P-38 build

[UpWrong]

4Nm was ok, tried 6Nm and it wouldn't tighten. Taking the bolt out, some thread came out with it. Oh no! I've put in a longer bolt and have managed to tighten it to 6Nm but it's going to be a worry.

What's the material? And are you already familiar with threaded inserts?

I've removed the caliper and there's a shiny metal cylinder now projecting from the post mount by 2mm. I put a magnet on it and it sticks a little - stainless steel? I can see it's inserted into a hexagonal nut of sorts. So it's some kind of insert. Can it be replaced? How can it be removed? Does it just pull out?

Photo, please.

And I'd ask the builder what it is.

Jonathan

PS: Some stainless steel is magnetic, but much of what's used in this sort of work isn't.

Sorry, bad photos under artificial light. You can see the proud cylindrical bit seated in a hexagonal nut which hasn't moved. i wonder if it's a press fit and the tightening torque has pulled it out of its seating into the caliper ovalised hole (ovalised to allow lateral adjustment. The thread in the insert looks fine. Maybe the insert just got pulled out into the caliper bolt space. It wouldn't have been pulled out if the caliper bolt space was small and round. The problem was it was large enough to accommodate the insert. Guess I need to email Lightening to see if anything can be done.

Some better photos. I think the bolt and the caliper acted as a puller and tightening the caliper bolt pulled the insert out. I only had the torque spanner set at 6Nm:

I don't recognise the insert, and that's what I'd do.

Yes, shall do. The thread still looks good. I think when it was turning but not tightening it was getting pulled out into the calliper.

[UpWrong]

Lightning say they haven't seen it happen before. They think the bolt pulled the insert into the caliper slot. The Tektro Aquila is unusual in having such a big slot I think - not a good choice here. If I return the fork they will repair or replace it.

[Jdsk]

Thanks for the update.

Hope that doesn't take too long.

Ooof. Good luck returning fork for repair / replacement

Thanks. I'm still anxious of delays or others problems that might happen in sending it back. The cost isn't too bad, about £31 with insurance using UPS. They are the company who brought the frameset over, so should be able to handle the return. I'll have to be careful with the customs declaration so it doen't get held with a demand for payment. Something like, "return of bicycle fork for repair" I guess so that they know what it is and no tariffs are applicable.

I have a 20" drum brake wheel on order from SJS anyway. I'm not the biggest fan of disk brakes, and would like to have one as an option. They work well in small wheels.

Anyhow, riser cut and slotted on the other side:

Can I ask which way round you have the seat foam?

[UpWrong]

Can I ask which way round you have the seat foam?

I changed it to the thin edge at the front and thick at the back. It levelled the seat a bit and made it easier to reach the ground. You have it the other way?

Yes. With the way round you have it I found it made me slide forward a bit. Plus with thick at front the rounded part matches the frame. So I think thick forward is the way it’s meant to be.

I'll be trying it both ways, when I get the bike on the road. I agree, the way you have it is probably the intended orientation.

I have the fork boxed up to go, postage paid with UPS. There's no weekend collection anyway so shall drop it off first thing monday.

The UPS site was easy to use until I got to the pop up window asking me to print the shipping label, the commercial invoice/customs declaration and the receipt. No problem with the first and last but the commercial invoice print screen gave me a blank document. I think this is because it's a returns shipment so not a commercial transaction but I would still have expected a customs declaration. UPS support is only open Mon-Fri.

I have hedged my bets by using a Royal Mail CN22A form to declare the contents, "returns" status, and my details, and stuck that on the box. I found a blank UPS commercial invoice form which is rather fearsome wanting tariff codes etc. I'm pretty sure I'm covered but I guess I could ring UPS on Monday just to be sure I'm not missing a document. More time wasted
