Jones" Bob is right-on regarding Bakelite. Nylon, acrylic, or glass-epoxy will usually do. When I have time I would like to write an article about the fine art of choosing materials. This is not as simple as it sounds, but you get a whole lot smarter if your choices are limited. Some materials become fashionably and then fade: Viz--Teflon. It was once the wunderstuff, now engineers would furrow their brows if one uses it. The DC-10 that crashed in Chicago years ago had some teflon bearings. The investigating engineer commented, "There's no place for teflon on an aircraft..." There are only two or three legitimate uses for it, and that's it....and forget it because the thing you're designing isn't one of them. There are many people who can hardly believe they build airplanes from wood! When I was in school I build camera lensboards from paper and glue and india ink. They were still in service until I got rid of all my film-based cameras. -------- Eric M.

Having read the info on the AeroElectric site regarding aviation quality crimped terminals I feel I am much more informed as to their correct use & installation but I do have a couple of questions. It would seem that adding a small piece of a good quality shrink wrap, most likely clear, over the terminal & the first portion of the wire entering the terminal (in this case shielded) would add to the overall strength & stability of the double crimped assembly. My questions are: 1) Is this legal on a certificated aircraft? 2) Any compelling reason why this should not be done? Thanks for any replies. Johnny ________________________________ Message 6 _____________________________________ Time: 01:43:52 PM PST US From: "Jay Hyde" Subject: RE: AeroElectric-List: Aviation crimp terminals. Johnny, It's a very good idea to do that- however, there are times that it is not required. The shrink wrap (by which I think you mean heat shrink), properly applied, provides a great stress reliever to the wire/ crimp joint. Generally I apply three layers of heat shrink- a long thin one first and then two successively thicker ones, where the last layer goes over the insulation of the crimp and then onto the two layers on the wire, so that there are graduated layers of material that absorb vibration and provide stress relief. I do this in areas where the wire does not immediately go into a bundle that will support it from vibration. Where you have a wire that can immediately be supported you do not need this stress relief.

Some members on the List may recall some discussions about Teflon insulated wire here on the List about 9 years ago. Use the search engine on the front page at AeroElectric.com to find references to Teflon. It's a neat material that is unparalleled for a few applications . . . but as you've stated . . . very few.

Where do you perceive a 'weakness'? My questions are: 1) Is this legal on a certificated aircraft? I've never seen it done . . . I'm not aware of any prohibition either. But anyone with much experience in aviation would ask you the same question I posed above. 2) Any compelling reason why this should not be done? Adds weight, time, cost of materials and bulk to a wire termination without demonstrable benefit.
