How about the best name for this mechanism? Make your suggestion!

[@MariusKvia]

if it was a handgun it could be called Block18

Flywheel railgun? cause it still technically has rails.

[@davidziemkiewicz1350]

Consider supporting the wheel axles at the top and getting rid of the red indicatiors - these things cause a lot of wobble, greatly reducing speed. With lego axles, you can get to around 6000 rpm (100 rotations per second) before they melt from friction. Believe me, I tried XD

[@DrEngine]

Thanks, nice suggestions!

[@derpco.69420]

Bro ICBL

[@papawheely3627]

Did you try lubricating the axles to reduce friction? It may be possible to get them going even faster.

[@davidziemkiewicz1350]

@@papawheely3627 Yes, silicone based lubricants work well. On Brick Experiment Channel, there is a video of a small wheel spinning at 24000 rpm with it.

[@warbrain1053]

@@DrEngine i also think that for the reloading mecanism, a different wheel position, or making a bigger first wheel would make the fire rate higher too. Also make it a portable version with a magazine and a trigger to fire xP

I was doubting the "incredible accuracy" until at 2:24 when the second bolt went through the first bullet hole without touching the sides

[@MemeBurger]

So... is it a railgun? The law requires me to answer "no"

Elon?

No railguns fire high velocity projectiles via electromagnetic currents

@Tony Stark he could make it operate on a crank system

[@pablobartelotte4553]

It's the same as a pitching machine, baseballs and tennisballs. Now make one with 2 chainsaw motors and trailer tires. I bet you could throw a 2x4 couple hundred feet.

Here is the bulding instruction for Lego Brick Thrower Machine AKA “NOT-A-RAILGUN” doctorengine.info/?p=243

[@typehere6689]

A similar mechanism can be found in some ball yeeting machines and foam dart projectors.

[@Demonanimator]

Right? This is basically a flywheel foam blaster

[@kolvis6626]

*nerf stryfe sweating nervously*

[@OatmealDonk]

Can confirm: dismantled my nerf gun (large motorized one with a magazine. It's blue if that helps? XD) and found this exact setup, only with extra steps for safety.

[@typehere6689]

That answers little considering that there are four projectors that fit this description.

[@cursednerfblasters1244]

[@parlor3115]

I feel that the penetration testing against a bunch of translucent membranes might be a metaphor for something.

[@ashleyedwards9523]

I'd love to see the wheels running on the same input rotation as the loader! Maybe some kind of reduction system?

[@DrEngine]

May be, nice suggestion, thanks!

[@digitalh3lmet]

For those, who are really interested, music is Coma Svesson - Bright Red Lights (Instrumental)

[@mojolotz]

I recommend coupling the two wheels for even more accuracy. This leaves room for one of the motors to spin slightly slower or faster.

[@DrEngine]

Two wheels in a row on each side?

[@mojolotz]

​@@DrEngine No i meant the two sides. If one side spins at a slightly different speed than the other side, it might give the projectile a spin on exit. If you connect the two sides, so that they can functionally only spin at the same speed, that cannot happen. I don't know how precise lego motors are and wether this is a problem. You've got a tachometer, so you can test this i imagine. I think more wheels would only do something if the projectile slows down the existing whells sufficiently. I think adding more weight onto the axes (sort of like a flywheel) would do the same thing.

[@markmascadri1342]

So while the kicker design you use works have you considered using a cam? I made a frisbee launcher that used a cam to great success.

[@newmoonwithface]

Drum magazines or some higher capacity mags would be cool to see!

[@bricktonmcbricks3969]

I'm not a lego technic guy but I don't think drums are possible to make with lego

[@Attrixine]

@@bricktonmcbricks3969 Unless you somehow had springs capable of usage with lego, it’s not possible as drum magazines use springs or some other winding mechanism to feed the rounds, Although for some machine guns like the MG3 and RPD, the drum only contains a belt already feeding into the mechanism, so it doesn’t take any springs.

[@bricktonmcbricks3969]

@@Attrixine yea that's exactly what I was worrying about. As you said in order for a drum mag to work you need a spring mechanism. Thanks

brilliant work

[@myteethhaveeyes]

I got so fricken excited seeing that magazine, idk if they’ve used this design before but that is clever af

[@tyger449]

I think you could find a way to reduce the bouncing and recoil. I think that's why the first few are clean and straight and proceed to get worse as the magazine empties.

What about using bigger broader wheels, angeled slightly opposite to each other to generate rotation, and shooting black rods, maybe with a nail into front of rod to add weight

I was thinking of this trick for GBC perhaps shooting the balls in a semi-tunnel or half-loop instead of the quirky traverses they use to cross the walking lanes in the exhibition halls.

[@igkslife]

Now imagine a satellite based off of this design, but not using legos. With a rail gun on the end of the barrel, or as the barrel. Targeting my enemies from space. This theoretical weapon is theorized ( note: not by me) to have the same destructive power as nukes. The theoretical weapon is called rails of god, or rods of god, or something like that. ( note2: I must stress, I did not come up with the idea, but I wouldn't mind owning one.)
