Bob:



This may seem like a rather silly question, but what type of crimper do I

use to crimp butt splices......I've looked thru your website, looked at

terminaltown's website and even "googled" this questions and can't find

anything regarding what type of crimper is used....just instructions of how

to do it.



Thanks

Henry;



Different Bob, but a butt splice is no different than any other type of wire

terminal. Same crimper you would use for say a fast-on or ring, just that

you have two crimps, one on each end instead of just one.

Pretty much any type will do, if you're talking about the splices like these:

A good choice is a ratcheting tool like the ones here:

   Successful use of ANY wire termination device that

   functions by "mashing" begs understanding with

   respect to designed wire size along with dimensions

   and shape of the finished joint.



   A huge range splices are offered that speak to joining

   wires with equally large array of design goals. This is

   why I've focused the majority of my suggestions for crimp-on

   terminations on a small constellation of products

   embraced for decades by the type certificated aircraft

   industry. I've written at length about the AMP PIDG

   (Pre-Insulated Diamond Grip) devices which are part

   of the Mil-T-7928, Type II family of products offered by dozens

   of capable manufacturers.



   I did comic book . . .



http://aeroelectric.com/articles/CrimpTools/crimptools.html



    . . . that compared two tools suited for application

    of devices in this family of terminals . . .



http://aeroelectric.com/Pictures/Terminals/s816p.jpg



    which includes knife and butt splices . . .



http://aeroelectric.com/Pictures/Terminals/knife_splice_1.jpg

http://aeroelectric.com/Pictures/Terminals/PIDG-Splices.jpg

http://aeroelectric.com/Pictures/Terminals/ksplc2.jpg



    Now, just because someone says, "My terminal is (better/

    same) as the other guy's terminal does not make it so.

    Here's a low cost terminal I evaluated some years ago

    with the notion of offering them as alternatives to

    the AMP PIDG terminals . . .



http://aeroelectric.com/Pictures/Terminals/JST_Samples_2.jpg



    Electrically, these terminals went on well using

    tools already on hand for installing PIDG devices . . .

    but you can see the difference in how the insulation

    grip was treated. Needless to say, I didn't switch my

    inventory to offer these devices.



    In terms of butt-splice alternatives, there's a host

    of options. We looked at these critters a few weeks

    ago . . .



http://aeroelectric.com/Pictures/Terminals/Krimpa-Seal_Butt_Splice.jpg



    Crimped splices with built-in heat-shrink jackets. Pretty

    cool. Worked good. Will last a long time . . . but DO NOT

    apply well with PIDG rated tools.



    Here's a cut and paste from a message I posted some time

    back that suggests a tooling-independent technique for

    joining wires:



-------- start of excerpt ------------------



    We know that solder sleeves have a wide following in aviation

    and other venues for splicing wires.



http://www.mouser.com/catalog/619/628.pdf



http://workmanship.nasa.gov/lib/insp/2%20books/links/sections/406%20Solder%20Sleeves.html



http://www.raychem.com/US/datasheets/REVISED32004/Sec_8/8-006_8-011_SolderSleeve.pdf



    So, if we can get past the ol' saw about "make it mechanically secure and

    then solder for electrical integrity", how about this?

http://www.aeroelectric.com/articles/PM_SS_Splice/PM_Solder_Sleeve_1.jpg



http://www.aeroelectric.com/articles/PM_SS_Splice/PM_Solder_Sleeve_2.jpg



http://www.aeroelectric.com/articles/PM_SS_Splice/PM_Solder_Sleeve_3.jpg



http://www.aeroelectric.com/articles/PM_SS_Splice/PM_Solder_Sleeve_4.jpg



http://www.aeroelectric.com/articles/PM_SS_Splice/PM_Solder_Sleeve_5.jpg



    This technique provides equivalent mechanical and electrical integrity

    with your ordinary hand tools for a lot less cost than pe-fabricated

    solder sleeves and splices. The only edge I can see for solder sleeves

    is the sealant included in each end of the sleeve . . .



    I'll suggest that the technique described meets our needs nicely

    for a fraction of the cost. Bulk of the slice is small too.

    However, if you're splicing a bundle of multiple wires, it's still

    a good idea to stagger the splice locations along the bundle.



----------- end of excerpt ---------



    Sorry if this seems like a data dump from a big bucket but

    I think this illustrates the potential for error in

    communication by limiting your query to "butt splices"

    when it comes to tooling.



    It's important to know the style of the splice for the

    purpose of offering suitable tools. ASSUMING that you're

    wanting to install these guys . . .



http://aeroelectric.com/Pictures/Terminals/AMP_PIDG_Splices.jpg



    you use the same tool as the other PIDG devices illustrated

    above.



    But consider adding the lap-soldered splices covered with

    heat-shrink to your bag-of-tricks. They're lower cost, smaller

    volume, and just as reliable as the PIDG splices and

    even NASA approved. See section 19 of . . .



http://www.aeroelectric.com/Reference_Docs/NASA/NASA-STD-8739p4c4.pdf



    . . . and know that there's a lot of options available to

    you for joining wires in your airplane.
