thanks yes my budget isn't huge but I think I will manage to buy a pretty strong engine and I already found some cheap rope. and is there a big difference in power between a clutch and a simple chain ? I would like to start pretty soon since the temperature is raising over here what would you see as...

hey, I am probably going to make a winch for wakeboarding this summer but I still need some problems to be solved. first an impression of my idea http://www.youtube.com/watch?v=J1PN7he_MOw i am planning to make something along the lines of this but what kind of engine will I need ? I don't think 50c...

bumper: depends on the material of the piston
if it is e.g. hot glue there is no bumper needed but for a piston made from wood I would recommend it
lubricant: very usefull because it makes the piston move more smoothly and quicker
it also helps to seal
pressure: I used a hot glue piston on 40 bar

I made this valve already for a pneumatic

try inonickname's idea
I think there is too much air coming out of the barrel behind the pellet giving it an unstable flight

with a hammer valve you can get plenty of shots

why not make a kind of revolver? hammer valve hit by a hammer like in a real revolver and somekind of revolving magazine

good job
I used to shoot these out of a piece of pvc

try and make a vid of rolling one

I love it!

are there more specifications of the gun ?

that's looks amazing!
barrel?! that's really cool 8)
is it possible to make the hopper in the polycarbonate block?
I love it to see all different things move when a gun shoots.

design it like a paintball gun
the chamber diagonaly and the small chamber as a grip

I like your thinking!

hahahaahaha
maybe a little crazy
but it's very cool 8)

it just are some points
you an buy virtual stuff with it in the store
things like a signature are sold there

did you search?

good work

you could make a pump action reload system
just cut out a square out of the pipe where now the ballvalve is
then slide a pipe over it and a pice of pipe over the chamber
connect those pipes and TADA!

WOW
this is like pilot............................................fire

I actually started qev + popoff too and with 180psi it still is a short burst of prrrrrrr out of a 600cubic cL chamber to supply and
thats with an 1/8" qev! and a very small air chamber.
