the drawing is not so good but hope you understand.
i drawed it in paint :P

Step 2: The Parts

Picture of The Parts

You can get all the parts at almost any harware store or local supply.
The airpiston is from a bike pump and the spring is from an umbrella.
The parts in trigger mecanism i made from a metal pipe. The metal pipe in the trigger is alos from a umbrella.
I used no big power powertols like ( lathe or mill), but i had a grinder but you dont realy need it.

Step 3: This Is How It Fits to Together.

Step 4: The Trigger Mechanism

the trigger mecanism is as simple as it can get, and it worked verywell.
i was supose to use a spring in the trigger mechansim but did not find one so i used a rubber band:)

Step 5: End

sorry if i provided to little info i did not think of making a instructable when i started building ( infact i did not know about instructable)

Using bike pump as the piston is a very good idea, I have no idea why I haven't thought about it, I've been thinking how can I make a well sealed piston out of nothing lol, cheers for the idea! And I'd very much appreciate some further details and maybe info about the new version. Keep it up!

hey can you help me was the bike pump like a foot pump or one of those tube like ones. also where is the spring in the umbrella !
please help !!!

it's the small tubelike pump:) and the spring is in most automatic umbrellas, the spring is easy to locate if you have the right umbrella

Great idea, I have designed a similar paintball shooting one like this "I have in fact made a Google sketchup model of it so if you have Google sketchup have a look at "homemade spring paintball gun" on the 3d warehouse, its pretty cool) but the idea never got off the ground as I never had a powerful enough spring.

cool, wil take a look at your gun!
you can actually find very strong springs in some type of umbrellas. that's where I had got mine from.

how do you load the bb, through the barrel?


sabladask (author)thyyt12011-03-24

I used a stick to push the bb down ..lol:)
,but i have made a new softgun whit a magazine that charges itself.

thyyt1 (author)sabladask2011-03-28

you should chuck a picture up, i have an idea to make a mag that reloads when you cock the spring, i haven't made it but i think i will when i get a chance

Really nice! If you ever build another one it would be great to get more details on this. Regardless, thanks for sharing!
