Any question answered...

Thanks for your response.

@ColinTheBald- despite your official sounding title, I think caustic soda is unsafe to consume as a beverage, no matter one’s political affiliations, but thanks.

That looks decent! Cheers.

OK, thats deffo bigger than I was hoping.
@JurekB Ive read they can be quite underwhelming or at least over anticapated to be amazing wonder cleaners but I'm still quite interested.

I really just want to know that my bike, and subsequent bikes and bits I am going to end up with, are clean af like new, better maybe. Obviously its the lubrication and maintenace after a clean that matters but yeah.
Its not really needed, don't race or own a shop or owt but really I have never had a super clean or new bike ever cos I always build off eBay.

3-5 litres is about the smallest you might want for cleaning chainrings

Actually, the smallest capacity I could find which had enough internal dimension to fully sink a 53T chainring (222mm OD) is a 32 litre model costing nearly €2000

if I put a container with liquid to float in an ultrasonic cleaner, will the cavitation effect still happen inside the container?

Transmission of the vibration depends on the container material. Low hysteresis is good, so metal and glass work OK. The smaller the difference in acoustic impedance between the liquid and the container material, the better the coupling efficiency. Polythene might work quite well, the coupling is good and the very thin layer should minimise the....TL;DR, just fucking googled it and people offer polythene bags specifically for ultrasonic cleaning, so yes, polythene bags work, but I wouldn't expect much effect above the fluid level in the primary bath.

I wouldn't bother. At one point I spent eons of time making sure the bike was surgically clean.
Much more effective than using an ultrasound cleaner.

Do Halfords stock a wide range of spray paints these days?

Yes, but it's pretty rubbish paint.

Buntlack are good quality (acrylic) paints albeit not in a huge range of colours.
London Graphics in Covent Garden stock them.

Found a B&M next to a Halfords, between them I managed to get what I wanted

Wow. I figured a cleaner with enough space to submerge 50% of the chainring would suffice, although finding one the correct proportions might be a faff and it would take 2x as long of course.

This 10L would fit that chainring, just not all of it at once. I expect you have different user requirements to most.

Any idea how to add a "Sign up to our newsletter" pop up on a wordpress website that feeds into MailChimp?

you can build the popup on Mailchimp?

If you had approx 20 pounds to spend at the bolts 'n' nuts store and you wanted to buy a selection of fixings to give yourself the best chance of having suitable fixings for random bike bodging/building tasks, what would you order?

A bunch of 4 and 5mm bolts in different lengths

SJS “workshop sweepings”?

^^ Ditto. Mainly Allen button head bolts, if they’re not more expensive, since cap heads sometimes are too tall. Maybe a couple countersunk heads if you have hydro brakes. Also a couple 4 and 5mm nuts, ideally nylock, and a couple washers too.

Wow how did I not know about this. Immense. Will def throw some in next order I do.

Thanks others for the answers. And I'm right thinking stainless steel is the go to material for bolts?

I actually hate (not literally) Allen key button head bolts. Especially when combined with threadlock 😆. I’d recommend Torx for buttons. And anything that requires a smaller than 4mm Allen key should be torx too.

I’d say mostly you want 10-15mm screws. Then a handful that are longer. Also a few m6 screws too of varying length.

Washers for all the sizes you need, Stand off spacers are often helpful, and a bunch of nyloc nuts too. And loctite if you haven’t got it already.

And I'm right thinking stainless steel is the go to material for bolts?

Depends on how angry you want to be at them in the future. If you think you’ll need a couple goddamn stupid seized bolts to vent against one day, throw some carbon steel ones in.

I'm right thinking stainless steel is the go to material for bolts?

Depends. It can be problematic in contact with aluminium under salt spray conditions, i.e. any 4-season bike in the UK and turbo mules everywhere.

I’d recommend Torx for buttons

I’d recommend Torx for everything.

Thanks. It was the shit about getting the code into wordpress I couldn't figure out but got it now and managed to use the MailChimp popup

This.

Personal finance app?

Anyone found one they like and can share with someone so both can input. Looking to move away from excel.

Any suggestions for somewhere near Shoreditch high Street that'll sell me a v brake noodle? I don't really know the area well at all.
