Spring strengths...

I'm aware there are different springs available to upgrade or downgrade gearboxes so my question isn't about changing springs...

 

Is a brand new spring (lets assume an M100), power output (j's) likely to decrease over the first few hundred to few thousand bb's?

 

Asking as feel I need to downgrade a couple of my aeg's, some I can do myself by simply replacing the quick change spring, others I would need/want a tech to sort for me. If the new springs are likely to 'soften' over use I wouldn't need to do either.

 

Thanks in advance.

Double Eagle springs might be made out of Kraft Dairy Slices, they seem to go all the over place in fairly short order, but my other guns have held up quite well over time.  It's the ultimate 'YMMV' story.  So buying gats with quick change springs makes a lot of sense 👍

Depends how much you want to reduce the power.

You can reduce it around 5 to 10fps by leaving the AEG semi cocked for a few days.

 

Using AUTO do a quick trigger pull so it doesn't fully cycle so the spring stays compressed.

(It only works if it doesn't have a MOSFET to complete the cycle)

 

Leave for a few days and test again.  Repeat if necessary

Seconds to what Fatboy posted. A good spring should basically never compress, whereas bad springs can lose power very quickly, or even bend.

Yes...and no. All springs will lose power over time because their very nature makes it happen. Bad springs just lose power more quickly. The trick is using a spring that degrades at an acceptable rate.

I should’ve elaborated more—a good spring should experience little to no power drop over a minimum of 100,000 cycles, and hopefully much longer, but, of course, all springs will experience some power loss.

Using the springs to shoot the gun will have a small effect on the spring constant, but in Airsoft there are alot of cycles and the spring will get weaker. Airsoft cycles are quite deep and as others have said quality matters. Deeper cycles will have a greater effect than less deep ones.

Leaving it compressed will have large effect by comparison due to the permanent squish on it.

 

Potentially short stroking could extend its life, but I've always looked at springs as consumables.

 

Whilst other springs seem to have actual manufacturing specs, Airsoft springs don't seem to have even the basic info.

Thanks for the input folks, I've got a bag of springs heading my way to replace the OP one's, most of my rif's are wall hangers anyway so having a weak spring or no spring is better than having a hot potato or two.

Got a wee parcel from Huttarmouries yesterday, sure I'l find some springs in this lot that fit the bill.

Was looking at the pic for ages thinking it was wrong then read the comment on the bottom.

I've seen a couple of YT video's on how to test springs & had a home made device offered via messenger, in the end I gave the hot potatoes to our local tech to sort for me.

The pic is correct , the comment is wrong .

The numbers are compressed length plus the piston or cylinder, so a weaker spring has a shorter compressed length.

Preload may be an issue testing this way as the spring starts unloaded.

But it works for thier purposes.
