[NSRCA-discussion] Servo connector crimping tool?

Wed May 20 13:59:26 AKDT 2015

If the Hansen crimping tool only had one die, then you could crimp all three without removing them from the header pins.  I’ve thought about modifying my tool for just that purpose . . . (looks sideways at milling machine . . )

Ron,

Excelente idea. Thanks,

Another trick is to put three of the female pins on 0.1" "header pins"
before crimping.  That aligns them perfectly for later insertion into the
plastic housing.

I prefer the Radical RC pins because they seem to have a little more gold
plating on them than the others, though still not as much as Futaba and JR.
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.

I don't like the plastic connector housings from Hansen because the little
arms in the housing that hold the pins in are real short compared to the OEM
stuff and look suspect to me. The Radical housings match the OEM stuff.

I've been making my own extensions for 15 or 20 years now. The biggest
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 move t  he pin further into the side of the jaw about 1/8" and
squeeze the handle 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.

Pretty sure my crimper is the cheap one since there were no options back
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.

Having done a lot of these, crimping your own wires is a PITA, even with 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.

I've found no difference in the quality of pins and wire between what
HobbyKing sells, and what MPI and Radical RC sell. Price is certainly right
at HobbyKing.
