https://stream.echo6.co/videos/watch/1a583d3a-de56-4150-ae40-63f9c3771e91 I'm not used to using the single position crimp tools, so I made a rookie mistake. I was using the correct size jaw to crimp the wire section, but then incorrectly using the next size up to crimp the insulation. In reality I should have been using the same size jaw for both. After I'd made the video I applied several of each crimp with the basic iWiss tool using the same (1.6mm) jaw and it did a perfect job of them all. It appears that the Dupont style connector termination tools actually curve the insulation grip around it, but don't bite into it. There's a very thorough guide to crimps and tools here:- http://tech.mattmillman.com/info/crimpconnectors/ A search on eBay shows that Iwiss seem to do mainly crimping tools. If you search for the keyword Iwiss and lowest price first you'll find the IWS-2820 (28-20AWG) in the results. https://www.ebay.com/sch/i.html?_from=R40&_nkw=iwiss&_sacat=0&_sop=15 If you enjoy these videos you can help support the channel with a dollar for coffee, cookies and random gadgets for disassembly at:- http://www.bigclive.com/coffee.htm This also keeps the channel independent of YouTube's advertising algorithms allowing it to be a bit more dangerous and naughty.
