UK Crimp once, crimp twice, think bike...

[John-]

Hi

Yea, showing my age now... I purchased an SWA crimping tool for plus 10mm cables.

Wasn't sure how many times to apply the tool to lugs and through crimps. Checked with SWA and they said, after a bit of searching, ‘once is enough, but if space, twice.’

How many times do you crimp? Since the advent of the ratchet crimper, i have only ever applied once, even to through crimps.

Cheers

John

I have the SWA-band crimp tool (big handles that close fully, not ratchet style) that does the hex style of crimp on the lugs. Generally I always try to get 2 crimps on to them, one as far as the lip allows the tool to sit, 2nd just above that.

I don't know if it is needed or not, but to me it just makes sense to have as much tight contact points as it can sensibly support.

What does the instructions tell you to do?

surely once is enough, or they’re make the jaws bigger to do it all at once.

No instructions, hence why i called them for the ‘official’ word. ‘Twice If you can’.

I think you might be using the same hexagon tool as me:
150mm² ratchet crimp tool at SWA
Although I think my one predates SWA selling it themselves. One crimp should be sufficient but if the terminal is long enough I'll use two. I try to avoid crimping the very end of the tube so that there is a fairlead for the strands, also any part of the socket that is not filled with cable as this can distort the rest of the terminal.

I also use an indent crimp tool for special situations as outlined by Darkwood in the other thread, where the hex die doesn't match the terminal / cable complement correctly.

if the crimp tool ain't good enough a hammer will fix.

2 hammers, tel? One to use as an anvil. The other for striking
