So I was wondering what the best method of propelling something like, oh I don't know, a hot dog. I was thinking compressed gas but I'm open to other ideas.

Water Rocket Launchers

Water rockets are fairly new to water warrior technology. To reduce our carbon footprint, water rockets are built using plastic bottles. This forum topic talks about the operation of standard water rockets and launchers, how they can be used in a water war, construction of water rocket launchers, rockets, and add-ons like water balloons on the tips of rockets, ammo clips, and grips as well.

Calculating Drag When Firing Potato Launcher and Design Specifications

I'm interested in making a pneumatic potato launcher, I've found plenty information on that but I want to hit a target 255 meters away at an angle of 45 degrees. I calculated that I would need an initial velocity of approximately 50 m/s without wind resistance. The object being launched is an average sized potato under normal weather conditions. With wind resistance, what initial velocity will be required to hit the target? Please explain the process by which you came to the answer so that I may use the same method in future endeavors with different angles and distances. Also, just how much pressure would be required to launch a potato and achieve that speed, and to what specifications would the launcher need to be built i.e. how large the gas chamber will need to be, length of barrel, etc...

knex large gun help

Problem-i am building a large knex bazooka that needs a customized firing system. it needs to hold on to the projectile with some sort of fingers, which are to release when triggered from the rear of the holder, and the holder needs to ride in the rails of the gun, and it needs to be able to attach to a length of string. operation is-latch projectile in claws, pull both claw and projectile into barrel, pull to rear of barrel, stop motor, pull trigger, which through a series of levers will push to release on the back of the claw, launching the projectile. can anyone create such a claw as im stuck. ive got the gun, motor, gears, and projectiles, but i need some claw befor i build the trigger so they'll be compatible.

Asked by Dave6 7 years ago

I was watching the military channel, and I saw the M32 grenade launcher. I really want to build something like it with knex. But here's the problem: I have yet to find a grenade that can fit in some sort of barrel. I'd use Carlz's grenade, but the rubberbands on the outside of it would GREATLY decrease the range. We need to make a smooth grenade, any ideas?

Trip USB Missle Launcher

Hello everyone this is an idea i had and i am going to try and do. The idea is to take one of the Wireless USB Missile launchers(seen here: http://www.newegg.com/Product/Product.aspx?Item=N82E16800997039) and connected it in some way to one of the trip bells(often seen at stores). Instead of setting the bell/alarm off i want it to send the singal to the USB Launcher and have it shoot at a set location.If anyone can help direct me as to what i need to buy and do to make this work all help would be appreciated.

Will this launcher design work?

Concept - A hybrid-launcher (combustion and pneumatics) with interchangeable barrels for various projectile types So the design is pretty simple, in the back of the gun launcher thing (we’ll call it ‘the weapon’ for now) will be a propellant chamber measuring 2.5” wide and 1.5’ long. On one end of the propellant chamber will be an unscrewable coupler. On the other end, a 2.5” ball valve. Attached to the ball valve will be the female end of a 2.5” coupler (without cap) From here will be the interchangeable barrels, which are simple. The barrels would consist of the male end of the 2.5” coupler and a 2.5” width converter, converting the width from 2.5" to various different sizes for the different projectile sizes (this would have to be one piece for durability, idk if such a piece exists, I hope it does, if not, i can make one) the barrel itself would measure 3’ in length A Shrater valve (bike tire valve) will be installed on the propellant chamber (for pneumatic power). A bike pump would be mounted on the weapon (like a shotgun kinda) An ignitor will be installed on the back of the chamber, mounted on the unscrewable coupler.

how do you build a grenade launcer?

It looks like a short sholder mounted rocket launcher only it takes the big co2 canisters, fires those nerf footballs that have tails, and loads from the top by cocking the front barrel forward and loading the round into the barrel before snapping it back. It was in a video on youtube.
