Today I got bored after my new marble gun wouldn't pilot on a modded blowgun, only ~1 cu. in. of air and it still wouldn't pilot! Also my mapp gas torch wouldnt ignite so there went my cardboard tube golfball gun....

So anyways here's what I came up with...

Guts are secured by masking tape, hidden by electrical tape...

The Other side...Notice the metal rod to secure the break barrel.
Image
A size comparison...
Image
Break barrel!... breech loading and easy venting...
Image
Ready to shoot!....

Specs:
Onboard butane
Piezo ignition
10" Barrel from an aluminum knitting needle. Colored pencils fit great :D .
Chamber is a vitamin c bottle..
Break barrel is secured by a small metal plate with sliding rod....

Sorry for the crap pics, used my phone again :x

Thanks :D . I would have included a vid but my dad got all mad cause I fired giant spitwad out of it and somehow plugged up the barrel, popping the lid off. = Really loud noise :lol: + its fire in the house... Oh and this was before I installed the metal rod and plate to secure the lid.

Haha yea, BTW if I had a 1ft distance between photocells and i got a time of .63 between the spikes would that be 630 FPS? Im kinda confused, multitasking for a long time takes its toll on my brain :? .

well if you had what you said, and the time is .63 *seconds* you would have a velocity of 1.587fps..LOL velocity is distance over time. so 1 foot divided by your number of seconds.

i added you on msn and aim

Wow that's cheap, uhhh, in a good way. Reminds me of my vortex trial (trial because it doesn't count, looks too horrible). Very MacGuyver lol.

Its cool but it belongs in the mini section. You should turn it into a coaxial, thats what i did to my mini and it worked better and its more mobile.
