Actually that's not a bad idea if you can't work out a sear mechanism like JSR has.

(And for JSR, no it shouldn't, look again and you'll see the idea is that as you pull back on the trigger it pulls the hammer back stretching the spring, to the point that the tension on the spring overcomes the attraction of the magnets, at which point the hammer is released and viola, pop, bang, whoosh it fires.

Neat idea and it even gets round one of the potential porblems of a lower-pressured, hammer-valved gun, that of leaks. There's no reason why the hammer half couldn't be inside the "pressure vessel" and the trigger/sear half outside it.

Right, I though the magnets were repelling eachother

Oh perhaps they are?

Well if they are that's a silly idea and my idea is much much better to have them attracting each other, and it's all my idea and I got there first.

So there.

EDIT: Nope they're attracting each other, which is a good thing, and could give a nice semi-auto hammer.

In fact combine it with a similar idea for a breech and you've got a beautiful little semi.

No, the way i thought of it was to attract. The magnets my friend had made may actually be too strong to be pulled by the trigger. he made them yesterday, and they are pretty darn strong. how large of a spring is neccesary to knock open a hammer valve? It would seem that once a spring is large enough for power, the trigger pull would be enormous. Any thoughts?
