I've read the article and the man has more experience with these things than me for sure. I am posting my observations.

To say that you are not going to solider anything on an airplane because you are afraid the wire will be brittle and break does not wash with me. Two weeks ago I had a switch replaced in the control colume of the Learjet I fly for a living. The switch had been in service for over 8000 hours and the wires were soldered to it. The wires weren't the problem, the switch was bad! There was no way to crimp a wire to the new switch, it had just a small ring lug. So the A&P made a good mechanical connection soldered it and covered it with heat shrink.

I am not trying to challenge anyones expetise, just reporting my observations.

Steve

I'm about half way through Bob's book. I also re-read the article below. I'm just having a tough time visualizing how a crimp can be air / moisture tight... even a super pressure crimp.

My other hobbies include outdoor / garden model trains. I don't see many crimps in the pieces designed for outdoor use.

I've worked with some eletronics as a hobby for a while. I've even designed and cut a few boards for things like Infra Red train position detection. I think Bob has alot of excellent information, but I'm going to have to disagree with him on this one.

Okay, Boeing used crimps on the B-25 way back when... what are they doing now?

I do agree with Bob on those stupid terminal blocks though. Use the closed loop terminals... your going to need them! A good lesson for me was a screw on my motorcyle that kept coming off. I would tighten it as tight as I could... a few days of riding and heavy vibration, 'poof'... gone! I think it was supposed to have a locking washer. Wasn't critical, just a motorcycle stand spool on the swing arm. Lock tight solved the dissapearing screw problem. But if anyone thinks those simple screws on the terminal block are staying put inside an airplane... I wish you well!

That just blew that guys credibility as far as I'm concerned. Certainly didn't help my case. But I still prefer sodering connections. I've seen the terminals that support the wire out beyond the soder connection... seal that up with the silicon gunk and heat shrink it. Well that's the theory.

Maybe you could be the first?

LP has perfected comic sarcasm
and MT has learned restrain.

That's what this forum is for. Pushing out the edge of the envelope.

My favorite line from Groundhog Day, Bill Murray to the Groundhog: "Don't drive angry... DON'T drive angry."

Or from "Ferris Bueller's Day Off":

"He's so uptight, that if you stuck a lump of coal in his butt, in a week you'd have a diamond!"

OK - a bit off topic - but it does refer to 'tight'

My favorite quote. From Cool Hand Luke..

Strother Martin's character, the warden, "What we have here, is a failure to communicate".

One of the best anti-establishment movies of all time. Any wonder I want to "go against" the grain and widen the fuse 3"
