Default Crimp tool - am I doing something wrong?

Hey guys, I am using a crimper for the first time, but it doesn't seem to be curling the wings for the insulation grip very well. Am I doing something wrong? This crimper was purchased from an online store that custom-mills it to be able to handle 16AWG wire.

Half of the time the insulation grip crimp breaks off, or has a strange sharp edge to it (one side is better than the other).

I have crimpers from MDPC and a 3 head from moddiy they both work well although I definately prefer the 3 head from Moddiy . I ran into the same problem with some pins and what I found was that the insulation wings on some makes of pins were too long. What I did was cut about 1/32 off each wing depending on the wire size I was using and that corrected my problem, perfect crimps after that discovery

Are they Lutro0 modified crimpers? It is really hard to see the crimp in the video. Can you post a picture of how the crimp is seated in the crimper prior to crimping and a picture of a crimp after it is crimped on a cable?

@lowfat, yes it's the LC crimp tool. He recommended that I shift the bottom die, but I didn't have any luck last night.

As you can see from the pics, it's not curling it well even with the terminal alone. I'll try to take a pic of the terminal in the tool, it'll have to be at one ratchet click since I only have two hands

You have the same problem I had , it looks like the terminal twists just a little in the crimper , try trimming the insulation wings just a little bit and I'll bet it works just fine for you . Or buy teminals with the shorter wings . That length of wings would be fine for a double wire crimp but too long for a single wire , as you can see in the pics they are curling right around in a circle .

Thanks, I'll try trimming the wings tonight after trying to shift the die again. I took a series of pics to show the seller the alignment of the die, but I am thinking it has something to do with the shape of the curve in the custom milling.

That'll teach me to overkill and use 16AWG. I was modding some server PSUs for cheap powa and now I know it's wayy to thick. Only managed to stuff in enough wires for one pair of GPU connectors :( Next order will be 18AWG.

Really have to recommend the tool from Daz. will do 16AWG if you're careful.

Do you have a Princess Auto nearby? Their 18AWG wire is perfect. $14-$16 for 100 feet IIRC.

They told me they'll ship me another bottom die, hopefully it will work much better.

There is a Princess Auto about 20km from me, I'll have to stop in and buy some cheaper wire!

I ended up doing a bit of research and it is said that 18AWG can handle 12V 30A @ 3 FEET, so I ended up splicing my 16AWG wires into a Y just a few inches past the connection to the PSU.
Now powering a quad-GPU rig with a Seasonic X660 and a free 650W 80Plus Gold screaming server PSU :D
