D0096F said:The airsoft idea is unconventional. The amount of parts you'd need to use to sync the design of an airsoft piston, would take a lot of modification to put in. For instance you can't just hook it up to a motor, you'd need a spur gear, in order to let a spring push it back forward (or backwards, which would probably work better), then that gear has to hook up to a series of gears so you can get the right timing rpm. Notto mention the batterry needed to power a spring big enough to push the weighted piston with significant force...
I saw the oscillating motor, or whatever you want to call it, that you were talking about on mythbusters (episode about that dude who supposedly collapsed a building inadvertently with vibrations). If you got on their website, there's a forum where you could find out the model and where to get it.
D0096F said:I don't think you understood my post. The piston enclosure takes up very little room, the rest of the gearbox, and the motor are space hogs. The magazine battery is a good idea though.
You would need the piston enclosure anyway. The reason the gearbox's of any half decent gun is metal is because the piston puts a lot of stress on the shell when it flies forward, putting a weight on the piston, and subsequently a bigger spring to give it enough force is going to put a lot of pressure on whatever the piston is hitting against. Correct me if I'm wrong since I'm a prop building noob, but most of the models people make are resin, bondo, plexiglass etc, right? If you were to strip the upper assembly and just plop a piston into the body, your model wouldn't last long at all.
But alright, if you think you can do it then go for it, I don't think you know what you're talking about though...
D0096F said:Well, you could certainly fit a mini's internals in, but it wouldn't have enough force to give hardly any recoil. The gears would probably strip before they could get a weighted piston to move. But, I suppose you could make a "custom" gearbox by drilling bushings into the walls, and then use a mpeg's internals. I still think it'd be a good idea to leave the piston chamber in, once you can start to feel the recoil, the piston will be hitting with a lot of force. Think of it this way, to get recoil the piston has to move the whole gun, that'll take a lot of force, even more depending on how heavy a material you use.
Yes, i meant fiberglass, my mistake.
For the record (in case you decide to try it out) there are plenty of airsoft guns under $100 with metal gears. Most JG, newer WELL guns, and newer CYMA guns come with metal gears (JG and WELL are the brand names), and the plastic geared boxes, generally don't last very long w/o any modification.
pacbury said:very nice, alot of those parts can be found in old electronics and then de-soldered, i agree though, i have never seen blue led displays for sale over here in the uk.
Gokussj5okazu said:Ya, alot of old electronics have the parts I used since it's just a real simple counter and gate setup. Blue 7-Segs are pretty rare, and expensive, over here as well. Why couldn't the counter have been red or something? Those are a dime a dozen.![]()

yea, just wish they sold them at maplin... i love that shopSinjinsmiley said:Pac I have found a few blue 7 segment displays although I agree that they are quite rare in the UK.
