I'd like to make up some jumpers with duPont connectors. I have neither a standard tool made for these nor the connector pins/shells to experiment with. I do have this ancient AMP tool that looks like the 'A' jaws might work. A websearch did not turn up anything like specs. saying it'll do this or that connector, too out of date I suppose. I'm not starting a production line, it's just a handful for a project.
So, can I use this and avoid the bother and $$ of buying new?
Those will probably work.
You will have to crimp the connector using a two step process, nothing wrong with doing so.
I have a similar AMP tool and it is too large. You might just take a pin out of its housing and lay it in the "A" slot and see what it looks like.
Personally I've given up on crimping my own dupont pins. It can be done but its a PIA. I just buy long jumpers of various ends (male & female) and use them, cutting the wire if I need to.

Wire and insulation, I presume. Thanks.
As an aside, in my search I found a 'new in the box' set on Ebay. $50 
!!
“Wire and insulation, I presume. ”
Yes.
I have a crimper like yours, and one like this, both work well.
BTW
after learning how to crimp dupont terminals properly, you will never buy a pre-made wire again.
However, it is a skill that needs practise.

I just did that. If anything the 'A' slot looks on the small side. There may be some destructive testing ahead.

I know. Tiny things and older eyes don't go well together. :-[

That's what I plan for the ones to be cut off and soldered on one end. I wouldn't bother with this but, for the rest I need some down to an inch and some Y's, none will be over four inches. I know I could splice the Ys with solder but then there's a stiff section and fussing with shrink tube and I want the flexibility since they'll be in a small enclosure.

I've done hundreds of these:
The itty-bitty ones, not so much. However, I have a 3rd hand and a strong light and I know how to use them! 
Thanks for replies.
FYI, making dupont wires.

Gosh I hate DuPont connectors...
Been working with RC planes for a few years now and I hate how prominent these connectors are in the hobby world. Who sat down and thought to themselves, "Yoooo I have the perfect idea - lets design a connector that can be reverse-mated AND not make them locking"? Easy to reverse-mate and too easy to disconnect.
JST-XH Connectors are sooo much better IMHO:

I'm with you there. It's my go-to connector for anything up to 1-2A (above that it's screw connectors).
The tiny connectors are still quite fiddly to crimp, though...

Dang, I just buy them pre-made, lol
Only works if they are the correct length. Usually far too short. 1-2m is quite common for me.
For the benefit of anyone searching for these connectors - there are apparently hundreds of variations and multiple terminological choices - after a chat with Newark I got these links:
male, gold TE Connectivity pn 102095-2
male tin TE Connectivity pn 5-102107-3
female tin TE Connectivity pn 87756-6
housing TE Connectivity pn 7-87499-2
I get mine from eBay at fractions of the price.
1000 for ~$6.00
1000 for ~$5.00
x1 housing 500 for ~$2.00
Other housings

You can always solder on extra wire on the ends. Even still, I don't ever recall seeing 1-2m servo extenders... 
In my case it was for sensors. Not for servos.
Soldering was another option but still that'd need crimping as I usually need XH connectors on BOTH ends of the cable.
