Quality in workmanship

[YukonJack]

Curious what people think about the connectors that have the solder in them. You heat them and the solder melts.  Believe they are called Solder Sticks.

I love them. Make sure you get the ones with adhesive in them to give you a waterproof connection!  And the connection will not have structural strength until it cools.

 

I use a bic lighter,  it tends to blacken the shrinkwrap and potentially burn through. so it has a bit of a learning curve.  you might have better luck with a heat gun.

There is nothing wrong with crimping but one has to know what they are doing. As those have already stated, Quality wire, Quality connectors and terminals, Quality crimp tools all make crimping good enough to be used in the most demanding equipment for the most important military and space applications. Good quality parts and skill and it works perfectly. I agree with the thought that the cheap brittle plastic insulators is trouble waiting to happen, one is truly better off shrink tubing than using those types of terminals. I use bare terminals, use the right type of compression and then slide up heat shrink to insulate.  Most people do not have access to good terminals and connectors, nor the crimping tools to properly do the job. The suppliers are cheap as can be, a terminal costs a fraction of a penny. What people pay for a crappy hand crimper is what a very good hand crimper should go for. For those that know electrical connectors and fart dust like me, the man on the far left is Bern of "Burndy." Anyway....toss the plastic insulators so you can use the right crimping tools and then insulate with shrink. Solder does an excellent job but then there is the issue of the Shemp like "Knack, Yuck Yucks" and whole dropped testicle thing....

 

The pics of the poorly formed brake/fuel bends. Bending radiuses that tight cant be done with, once again, the tools most people will come across locally especially if the end is to be fluted. Still, when that happens it should be pretty clear there is a problem and one gets the tool...and or perhaps glasses. Knack....

I'm in the middle of a several-days-long job of installing a new engine monitor (see photo below) in the RV-6 airplane. The installation is FAA/PMA approved and the wiring hardware included with the monitor has crimped harness connectors which I install on the sender ends of the harnesses. These are AMP plastic-insulated ring terminals and I use a ratcheting crimper. This is standard practice in aviation and has been blessed by the FAA certification process. The 24 year-old monitor I removed also had crimped connections (like nearly every wiring terminal in the airplane) and all were just as tight as they were when I installed them two and a half decades ago.

 

Properly crimped plastic-insulated terminals are just fine for my P15.  Wonder if I could find room in the dash of the Plymouth for one of these!  ?

I use them all the time but they are not the brittle cheap ones. Those like poor quality aluminum terminals run a much higher risk of failure. That must be the new apple watch....nice!

 

I do still want to see Snipers movie though.....I've done some soldering myself and its got to be better than Netflix Cleopatra......

Don't hold your breath on my video, lol.  Got a lot of stuff going on right now, mostly health issues.

Take care of it brother, lots of people here counting on you.

I think I already asked someone, maybe you, for a recommendation on a really good crimper, especially for the bullet connectors.  I wish stuff like that could be in a "sticky", so it's always easy to find.

But speaking of expensive crimping tools, I build power cables for cables to connect to the pinouts on computer boards, and and the one I have, new, costs over $1,300.00.  But now the last couple of orders of the terminals are all a bit wrong somehow, and they stick in the die.  I have to use a small jeweler's screw driver to push it out, or it bends the tiny terminal all to thunderations before it comes loose.

Sniper we are all just having fun here. Health is the whole game. Get better asap....you are part of the best read here.

Yes, thank you.  I have a second appt tomorrow with my endocrinologist.  Last time he took 15 vials of blood and a half gallon of pee, lol.  That was supposed to be a 24hr collection, probably with room to spare, took me 8 hours to fill it.

It's not the dash you have to worry about, it's the sensors that will connect to the engine, the air speed indicator, the altimeter, propeller, and the gyroscope that would worry me. LOL
