#102197 Titan Missile Launcher
Posted by kaiman299 on 14 April 2007 - 02:59 PM in Homemades
I've made my titan into a missile launcher-type-thingy. It has a 1' long sch 80 PVC barrel. The "missiles" are water bottles. I have found that they slide quite easially over the PVC and have a fairly good seal. The problem isn't how well the bottle seals. In mid-air the bottles will flip and tumble loosing all of their momentum very quickly. i'm pretty sure this is because of their lack of mass.
If anybody could suggest ways that I can modify the bottles to make them more stable, or a completely new missile, that would be great.
Thanks

About 4 months of intense yo-yoing pays off.

Ok for your trigger, I would go with an oversized double clothespin trigger. I would use those big siczor clamp things, put a hole through the front, and then stick a huge bolt in there.
For the plunger, just make it the same size as your tube, and have about 2-3' of draw. As for making it airtight.....Maybe a huge o-ring or just go with pipe insulation.
To get the endcap on there... get a piece of PVC pipe one size smaller (for instance, one size smaller than 3/4" would be 2/4" or 1/2") Cut about a 3 inch length and hammer it in there. Then secure the end with a endcap and glue it on with primer and cement.
Have fun, and where the hell will you get a 100 lb. spring?

Ok if your problem is that when you pull the trigger, and it only shoots out of 1 barrel, like this:
Hornet Video
Then you need to look inside the slide. There is a little latch inside that if not set correctly, The gun will only shoot out of 1 barrel.
And heres what it should look like:
Be sure you have that little spring in there.
Hope this helps!

The original handle was pretty weak. It would move all around and fell off twice. My new handle is screwed on, for easy access to the trigger, and a sturdy hold.
Next, I fabricated a pump action. The original plunger was hard to hold, and pull back, not to mention the ends were very sharp.
Breech closed.
Breech open.
All thats left is to find a name, and give it a black with orange flames paintjob. Help on names would be greatly appreceated!
I had to remove the magazine to add the pump, but I am planning to put it back on.

I do have a question though: would having the barrel be nested brass, with cpvc hammered into the pvc the bras is inside possibly cause the dart to catch, thus decreasing range, or would it increase range, or should I make the whole barrel brass?

Basic Mav turret with the bottem removed. Nothing special.
I filled the turret with some of this stuff I bought by accident instead of plumbers goop.
Then I shoved this thing in the back of the turret.
It fits perfectly in the back of the turret and has some threads for a piece of SCH80.
From left to right: CPVC, 1/2" SCH40 PVC, 1/2" PVC Coupler, SCH80 PVC.
Thats the whole attatchment.
And there's the coolest titan ever! (well not really)
Enjoy. Remember to post your own attatchments to any gun.

Yeah, I know she's big. Basically, its a bolt action breech loading rifle. Magazine is to come soon!
Here's the plunger with the springs:
And now for the bolt and the breech:
It has a sort of plunger at the end as well to have a good seal on the plunger tube. It's the part that actually cocks the gun, but is part of the barrel also. The breech design is based after this:
Here's the trigger:
Just a clothespin trigger.
And now the stock with plunger attatched:
Enjoy! The ranges are 80' max. 60' effective. Any questions/comments would be very much welcome!

Posted by kaiman299 on 15 May 2006 - 04:34 PM in Homemades
Edit:
Ok about everybody said it looks "ugly" So I decided to paint it. Here's what I got:
I think it looks much better now. And just so you know, I left the tip of the barrel white for a reason.
Updated ranges:
72' flat.
97' angled with slight breeze.

It looks pretty cool. Nice job. How does it work though?
The CPVC you see begind the trigger is the bolt. It is connected to the plunger shaft, which is CPVC, with a notch cut in it. WHen you pull it back, the catch made out of plexi-glass gest pushed into the groove by a spring, thus locking the plunger back. When you pull the trigger, it lifts the catch, releasing the plunger. The spring is a BBB spring.

how far does it shoot? farther than any other nerf gun i hope.For the record, we have no info on ranges or anything like that. Nothing to measure with, but by sight I think the Magstrike out performed a PC.
That's pretty much self-explanitory.

It has a CPVC coupler barrel, and gets ranges of 60'! For my first homemade from scratch, I'm Very Happy!
#81614 Rapid Fire 20 Firing System Mystery Solved!
Posted by kaiman299 on 09 May 2006 - 09:14 PM in General Nerf
Is it me or did 99.9% of the world figure this out already in fact did you know that all nerfguns use air ?
Well that sure took a genius to figure out. Have you noticed that ALL guns also either use an airtank with a valve, or a spring powered plunger? Good for you . Although all nerf guns use air in one way or another, I specified THE METHOD of how the air is compressed and released. Usually if a gun uses a spring powered plunger, it is referred to as a spring gun. If it uses an airtank or bladder, it is referred to as an air gun.
If you're going to go off criticising everybody aboud crap, make sure you actually know what you're talking about, and try to make it constructive.
I know I basically repeated what Ompa said, but I went into more detail so thay you may have a chance to comprehend an extremely simple concept.
#81600 Rapid Fire 20 Firing System Mystery Solved!

Examining the spring shaft.
I actually stumbelled upon this by accident while I was half-asleep, and just screwing around. I pumped the gun once, and pulled the trigger. Obiously, the gun didn't fire, and the piston didn't advance fully. So, I pushed the turret slowly in, and to my suprise, the spring didn't push anything forward! This showed me that the whole assembly is one big valve! To better explain this, here's a video:
Now take a look at these pictures:
Valve open
Valve closed
If you look closely, when the trigger is pulled, air pushes the whole tube forward, thus releasing the big black rubber thing's seal on the tube. Then the air is allowed to flow for a split second, untill the spring forces the tube backwards again, restoring the big black rubber thing's seal on the tube.
From this comes my conclusion:
The RF20 Operates on Air Power!
Thank you for your time, and if you have any questions/critiques, pleast tell me.
