[NSRCA-discussion] Servo connector crimping tool?

Wed May 20 14:41:24 AKDT 2015

Here's a video from Hansen Hobby.
https://www.youtube.com/watch?v=Vptd2n5p5-I

The demo shows the crimper jumping around a bit as the wire is attempting to
be inserted.
Note how the pin is pre-loaded with the crimper to avoid the pin turning
sideways.
Verne's advice about putting the lower crimper jaw into a vise is a must.
Otherwise....looks good to me although I likely would have a slightly longer
separation of the 3 wires....and use gold pins.
Reminds me of my ATT and NORTEL days....jeeeze...long ago...far away.

The Hansen pins are a close second IMO. The rest of the stuff out there has
almost no gold plating at all. That was this year at Toledo. Next year may
be different. All depends on where the merchants are getting the stuff they
sell.

single trick I've found for good consistent results is to clamp the bottom
jaw of the crimping tool in a vise so I don't have to hold the crimper while
I'm lining things up. I strip about 3/16" off each wire and twist them. Then
I feed the wire I'm going to crimp into the side of the crimper until the
insulation is up against the step inside the jaw of the crimper. You can
feel the insulation hit the edge of the step. I hold that in place with my
left hand and place the pin over the top of the wire with my right hand and
push it in place with the end of the pin that goes over the insulation even
with the open side of the tool. The tension of the jaws of the pin that goes
over the insulation will keep it in place in the crimper. Then while still
holding the wire against the step with my left hand, I use my right hand to
squeeze the handle of the tool which still has the bottom jaw clamped in the
vise. Then I mov

again. Finally, I move the wire out so the crimp over the insulation is
sticking out over the outside of the tool about 1/8". The real trick to the
whole process is clamping the bottom jaw in a vise. None of the above
process will make sense unless you've actually made an extension.

when I got mine. If I were going to buy one now, I'd probably get the
Hansen. FWIW, with the process I just described, I almost never ruin a
crimp. Again, the real trick is to clamp the bottom jaw of the crimper in a
vise to free up your hands.

a decent tool.  Unless you do it regularly, you can expect to mess up more
than a few crimps as you relearn how to do it each time. Practice is key,
and buy a lot more pins than what you think you will need. The pins are
small, easily bent, and hard to line up properly in the tool. I've used both
a cheap tool, and a "high quality" tool with little difference in the
results.

at HobbyKing.
