Crimping tool?

fcwilt

A "proper set" isn't an option for most hobbyist users. A chinesium set is either not proper or not cheap after all.

As long as I can quickly and easily crimp terminals that are crimpt so the wire break at some arbitrary point and not in the crimp or pulled out then its good enough, fast enough and cheaper than a proper set. It won't be for everyone, thats fine.

Well the IWISS tool I use, and have used for years, is well made and works fine.

It works as well as my old, tired, green enamel Berg crimper from years gone by and that tool was quite pricey.

The IWISS is less expensive than the PA-09 the several mentioned.

So it's not a question of money.

@fcwilt This is the tool I picked up on Amazon a few months past.
It has the proper profile you describe, but I find it sucks at crimping even the dupont connectors it comes with.

I'm trying to find a crimper that:

will strip the wire properly,
will hold the connector securely (this is what this one does not do), and
will actually crimp AWG 28 (this one claims down to AWG 22, but is not that small.

So I look at all this as take the right advice - so following this thread to find the "best" solution.

22-18AWG Dupont Tool

What wires are you trying to crimp with that one? It's a weird range, and suitable for only the beefiest wires normally encountered with Duet electronics. Fans, endstops, thermistors, and usually stepper motor cables are all around 26 AWG.

Come to think of it, I think none of the connections that use dupont crimps (actually molex in our case, but we're not using the branded tools so it's fine) use anything other than 26 AWG and maybe 28 AWG. In my case, the wires I used to extend my stepper motors are larger 24 AWG wires, which is still too small for the range of that tool.

Compare the look of the jaws on that tool with the IWISS.

Your tool does not look right to me. The shapes of the sections that actually do the crimping seem wrong.

And a crimper like this is not going to be used for stripping.

I've had good luck with these:

https://www.amazon.com/HT-5021-Stripper-Cutter-Stripping-0-5-1-6mm/dp/B072XWRG3T/ref=sr_1_2?keywords=HT-5023&qid=1556123151&s=gateway&sr=8-2

Notice they come in three different models depending on the size of wire you need to strip. I use the 5023 for most of my work.

Well call me blind as a bat - I was so busy looking at the tool itself for issues I didn't even notice the listed range of wire sizes was wrong for Duet connectors.

Note to self: never assume.

Thanks.

@fcwilt I have strippers already and I agree the tool head of my crimper does not look right.
As with many here, I have lots of crimping and stripping tools. My favorite striping tool is actually a very old one I got when working with Telco companies in the U.S.

What I'm really seeking is 1 tool that will meet my 3 criteria because as I'm getting older, my eye-site and manual dexterity are getting worse.

This is much like my good-ol' favorite wire stripper: https://www.tenaquip.com/product/klein-tools-compact-wire-strippers-cutters-1003-tj950?gclid=Cj0KCQjwkoDmBRCcARIsAG3xzl-MXiTSYMqHqhu7HroV0T7j5hSn00PgdRmhN2ijze64RkRrIKYkDQcaAqksEALw_wcB
that I can still use for the next couple years at least.

I have bought several different crimp tools in the past and the one I always come back to for dupont or Molex connectors is this one JST Crimp Tool it is a lot cheaper then some of the professional ones I have been issued with at work but they work only failures I have had have been user error. Any manual non ratcheting ones I have had have all gone in the bin (all except one that is but that will go unto 150mm^2 conductor so is a slightly different beast).

I can relate to that.

Which is why one of these has become my constant companion when working on my hobbies:

https://www.amazon.com/Headband-Magnifier-Mounted-Jewelers-Binocular/dp/B073RFZS94/ref=sr_1_6?crid=3ADH9QDLKX8DF&keywords=magnify+headset&qid=1556127197&s=gateway&sprefix=magnify+he%2Caps%2C153&sr=8-6

And I have several of those "plain ole wire strippers" that work fine for me for larger gauge wires.

For for the small stuff as found in the Duet world I find them not very satisfactory, thus the unit that I mentioned which does the small stuff easily.

But I don't think you going to find a good ratcheting crimper that does stripping as well.

As to the unit you have as it was pointed out it is the wrong size for Duet work.

Your unit lists the wire range was 22 to 18 whereas my tool list the range as 28 to 18.

Most of my wiring is 26 or 24.

Perhaps you can return it and get the IWISS.

@fcwilt I use similar.

Yes, I'm aware the wire gauges for thermistors and such are 26AWG (usually) and most other wiring is 24AWG (fans and steppers for example) with the exception of PSU wires.

Too late to return it and it is useful for other things around the house.
What I've settled with (for the interm) is using ferrels with my other crimper designed for them. I even got some ferrels to crimp wires 2 wires together. Works great, but not my end game.
The crimper I bought: https://www.amazon.ca/gp/product/B07M8G5R34/ref=ppx_yo_dt_b_asin_title_o07_s00?ie=UTF8&psc=1

The wire joiners I bought: https://spool3d.ca/ferrules-for-joining-wires-pack-of-10/
I bought 2 packs of these.
This is also where I bought my Duet2 WiFi and PanelDue 7

Raise your hand if it took you half a day because you took great care in every single connector as you did it by hand.

So how do you do the connectors the work with the Duet board?

I'm using this one from hobbyking. Its designed for JST SH connectors but works really well on the terminals supplied with the Duet boards.

https://hobbyking.com/en_us/hobbyking-jst-sh-connector-crimping-tool.html

Its also the right price.

You may want to save for this advanced model of your striper. It has a wire gauge dial which you can quickly change, no tools necessary.

Hi,

If you have deepish pockets and a lot of wire to strip here is a very effective but expensive stripper with a accurate wire size adjustment and a nice, stable strip length gauge.

They work well.

This one for example doesn't need adjustment and will never nick the wires https://www.amazon.com/Teledyne-Thermal-Stripper-Without-Temperature/dp/B00DNQHBCS

It also works well for hard to strip insulations such as teflon.

Well, if there was ever a tool that begged for a Chinesium knock off, that one sure fits the bill!

A bit of looking around found this:
https://smile.amazon.com/PATCO-Thermal-Wire-Stripper-PTS-10/dp/B00R3R86JU

a bit less coin of the realm... With of course a downgrade in quality. Seems a great Instructables project for someone.

@deckingman - I'm with ya!! You made me LMAO. I can do flat plaster, but when it comes to corners - looks like a three year old with palsey did it, and the more I try to fix it the worse it gets.

If I need to crimp a plug with more than 4 wires I'll get three perfect, after much effort, then mangle the fourth, which of course make it too short now, so I have to settle for an uneven looking job or let my OCD take over and redo the d*mn thing.

@fcwilt Sorry for the late reply. My son got married over the weekend.

Using the ferrals on the Duet2 WiFi board, they all work great. I crimp the ferrals 3 times to ensure they get a very small inside diameter and they fit nice and tight over the posts. I can actually pick up the board by grabbing any single wire and they do not come loose or come off.
Given this, however, it is still a temporary job so I'm only doing this until I get the exact right solution with better JST crimpers.

As for the ferrals going into the green blocks, same thing, but I also flatten those a bit then let the clamps squeeze them down.

Thanks for the feedback. I never imagined pushing the ferrules onto the pins.

In any case I'm pretty sure the Duet connectors are Molex:
