Sm1500 Over Pressurize / Shoot Mod

11 March 2007 - 01:05 AM

Hello,

Recently I have been having major problems with my SM1500. After I plugged the pump, the pressure in the tank would be too powerful, and the trigger would not have enough force to pull back for it to release all of the pressure. I usually would have to wait until it decompressed (which could take hours, to days) or open it up and pull the release rod manually.

Here is a mod I used to allow me to shoot it even when over-pumped / pressurized:

Tools:
- Pipe Cutter (I used one where you rotate the item until it cuts)
- Pliers that with cutting edges
- Screw Driver
- Cheap Bic Ballpoint Pen

I quickly diagnosed the problem
It seemed that the problem was that the spring in between the trigger mechanism and the release rod compressed too much where the spring would be compressed rather than give enough force for the trigger to pull the release rod back. I knew I had to replace this with something harder, so I gave one of my 1000 pens a try.

Note: Now when pulling the trigger, you may notice that it will be less cushioned as the spring will be replaced.
Also, you will notice that more air will come out of your barrel and it will possibly be louder.

Instructions
Open your SM 1500, and locate the Trigger mechanism and the release rod. There should be a metal rod, with a plastic end and a spring in between the trigger mechanism and the end of the release rod.

Take a bic pen, and cut a segment off about 1CM in length with your pipe cutter. Make sure it is nice and even.

Cut a line straight through the side of the cylinder. (----)

Move the existing spring on the release rod where it will not affect the trigger mechanism and place the bic pen section between the end of the release rod and trigger mechanism

Close the gun, pump a bit more than you should, and shoot. It should now work.

Frozen Plasticine - Bb Like Ammunition

05 March 2007 - 01:49 PM

Hey, I probably have not visited any of these forums for about, 2 or more years now. But, I have something to tell, so I decided to share it with the communities.

Recently, (more like, yesterday) I felt like finding something new to shoot at one of my friends who was over. We were, fortunately - using plasticine to mold a project for a biology class. My Stefans were tucked snug away under one of my seats in a ziplock bag, and I found they went to slow anyways, so I took one of the plasticine chunks in my hand and quickly rolled it into a sphere.

I rolled it down the barrel of my SM 1500, expecting it to flop and fall after 10ft just like all the other items I have placed in my gun to attempt to shoot. I pumped it 3 times, and wam. It smacked so fast against the wall on the other side of my basement.

Not only did this little very non perfect sphere I had made with plasticine in 2 seconds fly as fast as one of my stefans, it also stuck to the wall just like a stock micro would.
I didn't like them to stick though, even though it could be cool.

So, I decided to sharpen my talents of making these plasticine balls, and fire them at my friend. After, shaping one better, a more snug fit inside of my barrel - I shot it at my friend from about 20-25 ft away, and it left a welt on his back. A large bump that was extruded from his skin, and it was mighty pinkish red. He rated the hurt factor to the pain he gets when someone shoots him with his Airsoft handgun.

Not bad. Plasticine only costs 2.99$ for a large chunk, which translates into about , 500-1000 of these darts.
Not only that, when you freeze these little darts, they turn almost rock solid and they fire amazingly. They don't splat against walls, they bounce off.

You guys want to take a try at these? They work wonders. Also, works great for people who don't like getting hurt too badly.

Frozen = Pain (can also leaves dents in your walls, that look exactly like Stefan dart dents)
Room Temperature = Medium Pain (moderately sticky to walls)
Warm (just molded) = Feelable, and very sticky to walls.

The diameter of the spheres should be a little bit smaller, than the diameter of the inner diameter of your barrel. Some of the bullets that I made which perform best are almost snug fit, and require a blow to get them to the bottom of the barrel, however ones which are smaller and do not require this blow barely lose any range, power or accuracy.

At3k Help Asap

One of my Airtech 3000's was messed up, in the barrel side, so I decided to just single barrel the darn thing.

For some reaosn, (this is my second at3k mod) I cannot remove the barrels. There is that stupid cross metal bar that doesn't allow you to pull out the darn barrels! >=(

I have used extensive amount of force. Small Pliers, Huge Pliers, Hammreing it, and it just WON'T move.

How can you remove this dumb set of orange barrels??? Please help me.

Very Simple 1 Way Valve

30 July 2004 - 12:53 PM

This Valve should be layed horizontally if wanted to use.

Take 2 bottles they should be like the EVIAN or SPRING WATER bottles.

Cut them in half, or a bit more than half.

Take the halves with the bottle opening (the side where you put the cap on).

In one of the halves put a ping pong ball in.

Now glue the 2 halves together backwards , so the 2 cap ends should be pointing outwards.

Duct tape around the center where it is glued to make sure its air tight.

Now attatch a pipe to each end then attatch those pipes to whatever you need and you have a valve where air can only go in, but not out because when its going in the ping pong ball would be rolling a the bottom, but when sucking the air out all the air is force to pull everything out with it so the ping pong ball flies to the end and blocks the cap part where the hose is connected.

i'm making a picture now.
EDIT: Picture (blueprint) This was built before.

Stefan Dart Maker

30 July 2004 - 09:51 AM

After some reviews of Red Foam from Cxwq, he clearly stated that making Darts with Red Foam can be a more difficult task.

If we can invent some sort of Machine, or small system that can create darts for us, it would be a giant leap in the NERF Community. This may take away the glory of looking at your perfect dome, but in the longterm it may pay off.

This machine would not only help in constructing RED DARTS, but also in normal darts. This task of making stefan darts is pretty time consuming and it can be frustrating for starters because the art of Gluing the dome and making the darts nice and straight can be pretty hard at first.

It would take a long time to learn to make a dart perfectly, so it would have its best performance (ex. cxwq's darts).

We can construct a machine that creates Stefan darts for us, it can slowly pull the FBR into a small tube having a timed Blade that will thrust downwards to cut the Foam perfectly Straight since the blade will be going down through a slit.

This process should look like the FBR coming through a Brass or CPVC pipe with a slit through it. At the end will be a vaccuum (not a cleaning one but an air one that sucks out the air). That will provide the suction needed to move the FBR at a speed that will allow the blade to cut the FBR at a desirable legnth. (the FBR will be fed from a roll, and while coming through the pipe it would straighten.)

After this process it could be taken to a converyor belt and dropped into a basket with holes in it. The basket shakes so that the FBR is forced to fall through the holes in a vertical position, these are picked up by some sort of Carrier of the darts. It would be moved to the Hole and gluing process.

The save power and make the system simple, the holes in the top for the BB's or Fishing Weights will be made by a rotating Screw Driver, or if plans might be changed if this comes a reality, it will just be melted by a timed Hot Metal tip. The screw driver would be rotating in one spot and then carrier would spin and push the darts up 1 by one.

Explanation of the Carrier: It will be a cylindric object with holders on the side where the darts would fall into after the cutting process. It would move aside a few Inches to the gluing. The darts in the holders will be pushed upwards into the holing device (hot tip or screwdriver). It will be pushed up by a small metal rod on beside the metal carrier that is timed. (Ex. Every 4 seconds it would pop up to push on a dart). The metal rod would go back down and wait the time and the dart would fall down on the force of gravity. The carrier would be spinning so all the darts would get the hole in the top.

The carrier stays in the same spot for the BB's. There should be a track for BB's with a small cover at the front so the BB's would not roll down the track before wanted. The cover would be in time with the Rod, and powered by the same motor. So everytime a hole is placed into a Dart, the carrier would turn and the BB on a track that is placed diagnolly downwards would fall into the hole.

The next process is to put a glue dome. The glue gun would be like the metal rod but it is now on top of the Carrier so it can dab downwards and squeeze glue out at a fixed time. (ex. Would come down every 3 seconds, shoot glue out the top for 1 second making a custom glue dome size and then go back up and wait another 3 seconds).

The carrier would stop until the person (nerfer) would remove the darts from the carrier and then press a button which triggers the carrier to move back to the shaking basket to repeat its process.

It should be able to make around 10 darts or depending on the carrier size, in 1 minute. This process would go pretty fast but controlled.

This may happen some day, and I will look forward into making this in Highschool because every year there is a convention where they build stuff and 1\10 people make a robotic arm that does something, so I'll make something like this.

Unless someone else wnats to start this sometime or come up with their own design feel free to help the nerf community!

*NOTE* The size of the machine is undetermined but for sure the legnth or <----> direction of the machine will be much larger than its width (vertically measuring)
