I know this modification has been mentioned in THIS thread. But, either my computer won't load the pictures, or the links are broken. Anyway, on to the write-up...


I was happily playing around with my Big Bad Bow, when I heard something break as I shot. Then, I couldn't cock the gun and it was acting goofy. I took it apart, and realized the little disc the is under the plunger head had snapped!



I wanted to reinforce this disc, but I also needed to keep it removable to be able to switch the spring. I decided to use a metal washer like TriggerHappyAzn in his thread. This is the washer compared to the disc.





I decided to cut the metal washer to fit over the disc, yet not conflict with it's removal. I set up the disc to be cut to align with the slit in the disc.





I put two metal washers on in this way, one on each side. I used super glue to attach the washers.





It fits on like this.





Plunger assembly together.






I've put about 100 rounds through the BBB since this modification, and everything has held up great. The washers have stayed attached with the super glue and the disc has not snapped.

The washers cost about $.09 each. So this, in my opinion, is a great reinforcement that is incredibly cheap.

Agreed. That's the EXACT same place mine snapped. Nice write up. Do you know what kind of washers they were? Like what size?

Yeah, sorry. They are 5/16" washers.

1)So I am guessing this is pretty easy and at the same time definitely worth it?
And it is cheap.
2) Good job Coop.
3)By the way I say you Longshot on youtube.com, and it is great. Good job.

Slug style:

1) Yes. Especially when the disc is completely snapped.
2)Thanks
3) Thanks! Glad I got some views!

This is really awesome. I need to do this to my BBB because I just replaced the spring.

Then I'd say it's almost a must with a spring replacement. I didn't even replace my spring when mine snapped.

Good. PS: Your seal is upside down.

[Coop]

Just Some Bob. That may work... But dremeling out that circle would take quite a bit of skill! I don't think I could drill that fine with the circle cutter bit. I was at the hardware store anyways, so it wasn't a big deal.

Longshot Wielder: Do you mean my plunger head? I don' actually remember how it was when I took it apart, but I think that's how it is supposed to go.

[Shrub]

Yeah. It is upside down. The Plungerhead.

No, he has it right.

Thanks Bobafan. I thought I was right. If you look at the head, you can see the seal, and how it is slanted. The draw is easy because of the curve, then when it fires it fills the plunger tube.

[Coop]

I'm pretty sure it's right...

That's been stated, but thanks!

This is very nice, but for just a little more money ( or a lot) you can use a machine washer in stainless, brass, copper or otehr higher quality material that will not rust and would be easier to work with in some instances.

All I have is a dremel and I did it fine. If it rusts, I'll replace it with $.18 washers. No biggie.

This is pretty much what I did when I put a new spring in my BBB.

Just a little off topic question:
How many/what spring(s) did you put in your BBB to make the orange part snap like that?
I've only used stock NERF springs, but I never use industrial ones...

All I had was the stock spring. I think it was how I assembled it or something, not the gun. But this is just to make sure it won't ever snap again. I do plan on adding a spring, but not sure what type yet.
