Can anybody give me a good lead or two on quality
crimpers for lucars? Not the bullets but the small
female space uninsulated ones? I have the proper
lucars and covers but no tool.
These are not the common insulated type, usually blue.
 
Soldering is not really accepted practise any longer. Crimping
is less likely to cause a break due to hardening of the cu.
However, I have what look to be stock bullets that were soldered
and the are fine.
Prefer crimps anyway. Proper ones, using pro tools.

Done, insulated, and stress-relieved properly, soldering is by far the best way to make electrical connections. IMHO, of course.

Is this just for motorcycles? I'm assuming that this is for a loose wire that gets fixed at a junction . On a bike that vibrates a lot it seems that all connections, regardless of friction (crimped) or soldered, need to be secured so that a junction is not significantly stiffer than the wire to which it is attached. Any scholarly articles to quote about this??
 
There are a few brands now that do replacable jaws so you get 3 or 4 different crimping tools in one set, I purchased one from Teng tools with 3 interchangale jaws

I respectfully disagree that soldering is the best way to make elec. connections.
Particularly in vibration prone areas, crimped connections are by far the best way to go.
For this reason, in the aviation industry almost all electrical connections are crimped, and soldered connections are rarely used.
 
I use at least 2 crimpers for connecters, the thin one and the wide pliers’ type one. But please be aware that some of the un- insulated connectors have the rear tabs, the ones that crimp onto the insulation - are too long and need to be trimmed (shortened) to fit motorcycle wiring for best success.

Soldering has not been used in any industry for wire and terminal connections in 40 years. In the boating industry, industry building standards and including USCG inspections, solder only connections are not allowed. Solder does not have the same conductivity as copper terminals. Stranded copper wires will fracture at the edge of the solder. Some like to crimp and then solder. With a proper crimp, the solder will not even enter the crimped area. But car guys, boat guys, and motorcycle guys continue to solder. I'm currently working on a '74 Commando, bought at high dollar as a 'restored Norton Commando'. Lots of soldered wire bullet connectors. Terrible job, insulation all melted, wires stiff and bent at the solder. A mess.

Is that 40 years ago from today or 40 years ago from 8 years ago?

Not wishing to disagree with the Nautical view certainly in my days in the RN tinning the ends of cable was a absolute requirement to stop capillary action in the event of water entering into junction boxes
 
My Atlas has soldered bullets .... no problem in nearly 60 years. The problem with soldered connections is that the connection and the adjacent wire (or a part soldered to a substrate) must not be allowed to vibrate independently of each other. That is why potted electronics are immune to vibration, but a single component soldered on to something else will shake off.

Never solder (tin the wire ends) then crimp a connection .... the solder creeps over time and pressure, and will loosen. Crimp, then solder is okay.. with a proper crimp, solder is not necessary,

I would suggest, that if soldered electrical connections are disappearing from various industries, that it is more a matter of cost, than any concern that something else is better. Easier and cheaper to get an unskilled worker with little pride in his job, to make an adequate crimp, than to properly solder.


BTW.... someone on this Forum suggested using the cut off end of a cable tie to make a soldered splice rigid. Lay the plastic strip along side the wire, and shrink a piece of tubing over it to prevent the wire and the joint from vibrating independently of each other.

Slick

Absolutely correct
