to wait for 2 weeks before doing sanding on it then... I was too fast trying to do it 24 hours after it dried

chain has finally been cleaned and greased:

Although the mudguard is rubbing against the tyre so I need to bolt it against the brompton rack to prevent that:

 

[cwah]

Now I need to sort out my battery fitting in my bag:

Because the pack is now smaller, it doesn't stretch that much the bag and it's wobbling a bit inside. I need something to clamp it against the bag.

The bag should almost weight 15kg with controller and kryptonite lock:

It doesn't feel so stable and move a bit. Can I leave it like this?

 

[cwah]

My rear mudguard is rubbing against the tyre. I need to lift it a bit and I was thinking of "stapling" a small aluminium sheet to it similar to here:

I'd like to bolt it against the rear rack:

Any idea how I can do that and keep it lightweight at the same time?

Thanks

 

[jerrysimon]

Looking much tidier cwah.

I would make a small bracket out of 1-2mm thick aluminum sheet and then rivet it to the mud guard. Or just find a generic bracket.

Jerry

 

[cwah]

I've never used rivet before. What punch holes and rivet should I get? sorry for these newbies questions

 

[cwah]

I decided to cut 2 small holes on the mudguard, and to lift it up via black tie:

It should help to keep it light. I hope it's going to work when I'll try it tomorrow.

I've also moved the kryptonite lock on the seat area to lighten my front bag:

 

[jerrysimon]

Does the job

Jerry

 

[cwah]

My front bag frame has been weakened due to the bag weight. It has cracks on the plastic now:

The bag wobble around when moving the handlebar left to right:

I'm thinking to completely glue the frame to the front carrier bloc. Because I don't have the tools (or the cash) to CNC a new casing to replace the carrier.

What do you think? I'm going to do that tonight

 

[cwah]

Ok, I've put epoxy on it. Let see how it goes tomorrow..
