No, he means that you should direct your instructions to the DIYer who is the author of this topic.

go on, the floor is yours.

You mean you are an electrician and don't know how to solder?

Winston. I do know how to solder but it is the OP who is asking for help and advice.

I also know the problems that can arise when soldering PVC insulated conductors, you need to point those out if you are recommending the OP to solder the conductors.

 

[Sureitsoff?]

at this rate the op will end up using choc block and tape...........

dazzler9000 do you know how to solder?

Actually, choc block would be fine in this situation. But not the tape ………

Seen too many solid cores working loose in crimps to distrust them

That's down to improperly sized crimps, incorrect tool or poor quality materials - A solid core will behave no differently to a stranded cable if the crimp is the same size. In the process of crimping there should be no air gaps.

If you're finding a stranded core is behaving differently to a solid core conductor, then the stranded core is likely to have been pinched and is not mechanically sound anyway.

Yes, I can solder. Cheers for the input everyone, didn't mean to start a squabble between you all

Yes, but that's all most people will have.

It will in the rubbish oversized squash-flat crimps most people will buy.

In my opinion the best way is to solder the extension and cover with self amalgamating tape.

Any useful tips you can give on this process to give a strong, reliable joint?

Whilst I have no doubt that the op can solder, I wouldn't want him to do it one way, only to discover there is a better way.

 

[winston1]

The OP has said he knows how to solder.

 

[sparkwright]

Yep.

 

[bernardgreen]

a squabble between you all

You didn't start it.

There are good soldered joints and bad ones.

Which method are you suggesting is used?

Most people who offer information like that that would be happy to go on to describe how to do the job.

[Waits for explanation]

 

[winston1]

I'm suggesting a good soldered joint, no ta bad one. The OP has said he knows how to solder. I've no intension of teaching my grandmother how to suck eggs.
