The form of valve used in the Hornet (and the Blastfire, Triple-strike, and Secret Strike Pocket Blaster) seems really prone to errors... Sum up all the problems with the aforementioned guns, and you have the many failure modes of this valve (if the link doesn't work properly, my apologies; I can't view my site from Canada anymore. Blasted Web1000). Really exact builds required. My prototype facsimiles experience the same problems. Very annoying.
My suggestion? Oil, pressurize, pray. Sorry to hear another casualty of chance; best of luck with the Hornets.
Welcome to the forum Joselyn. Good sig reference.
Hrm... so that's how a ss2's tank works on the inside. I always figured it used levers and a tank ressembling the 5k's. Perhaps I should have opened one from the stack I was sitting on a while back.*
Ooh! Airsoft knowledge applied to nerf! Don't want to revolutionize the nerf biz, but we should REALLY be using silicone petroleum free lubricant. Seeing as petroleum based products wear down rubber and latex parts something awful, they may temporarily seal a gap, but will eventually deform or make it crack. My Crossbow's plunger was a prime example, god that thing looked nasty until I finally had to replace it.
Where do you get silicone lubricant? Go to a rc hobby store and pick up a little bottle of lubricant. Remember, the higher the weight the thicker it is.
Why not use aqua-lube, KY, or some other more readily available lubricantt? Well besides admitting to yourself the intended purpose of said lubricants, they are a bit too thin compared to the high weight silicone lubricants. Plus, do you really want your air tank to "sensually heat up"?
As for my Hornet, no problems yet, but seeing as the outbreak of trouble, I wouldn't be suprised if mine ended up broken.
. but then when i was pumping up the hornet, it made this really loud leaky sound, like pisssssss, so i was like OH Crap! So then i opened it up and found out it was leaking from the middle barrel, the one on the right when you are shooting someone. On the barrel the manufactures marked a what seems like a 4. i also found out that my lower barrels, also one on the right, has this wet stuff in the pipes connecting to the airtank. My hornet leaks so much that even when i shoot it right away the darts only go 2 feet. I know i didnt blast the tank, because i didnt plug up the pump yet. What the heck should i do?
