Question for Jimmy concerning omega springs

PS: for those attempting to form some springs here is one tool I use for such work.
There are even better spring benders but they are complex and more expensive things with movable pins and dies.

These pliers are pretty inexpensive. They are made in smaller diameters than shown. Ironically I use them for taking kinks OUT of things I want to straighten.

This is really great that you posted about this; both of you. Thanks.


Will you be more specific ? Was the end splintered or was it cracked part way straight across and shiny(ish) part way across (probably take good magnification to say). Shame it got thrown away.

For some reason I thought the wire might be square in cross section (rather than round in cross section).

More like splintered and torn kinda. NOT cracked straight across. Looked something like this:

What do you get out of that?

Double blowout! My 940 went down today too! Weird.

Here are the pictures, sorry for the crappy cell phone quality.

Hi guys,
Sorry to be so tardy. I got all caught up in watching the totally AWESOME program on the eclipse on NOVA ! ! !
I worked inside all day and was not able to view it but the PBS show sure made up for it. Riveting !
anyhoooo back to broken springness :

First a few quotes to demonstrate that I realize how lame my “science” here is.

My story world hero will now take the podium for a few moments :

‘It is a capital mistake to theorize before one has data. Insensibly one begins to twist facts to suit theories, instead of theories to suit facts.’
Sherlock Holmes Quote
-A Scandal in Bohemia

‘I never guess. It is a shocking habit,—destructive to the logical faculty.’
Sherlock Holmes Quote
-The Sign of Four

“It was most suggestive,” said Holmes. “It has long been an axiom of mine that the little things are infinitely the most important.” – A Case of Identity

“I had,” he said, “come to an entirely erroneous conclusion which shows, my dear Watson, how dangerous it always is to reason from insufficient data.” – The Adventure of the Speckled Band

OK

Since I am no Sherlock Holmes I am going to guess based on the minuscule data/details (only two examples though nearly identical) but VERY MUCH APPRECIATED none the less !

thanks for taking the time ! ! ! !

My thoughts :

When the wire was manufactured it may have been drawn too fast through the dies and or the lubricants were insufficient and this caused the grain of the steel to separate and have voids. When flexed many many times in the knife the voids were the STRESS RISER that caused the steel to crack apart from the inside out.

If

there had been higher quality control of the wire . . . but . . . there had been a scratch across the wire and it HAPPENED to be on the outside of the bend then the crack / shape of the ends would have traveled perpendicular to the outer surface of the wire and the broken ends would have been some what more square across rather than as they are; very angular/triangular/wedge shaped.

Sorry my vocabulary took such a nose dive there. Hopefully some one here can decipher what I was TRYING to say and put it into modern english.

AND

if I am full of shavings everyone please feel free to blow my GUESSING out of the water.

That’s fine and I will learn some things.

Cow51 Cow51 Looks like we had the exact same kind of failure.

I would also guess that these three cases of failure are results of some kind of fail in manufacturing.

I have even more high hopes for the longevity of my beadalon springs(look post #37) now. I installed them successfully a couple of days ago. Running smoothe so far.

I've made some from the beadalon memory wire as well. They work just as good. Actually a little stronger feeling to me. I would make sure you get the stainless steel version though. They have a non stainless version as well.

I measured both the OEM spring and the beadalon wire, they are about the same diameter. Maybe the beadalon was a tiiiny bit bigger but not by much.

But the finnish on the beadalon is much better, really smoothe and high polished. Maybe they'll last even longer than OEM springs? Time will tell.

Cool thing is; when you buy a pack of beadalon you can probably make +- 50 omega springs from it. :cool:

Yes they look bigger.
Doesn't take much.
I would not want the spring rate stronger than the stock springs that is for sure.
Do they offer a smaller gauge wire ?
 
I would really like some hard core feed back on my guesses.
I am thinking of starting another thread over in tinkering forum or even . . . brace yourselves . . . the general discussion forum.
Come on guys geek out !

I have no idea. But I measured both with calipers(non digital) and even then it was hard to tell a difference.

The action when installed is very nice, not to stiff.
