Reached the limit of my brompton..

[Old_Dave]

Please don't use the glue... It will only make the situation worse (that's if it can get any worser)

Already put the glue.. this one has always been reliable. I'll test it initially to see if it can handle the weight. I've put load of glue, so better test it and see how it goes

Hi Cwah if you can't fix it and you don't want I will make the sacrifice and have it off you. but sadly as you know I don't do money.

 

[cwah]

Thanks a lot John, and also Dave.

I'll definitely consider what you propose.

But I'm a big guy now. I want to be able to fix it on my own. will try it first by myself.

This morning the glue seems ok. Wait and pray!!!

Cheers and thaaaanks again

Just thought if the block still fixes on with one screw top or bottom ?

then this is what I did on another bike.

The magic of a jubilee clips

[cwah]

yeah the bloc still fit with 1 screw. But I think it's better to have something strong rather than a clip. I have a quite heavy bag (14 kg).

For those interested, here's the amount of damage I unfortunately did:

Glue is doesn't work at all... What I have is way too heavy.

Have to go to a local car shop and see what they say

 

[jerrysimon]

I think 14kg exceeds the block carrying weight anyway which is why it might have failed.

The set up with the jubilee clips shown is actually stronger than the Brompton setup and I often carry shopping which exceeds over 10kg of weight.

Thanks Jerry.

s this jubilee clip a commercial product or a DIY stuff you made? If it can handle the weight, it greatly interest me

ps: looking at it again, it seems very DIY. So you basically drilled a flat hole in order to put the jubilee clip?
It would probably make sense for me to drill 2 flat hole and put 2 additional clip.

What did you use to drill such a hole?


And can I use this type of clip?

Thanks Jerry

 

[Old_Dave]

The clips are a commercial product..however not all clips are equal, lol

Some are good quality whilst others are about as much use as rusty string, I'd recommend looking on line for ones made from stainless steel.

Fairly sure Brompton specify 10kg for the front luggage block.

The fixings can work loose, letting the bag bounce on them as you ride along which soon ruins the threads.

Too late for the OP, but the moral is regularly check the block fixings for tightness.

Yep I do that

I actually made a slot through the block center (drilled two holes then filed them out to a slot) which I feed the clip through as shown on the bike above. I am not sure if that will work with the Brompton as it will be dependent on the space on the frame to then put the jubilee clip round. I covered mine in wp tape. The slot in the block needs to be in front of the flat plate where the original screws sit.

I also have jubilee clip at the bottom to support the weight and on the top which is probably over kill. You wouldn't need those though as it would sit on the metal frame lug and one of the screws would be secured.

Here is a cheap solution.Car exhaust clamps. Available from motor factors or exhaust merchants. They consist of a U bolt with a bridging plate, and nuts and washers. Choose a size that is a good fit on the headstock tube. It wants to be tight, but not tight enough to distort the tube. For about a quid, that will give you a fixing that is strong enough to jump up and down on. You will need to fabricate a simple bracket to hold the bag.

 

[jerrysimon]

Whilst they would be a good solution for many generic bikes there just would just not be sufficient clearance on the Brompton frame for those, I doubt the JC will even fit either.

Jerry, in the photos I've just looks at it looks like there's plenty of room.

Cwah, didn't we discuss this method with U-bolts before on ES.? Two exhaust clamps and an aluminium platem then you can fix anything to it.

 

[cwah]

Hmm.. I don't remember discussing that.. Or maybe we did? It was maybe for my project to create a quick release bag?

Anyway, I need something quickly as the direct drive motor is something like 30% less efficient than my geared motor.

What about this stainless exhaust clamp?
55 - 59mm - 2 1/4 Stainless Exhaust Clamps: Amazon.co.uk: Car & Motorbike

But how do I fix a plate on it?

 

[Old_Dave]

With that round shape you don't need a plate, but you also don't need that clamp @ that price !!

@cwah. That is the wrong type of clamp. As an example, see Ebay item number 170934287205, but note that you need one of the right size. Then, to fix a plate, drill 2 holes in the plate the same distance apart as the 2 ends of the U bolt . Now bend a 90 degree flange on the plate, and slip it onto the arms of the Ubolt before fitting the nuts. Job done, and suddenly you become the nephew of Robert. The plate needs to be thick enough to resist bending.

 

[Old_Dave]

Just looked on eBay

Make loads of stainless clips any size you like, cheap as chips.. Lol
