Cheers for that Old Crow.. that sounds to make sense and contributing to the body of opinion that says even though my practice sessions using multi core tin/lead solder have been partially successful, it would do no harm to get some flux. Talking of which, I'm still not certain where to buy it (other than online sources).
I failed to get any after a visit to Tolworth Showtrain. Is liquid flux normally carried by the Wickeses and B&Qs of the world or is it an electronics shop I need?

Flux from the DIY sheds is likely to be for plumbing purposes, and is likely to be corrosive. There are quite a lot of suppliers on Amazon for not much money. If it states rosin it should be fine.

Thanks for that jthjth. Avoiding the corrosive variety seems key. Are fluxes  usually pastes or is there a genuinely liquid one- and any advantage either way?

I doubt really matters, paste or liquid. Either way, you need very little of it - flux is just a surface treatment. Try not to inhale the fumes.

Generally I use Fry Powerflow paste which is actually for lead-free, though I avoid lead-free solder as it's not friendly to use.   I have a small 50g pot which has lasted for several years. It seems difficult to find the 50g pots at the moment, but the 100g pots are readily available.

I also have a flux pen which dispenses liquid flux and can by handy for pcb work.

I've just read this from beginning to end and found it extremely useful - I've certainly learned a few things where I have been going wrong. Mods - may I suggest this is moved into Tutorials? It deserves to be easily available.

Cheers,

Chris
