semi automatic knex pistol

$G:\DCIM\100MSDCF\DSC00392.JPG$

this is it! the first ever true trigger semi automatic bottom loading magazine pistol.i was playing around with different mechanisims of how to make a semi auto like having the trigger pull back the ram but this did not work so i moved on to a multiple rubberband system and how a rbg could be adapted and this is what i found...

Copy and paste the picture into some picture editting program to see it.

I built it, it was kind of inaccurate, slow reload, but the handle (when changed around a tiny bit) was SO FREAKING COMFY :D I'm going to have to change it around to just be an rbg and use it for the kick-butt handle. Overall...4* :)

it takes way to long to reload you need to make that better

I have retired from making K'nex guns now...I'll leave that for someone else to do :P.

I modded this a bit, so its like a table-top cannon. When you press down on the top, it fires and then it springs back up again. Semi auto of course. If I post it, I'll give you 77% credit.

bedbugg2 (author) in reply to j-chode!Aug 6, 2008. 8:26 AM

ok, post away!

j-chode! in reply to bedbugg2Aug 8, 2008. 1:14 PM

It is up, but only as a slideshow as my brother dis-mantled it.

The Jamalam in reply to j-chode!Feb 19, 2009. 6:41 AM

why did he take it apart?

DJ Radio in reply to The JamalamOct 8, 2009. 8:25 PM

He was probably a jerk.

PieMaster777 in reply to PieMaster777Aug 24, 2009. 12:34 PM

srry thought it was rbg cant see why though...used to be a noob...

bedbugg2 (author) in reply to PieMaster777Feb 8, 2008. 8:56 AM

what? lol...

dsman195276 in reply to bedbugg2Feb 11, 2008. 8:18 AM

he probely is a NOOB that did not look through the instructable and just thought it was a RBG.

aikduck says: Jul 11, 2009. 4:43 AM

i've experimented with having a full auto knex using the rbg style mechanism but the rubber bands all shoot before the bullets can be reloaded by the magazine. How do i slow the mechanism down that releases the rubberbands?

bedbugg2 (author) in reply to aikduckJul 12, 2009. 2:13 AM

Yeah, i came into the same problem when i tried to make mine fully automatic...the only solution i could think of would to be to use some kind of geared mechanism to slow down the rubber bands.

Miles Tails Prower says: Feb 23, 2009. 4:06 AM

I made something similar...

BUT!!!! before you say it is better, this one is made first so it is better. Very good work. 4.5 stars!!!

bedbugg2 (author) in reply to Miles Tails ProwerJul 12, 2009. 2:12 AM

Wow! that really is something...much better than my design, you should post it.

the_builder in reply to Miles Tails ProwerApr 6, 2009. 6:18 PM

You have to post that gun. It is amazing!

Miles Tails Prower in reply to the_builderApr 7, 2009. 7:21 AM

Thank you!!! But I'm VERY lazy, I mostly don't post instructions...

the_builder in reply to Miles Tails ProwerApr 8, 2009. 8:11 AM

Wait, I did notice that you do post videos of instructions, so would you be willing to do that? I you just do want to, thats fine. It doesn't make a difference to me!

Miles Tails Prower in reply to the_builderApr 8, 2009. 9:06 AM

Yup, I'll try my best for you.

the_builder in reply to Miles Tails ProwerApr 7, 2009. 8:14 PM

Awwwwwww... Darn! =)

therandomperson in reply to Miles Tails ProwerApr 6, 2009. 6:30 AM

actually, ive done my take-on of your gun. ill post pics soon

yerjoking says: Jun 7, 2008. 4:59 AM

i gots a problem, after a couple of shots a bullet falls out, am i using too powerful elasticbands?

Wafflicious in reply to yerjokingJan 17, 2009. 7:58 AM

Most likely too powerful on the mag.

DTass says: Jan 9, 2009. 1:20 PM

Thanks bedbugg2, the gun shoots well

DTass says: Jan 8, 2009. 2:03 PM

I have the gun built, but I don't understand where to put the green bullets.

bedbugg2 (author) in reply to DTassJan 9, 2009. 8:27 AM

you put them in the magazine, picture 3 on the last step, the part wite lots of white snowflakes. you take the rod out which is held in by the elastic band, drop them in one by one, once you have loaded all 8 you put the rod back in to press them against the sight. just message me agian if you have any more problems :)

bedbugg2 (author) in reply to knexsuperbuilderfreakJan 3, 2009. 11:58 AM

stale56 in reply to bedbugg2Jan 7, 2009. 4:23 PM

how bout me? i have an excelent mech (in my opinion) and i was looking for something so it can shoot rods to (i was to lazy to look at the dunkis's mech and follow it). if u wanna see i have a link to the forums here so can i please base my rod shooting mech off of urs? i will give u credit in any way u want me to. i feel like a complete idiot begging u for this...

knexsuperbuilderfreak in reply to bedbugg2Jan 3, 2009. 12:31 PM

ok thanks

Ikedog1995 says: Jul 31, 2008. 9:43 AM

should i post? pros: Powerful (40 to 50 feet), cool looking scope, doesnt mis-fire, simple knex gun cons: looks bad and slow reload ( but not too slow)
