How to break an AEG

Running a stock AEG to its death on 12 volts.

I think this should be in the FAQs for newcomers to watch...well, I doubt they'd see anything in the FAQs, but...it should be there for those who are new to the sport and have delusions about running a gun with a battery that's too powerful for the sake of increasing their FPS/ROF/range/whatever.

The sound in the end really hurt in the ears...ewww..

ouch! :smack:

each time you break a gearbox a little chinese baby cries :(

So right!
My first gun was an MP5SD6 from airzoft.com. I hooked nine sub-c cells to it, and hung them under the foregrip like a triangular grenade launcher. I could empty the mag in about two seconds with it.

After three weeks of intermittent use chasing off crows, it finally got too shrill to listen to. The plastic gearbox and gears still technically functioned, but they were all worn, especially the bevel gear and the piston gear. Their "bushings" were toast, but it was interesting to note that the middle gear's axle/bushing wasn't worn near as much.

So I got to learn right off where most of the stresses are in an AEG geartrain. This has come in handy when modifying things.

As I've moved on to the "MPEG" type guns (I have but two Marui's), I've gotten to see firsthand how much their quality has improved over the past year, and I'm impressed with how some of the "cloned" components are better than the things they copy.

Watching the video, did you expect the gun to still be operational after a minute and a half of constant running? I was surprised myself. A new set of bushings and a piston to replace the chewed original, and this gun is ready for another run. Wow.

I think we have some thanks to give to the Noob's out there, if they hadn't been breaking new cheapies and causing pain with product returns, Chinese clones would still be made from medical waste-quality stuff.

I bought 3 SCAR clones (JLS) when they were $169. Now the price is $139, and the bevel gear and piston gear both have metal bushings stock. A reinforced piston, and a nice .052" spring (~M120) are in there as well!

Are You a Noob?
I was, less than two years ago. The MP5 didn't have to die! But what I learned from tearing it apart (it's components live on in other items) was worth FAR more than the $39 I paid for it. So don't feel bad if you've wrecked your first gun with excess electron flow. In fact, please be a good customer and break products daily, and harp on the mfg when you find faults.

Being a gun manufacturer myself, I secretly enjoy hearing about my product's shortcomings, because every one presents an opportunity to make them better. If you have an AirSharp product and aren't happy, I want to know about it. My "Dirtbike Warranty" policy means the item is your problem if you break it. But come to me with an honest issue in a businesslike manner, and I will do all I can to fix your problem.

-I haven't charged one customer yet for a replacement item, or it's delivery cost!

I should point out that entertaining disaster stories get special attention...

That poor styrofoam box. And I hope that I never encounter any player using a box mag like that in a game.

looks like basic friction killed that mechbox. damn that musta been one warm aeg after 1500rds

SMASH SMASH SMASH SMASH "THAT DOSN'T SOUND GOOD" lol nice

nice...

I feel bad for that cooler... me and my family use to take those style coolers to the beach at the cottage all the time... till uncle Gerry swore it would take his weight anyway...

Now there are 24 beers out there that will never be cold...

And is it just me, or did it look like some of those BBs (2nd clip) bounced off the glasses there without destroying the glass?

It was actually packing material from a gem globe. My beers are safely cold, for when it's five o'clock somewhere...
The thick factory-second glasses I got at the dollar store are pretty tough.
That's why I used the SPR. It shoots good and hard.

Did you find that your SPR is a bit 'light' overall? My buddy has it and that's the first thing we both noticed, otherwise a nice AEG.

Kind of wasteful just to destroy a mechbox for S&G. A follow up video of them taking apart the mechbox and finding what had broken and what had excessive wear would have been much more interesting.

Pics coming. The mechbox was in amazingly good condition. A set of bushings and a piston is all it needs to run again. I took pictures of the autopsy, I will post them later today.

I did this because so many noobs (self included) hook bigger batteries to airguns in hopes of better performance. All it does is make the motor run faster.
The OA93 pistol had a stock mechbox in it for construction purposes. I have a hot-rodded one going together for it, so I thought why not show how well the "metal gearbox" in the current crop of MPEG's hold up.

I have lots of parts on hand (I have over 30 personal guns, in addition to building the 1919's, M2's, Stingers, and running a Chinese M14 clone parts business), So chewing a piston for the sake of illustration was good math.

I have to hand it to the cloners...a minute and a half of continuous operation at nearly double the stock voltage (12.89volts on my old Beckman meter) is impressive alone. The fact that it can be fixed with $30 in parts shows how far we've come.

Sorry if I sounded too judgemental. Thanks-->Autopsy photos ftw. Bushings and piston only :p?
SHite I thought it was going to look like

Ouch is right!

thanks killbucket...you should fix the gun for when the zombie's come!!!

Here's pics of the total damage. Not much to fix here, note the piston teeth tearing away. On a cheap piston from two years ago, the last one or two teeth would have torn off, taking a portion of the piston skirt. Here, we just have the tips of the gears coming apart. Much better composites in use.
Then the bushing on the gear. Considering the abject ABUSE I gave this poor, feckless gearbox, this is amazing. You can see how much wear there is by the deflection caused when I pinch one side of the assembly. Again, a part from 24 months ago would have welded to the shaft when it stopped, or had a gigantic hole in the middle.
If you think about it, I didn't complete my test, as the gun WAS still "operating" at the stop. I imagine some noobs would continue to run the gun, because the change in sound could have been missed as the parts wore over months instead of moments. If the gun was returned to use in this condition, it would function until the last few teeth wore off the piston.
The gear appears to be pitted, but that's piston teeth bits stuck to it.

That's the exact thing that happened to my Guarder reinforced box except it was only one side that was broke. Thought maybe some JB Weld would hold up but that was a no go.

I was about to get one of the guarder reinforced GB sets. Were you running it at excessive power levels or anything of that nature?

It was only shooting around 380fps and was installed by a gun doc. I think it was Illusion that told me he has always had trouble with Guarder GB's. I have Guarder internals and love them so I hope it was just a bad box.
