Ez hinges
 

One of the dangers of growing old and not taking good notes is sometimes forgetting the painful lessons that you might have once learned.
Another problem is not having the handy LHS sales help any more as a bac up system.
The hinges I recently bought via Tower were the Great Planes brand and the fuzzy part of the material peels away from the inner [smooth] plastic.
Years ago, one of the EZ hinge MFGs ran an advertisement that helped educate the consumer as to why their process was superior, why their hinges did not come apart before you could install them. It had something to do with how they abraded the raw material.
I wouldn't be posting this if I could remember which company that was...!

Thanks...!

C.Pig The material is used for insulation in electronic devices like motors, and transformers. It is referred to as DMD for dacron-mylar-dacron. I had a friend who used to sell the stuff, and from time to time, he would give me small sheets that I cut up to the size I needed. Gale Helms (Steve Helms dad)
introduced the stuff to the hobby. He stumbled on it in his work in the aerospace industry. It's likely that there are several manufacturers out there, and that the quality varies a lot. Greg.

Thanks Greg.
It looks like the thin plastic sheets are fed into "planer" that shreds both sides into the fibrous mat. The process is perfect if the roots of the fibers do not detach from the base layer of plastic sheet.

C Pig, I'll ask my source the next time I talk with him about the various manufacturing processes.

I remember the blue Radio South hinges had problems some years back.

I had problems with Sig Easy hinges a couple years ago as they were delaminating just while handling them. I called Sig about it and was sent a couple bags of new hinges and guess what? They also delaminated.
I used to like using those hinges but what with having so many problems I decided to forgo using them.
I now stick with Dubro pinned hinges.
Unless I hear from people who have no problems with Easy Hinges, I'm going to continue to use pinned hinges.

I rarely use flat pinned hinges anymore but like many people prefer to use Robart Hingepoints. 1/8" for smaller airplanes and 3/16" for any surface large enough to accommodate this size. Way easier to install than flat hinges and extremely durable.

I still use CA hinges in small planes but never in anything where a Robart hinge will fit in their place. Just too many problems with CA hinges in larger planes but they still have their place in certain applications.

Regarding the delamination problem, once glued in place the problem pretty much goes away as the CA bonds very well to the core Mylar material and the random weave cloth cover. I've probably had the best luck with Great Planes and Horizon brands compared to the SIG hinges as they seem more durable.
