Screw the springs... I want magnets!

[Lenny]

How hard would it be to replace the bolt spring with a pair of magnets? I figure it'd make the operation a wee bit smoother, as well as add something custom to my gun.

I could drill and adhere them pretty easily (actually, might not even have to adhere them seeing as though they repel), I figure, but I need to know where I could get magnets that'd work for this, how I would insulate them (so the entire body doesn't become charged), the tension needed, and how much space I would have (or the length of the spring coiled during a firing sequence).

Can anyone help me out? Thanks.

the nice thing about springs is their force output is (more or less) a linear relationship. It takes "x" number of pounds per inch traversed.
---> F=k*x where F is force, k is the spring's constant, and x is the distance

The force to move opposing (or attracting) magnets is "quadratic". In other words... the force between 2 magnets is proportional to the square of the distance.
---> F::x^2 where F is the force, X is the the distance that is squared, and "::" implies a relationsip charactarized by a multiplicative constant.

Basically, it could be done... the magnets would need to be rediculously strong, magnets lose domian alignment with multiple shocks applied to them (lose magnetism), they can induce a current when cycled quickly near aluminum, and are all areound not worth the effort to replace a $.05 spring.

But yes, it would be cool and might be smooth if actually pulled off.
Are you talking about replacing the mag bolt spring with a magnet

lenny, i think you just got AOWNED.

ok so to get the useful (or at least hopefuly useful) replies back to at least 50%

what might work, since the magnets can wear out, is to use electro magnets.

the only problem i can see with useing magnets in a mag (assuming thats what we are talking about) is that since the whole bolt is steel it might not repel correctly (since you will prbably have the half of the bolt infront of the magnet and the other half behind)

its a cool idea and could probably work in one way or another but it would take a lot of R&D

electromagnets might work..... if you wanna wear a bettery pack the size of a Ghostbuster proton beam pack.

How could you drill the magnet without shattering it?

[Pneumagger]

Use EDM? Assuming it's conductive

[sniper1rfa]

That would work. Neodymium is a rare-earth metal, so i assume it is conductive.

I don't know about the compounds used for magnets, though. It's usually neo, iron, and boron according to wikipedia. Probably conductive.

It's: Dont cross the STREAMS!

duh...

Wow... denied...

Ok, so creativity doesn't always equal intelligent...

Dang. I though it'd be so cool, though. And Joe, thanks for the math lesson. That's just one more thing they never taught(sp?) me in school.

Oh well... Thanks guys.
