I've been struggling with soldering some very small stranded copper wires together. The wires are very high gauge (seems like 26awg) and there's maybe only 10 or so thin strands. After stripping the wires and attempting to twist them together, and try to solder them. However, I can't twist them together tightly enough for a good joint. And the wires end up with a sizeable gap in the twists that gets filled in with solder. It works, but it makes this huge lump in the wire and I imagine it's not a very strong joint either.
I have some of those "heat shrink with some low temp solder in them" butt connectors on the way, but I feel like there has to be a better technique. Can you provide some great ideas?

Thanks for sharing, Alex, do you have photos about it?
Not good ones sadly, I tend to tape over the wires any time I do this just to prevent shorts. I will say it did work well when I needed to mod a USB C cable to make a QFIL cable for android development, basically cut the USB cable, then splice it back together so you can make a connection between a couple of the wires. Still works as a USB cable. The trick is to use very very little solder when you first tin it, then twist them together and melt it, and possible add a little more.
Great, thanks for your tips.
this is a good idea, I do this with thin wires
Great! Thanks!
Wow, I'll have a try, thank you.
