it's not very sturdy, but it is a good idea.

You know fps stands for feet per second and is a measure of speed not distance =P

shieldsam in reply to Fred the PenguinOct 16, 2010. 1:50 AM

i thought fps was frames per second on computer screens and stuff

tytnium (author) in reply to Fred the PenguinApr 14, 2009. 4:49 AM

yes, I am aware of this. i want to let any potential builder know that this is not the strongest of guns, and chose to use speed instead of range.

Fred the Penguin in reply to tytniumApr 14, 2009. 3:01 PM

You know 50 feet per second is pretty fast its something like 60kph or 40mph which I'm not sure how you measured

ashchetm in reply to Fred the PenguinOct 10, 2009. 9:07 PM

I measure by shooting at a wall, or anything that makes a noise for that matter, and keep changing the distance untill it takes one second to hear the noise of it hitting, then measuring out that distance, for instance, my killerk magnum shoots at 65fps. I did this by shooting the gerage door, and well, you can figure out the rest. (yes I am aware your post is sevral months old now)

LOL, I just singned up to say that the guns u guys make are cool but some of you are way to upsessed, you all need to find somthing else to do with your spare time (and this is coming from a 13 year-old)

Oompa-Loompa in reply to h20incineratJul 15, 2008. 7:50 PM

This is coming from a 14 year old. This may be an obsessive hobby, but it's good for your creative thinking.

Pokezamer in reply to Oompa-LoompaNov 26, 2008. 12:07 PM

yes, yes it is. knex is the best creative thinking improver!

jli1 says: Dec 13, 2007. 2:36 PM

doubt it can shoot 50 fps

popomaster in reply to jli1Mar 30, 2008. 8:24 PM

50 fps isnt that fast just to let you know.

xctcxzeroshot says: Jan 8, 2008. 8:20 PM

I liked it but doesnt shoot very far maybe ehhhhhhhh.. 27ft.... but over all nice pics simple cool gun

guillermo433 says: Dec 10, 2007. 8:49 AM

thats a funny gun man!

F-zero says: Jul 8, 2007. 3:41 AM

This is fun, I put double rubber bands on the firing pin and add more pieces past the safety for extra stability. I didn't have many single greys available so i just used orange connectors. I like the trigger system, much better than I could have done, haha.

CALM DOWN!!!!!!!!!!!!!!!!!! if you are not interested in contributing to the knex section of the site then just go away and knex is not for 'kids' it is a enigineering product that is safe and fun to use. so if you dont want to join in the fun but instead moan then do what ever you want to do and leave use to enjoy ourselves

ash1494 in reply to Loosewire; SOE OperativeJun 6, 2007. 3:32 PM
