I only brought this odd off cut of cable back with me to try and get the thing to work; I'll get back to my welders when more lugs turn up and will bear your advice in mind when I'm trying it again.
I think I have a spare copper cone or two from a Dinse connection I'm not using I could use to help fill up the lug if need be or will double the wire over as suggested previously. Only have a couple of un-used lugs of each size left now, so will save those for when I get back to the garage and can test it on the correct cable.
Thanks again.

The stripped core should fit snugly in the lug, with a decent lug even twisting the core strands will make it too big to fit

I just checked the right size cable against the lug and there isn't a mm of space left.

Die`s virtually touch.

Washing up liquid will do at a push too. Once it dries a little, it goes slightly sticky, but not as much as the Hellerine lube which dries like glue when it goes off.
Never heard of those hellerman things I was planning on using regular heat shrink?
Part of the problem my be the lugs I am using; can anyone recommend a reliable supplier? I would benefit from 10mm squared and 25mm squared. Have some on order, but there more the same of what I've been trying.
Thanks.

Regular heat shrink is fine if you have it.
Didn't know if the likes of Toolstation would handle the amps; although suppose you could easily say the same about anything bought off of Ebay. Happy to be a fan of Toolstation and have one locally; so I'd consider that a win.
Thanks.

I have found that crimp terminals can vary considerably in their specified size, especially those purchased cheap off ebay. Quality brands seem to be more accurate.
Likewise there is a lot of Chinese special cable which is nowhere near the size printed on the jacket.
As has been suggested choose the one that just barely fits over the wire and don't worry too much about the numbers.
With the hex crimps you want to see a nice defined hexagonal crimp mark, if there is any "flashing" sticking out the die size is too small, if you don't see defined "points" on your crimp the die is too big.

Good tips to remember. I've ordered a pack of crimps from Toolstation, will see how they compare to the Ebay ones I've been practicing with.
There are hundreds of proper electrical wholesalers around e.g WF, CEF, edmonson, enfield, and lots of established independent shops. They may well even be next door or on the same industrial estate to the toolstation or screwfix.
Go to one of these and get some proper lugs, take your own cable even to make sure they are the right size.
How many crimps do you need to do?
Using the right tool, correct sized lug and cable is pretty fundamental to the job. Depending on the application the consequences of a bad crimp could be anywhere between mildly-inconvenient through expensive to lethally dangerous!
Good luck
Phil

A quick read says that the OP has fallen into the pit off crimps sizes.
I use/used a RS Hydo crimper for battery back up systems.
As said the range and markings varrey.
Also it looks like when the cable is crimped the final hole is distorted.
Simple way to ensure the dies are lined up. Is to close to jaws and make sure the lower faces line up. If not turn one die arround. That should cure that issue.
When the OP is happy with the crimper and has selected the correct crimp.
Oh the joys of that.
Simple way to test the crimp size.
Strip the insulation back.
Line up cable and push in, giving the crimp a 1/4 twist. Gentle pressure is all is needed. Any more the crimp is to small. Any less it is to big.
If correct, trim the cable so when fitted the cable is bottom out. The insulation is against the end of the crimp.
Then crimp. As the OP has found out the dies and cable size is a mine field.
Get some spares, a decent electrical supplier is proberly the cheapist.
They should match the cable to the crimps.
Then crimp.
Seal with a rubber seal, heat shrink or tape.
It is easy when you get to play enough.
One more tip.
When crimping. Hold the cable and crimper in line.

got one of these , it works fine but as the others say the wire strands need to totaly fill the crimp before crimping, seems its easier said than done to get cable and ends that suit each other
