Big Nerf Bazooka Packs A Wallop

November 20, 2020 by Lewin Day 4 Comments

Nerf blasters are a fun toy, often confiscated from children once they hit one too many precious ornaments around the home in the midst of battle. [Ivan Miranda] is bigger than most children however, and set about building a much larger blaster.

The bazooka-like design uses a several meters of 160mm PVC pipe, firing “darts” constructed out of foam yoga rollers and buffing pads. The build uses a littany of 3D printed components in its construction, both as part of the firing mechanism and as jigs to help machine the pipe. A large plunger is used to propel the darts, which is pulled back against the tension of thick rubber tubes before being released by the trigger mechanism.

It’s an intimidating device, to be sure. However, we suspect its short range, huge size, and slow reload time should stop it from breaking the meta-game at your local Nerf battles. That said, we still wouldn’t want to take a shot from this bad boy to the head. Hackers do love a good Nerf build, and they’re particularly popular in sentry applications. Video after the break.

Vacuum Pressure Bazooka

August 24, 2013 by Mike Szczys 39 Comments

This vacuum pressure cannon is a design unlike any we’ve seen before. At first look it seems to have the components you see in a potato gun. But those use a combustion process to launch the projectile. This instead uses the sudden release of a vacuum.

About three minutes into the demo video below we get a look at the “ignition” system. It’s pretty scary in that a couple of really powerful springs are pulling a collar along the barrel toward your face. This is actually meant to dislodge the plug in the back which is holding vacuum in the barrel. The pressure difference causes a sudden inrush of air which shoots the 1.5 inch projectile out the front of the bazooka.

[Mr. Teslonian] built his own hand powered vacuum pump for loading the weapon. This was done with a pair of PVC pipes that fit inside of one another, and a plunger made from wood and leather. The PVC and wood projectile seals in the barrel using a skirt made from duct tape. After breech loading the projectile and plugging the back of the barrel, he layers aluminum foil over the business end and pumps up a high vacuum. His test firing is not from the shoulder, and he only gets one shot because the slug hit the target so hard it was destroyed. This thing really needs to be vehicle mounted!

Surplus Bazooka Converted To Shoot Firework Artillery Shells

[Mark] and his friends love fireworks, but got tired of the traditional ground-launched mortar rounds, so they decided to spice things up a bit.

A while back he purchased an Army-issue bazooka at a gun show but didn’t use it for much, so it sat unused for about 10 years. He dug it out of storage, then hit up his local hardware store for a few lengths of PVC piping. He cut the pipes to size and then used his 3D printer to build a couple of parts to securely mount the PVC pipe into the bazooka’s shell. With his standard tube, he can shoot 2” mortars from the bazooka, but says he can add a second nested length of PVC to allow for smaller rounds.

Obviously this sort of setup can be quite dangerous if it is mistaken for actual weaponry, or if your fireworks were purchased from some guy’s trunk at a highway rest stop. [Mark] and his friends have taken some precautions when they use the launcher, but this is still clearly a risky enterprise.

That said, we think its awesome, and if anyone has a spare bazooka sitting around, feel free to send it our way!

[Correction]
Not a bazooka, it’s an AT-4. Thanks to those who pointed it out.
