What is the range of a well-built small(ish) coilgun?

Depends on how well made.

Google something like "disposable camera spy coil gun BB".

There is a site out there that will sell you plans to convert a disposable camera into a "spy" coil gun that fires BBs. The barrel is hidden in the camera and the muzzle is where the camera's lens was. They have a video showing the "camera" shooting a BB and knocking over a Scrotch tape dispenser at a range of 2 or 3 feet.

Oh yes, I've seen that before. Its pathetic. I think I'll stick to my pneumatics

[TwitchTheAussie]

W00t for pneumatics. Yeah Im building a small pneumatic in metal work. My maths teachers afraid of me and sadly everyones scared of me losing my temper (for a good reason). Its funny shes no porn start but shes alright But for now taser

[spud yeti]

Thats so cool. Yeah, in art Im planning a fat exhibition for final year that involves spudguns, its going to be insane. When I exhibit I will post a topic though.
Everyone in my grade has this "respect" for me because I have massive arm muscles (which arent actually that strong, but look great!) because I cycle, so they just pop out; and I build spudguns!

[TwitchTheAussie]

lol I got no muscle what so ever. I think its just the fact that when I once lost it I almost stabbed a kid

[wannabie]

lol you guys are just abit crazy... although these two kids were shooting spit balls at me for the whole of maths class so i thought of a way to get back at them.... im in the process (sp?) of making a hot glue piston for 3/4" pipe

BTW nice job on the catapault

[spud yeti]

Hahaha, with what? When I get mad I usually go real calm.... Then BAM! (he didnt even know what hit him!) But Im usually quite calm and dont hurt people (note the "usually" )

[wannabie]

lol. you meen what were they shooting the spit balls with? just pen tubes...

[spud yeti]

I was meaning what did Twich try stab the dude with, but its all good. That piston gun sounds pretty awesome though, how far are you with it?

[wannabie]

How far am I.... hmmm i have made the piston, have the barrel, have the schrader valve, pilot valve. Not the chamber and mabye some other things i dont have which i forgot.... but im not sure if ill take it to school because if i get caught with it i would get like suspended or expeled

[spud yeti]

Ja, I wouldnt, its not worth the risk. Thats why I took the catapult, because its less serious or "gun-like". Are you going to make it a coaxial?

[wannabie]

yeah a coaxle is what im aiming for but I might make it in a T i'll have to see what the have at the hardware tommorow.

[spud yeti]

LOL, yeah. I like both coaxials and T's, but I'd have to sway towards coaxial on this gun because of it's small(ish) barrel... although a T would be cool too... Which do you prefer?

[wannabie]

well i prefer coaxials because i have only made one piston gun and it was a coaxle and i think they are more compact.
