Any question answered...

The bearing should sit right on there but you need to make sure that the angle of the bearing seat is the same as that on the fork. It's probably 45 degrees but just double check, otherwise only the edge of the bearing will sit on the carbon and won't spread the load, potentially leading to damage.
Whereas previously the angle on the crown race would match the headset because it came with it. Now you have to match the lower bearing to your frame and fork specifically

Ok, great, cheers for the help.

Now to grapple with the fact that all the likely candidates I can find for new headsets that are actually in stock are all on bike24 and they don’t deliver to the UK anymore.

Try Bike Rehab on Wellington Street.

I have lots of cables (ethernet, HDMI, USB, extension leads, chargers, etc). What's a neat way of organising so I don't spend ages searching for stuff but they're also hidden away? Drawers just seem to result in a tangled mess, even if I coil them up first.

You can avoid entanglement by putting each cable in its own zip lock bag, but otherwise just stick with the drawer; the fact that you want them hidden away shows that you don't need to get at them frequently.

Oh sweet, local knowledge. Will do, cheers!

I take it you know the old coil the wire up and wrap the last coil round and round the coil itself trick. Usually stops it coming undone or tangling up with all the other ones. Or a quick wrap of electrical tape at the end, but it goes sticky quite quickly.

Install a shelf bracket or similar in a tall cupboard and drape them over it. Align all of the interesting ends with each other (usually the device end of USB) so you can pick the one you want easily.

Personally I've removed my bedroom door and hang all my cables down from the frame like a bead curtain

dude, have you seen these little velcro loop thingies? they gonna
blow
your
mind

have you seen these little velcro loop thingies?

Yeah, but where can you even get them? Except with every fucking cable you ever buy.

I do have a lot of velcro loop thingies and zip ties. The shelf bracket is a possible but I think the bead curtain could be a winner, we're actually missing a kitchen door so killing two birds with one stone.

What's the name of the thin & transparent plastic gear cable outer that's sometimes used for internal frame routing & where can I buy some?

Liner, I think.
Can't help with where to get it separate from the inner & outer though, I've only ever got it as part of a kit.

Brilliant, that's it. Thank you. There's some Jagwire liner for sale on eBay.

Do you think the Unsolicited Goods and Services regulations apply to the near £2000 folding Samsung phone delivered to me by O2 on behalf of credit card fraudsters last Friday, that they haven’t contacted me about to retrieve yet? :)

near £2000

The value is irrelevant, although it will have no practical value once the supplier knows it has gone astray. You can come to your own conclusion about whether it's really unsolicited goods within the meaning of the act, but by posting here you have already stated that you don't have a good faith belief that it is covered.

Sadly not

Boo!

I just want it gone and I emailed them on the day it arrived and shady scammer tried to retrieve it. Sent them a chaser today.

If you want to know when you can toss it in the trash, you need to have given them an explicit deadline to collect it. 14 days is traditional.

Has anyone used these cheap vcr to digital/pc out converters that are on amazon? Got some ancient home videos.

Hard to tell if they're any good with all the fake reviews

They are generally good enought for tapes, as tapes go.

Thanks covid, at least I'm not being pressured to go see live theatre.
