well technically they cock, then rock (if your have a stockclass)
then they rock others as you pull the trigger,
and depending on the amount of players you might have to repeat
then they lock (if you have a safety button)

see I can make simple things complicated.

can I skip the rest of my 5 years of college and have my degree nao plz?
kthx.

lol.

No. That's if he wants to do nothing but make charts all damn day about the "issues" without doing anything about solving a single problem.

On topic, though... as I said before, the OP really needs to examine what they're hoping to gain with this, and focus on that, learn about existing designs, etc. This design, though it may have some slight merit, is a failure and should never be made.

Dyson, as in Dyson vacuum cleaners, however has said that he failed thousands of times before getting right. Failure is fine, as long as you learn from why the design failed.

I just realized that how its set up right now the electro magnet will have to be on all the time and release to fire.

typically on a stock class marker, you have to rock and cock at the same time, or rock then cock.
If you rocked it after you cocked it then you would not have a ball in the chamber; However, if I was playing airshotball, I would play stock class, and the only rocking I would do is the rocking and mowing of muppets.

well i cock it but i dont let go of the pump handle. then i rock the ball in the chamber.

but as to what leafy said..... it has not dawned on me that you would need to have
the electromagnet constantly on while gun is not in use. (idle, gassed up)
goodbye battery life.

or is he planning on running out massive extension cords to the field?

Leafy · 12-15-2008, 03:59 PM

Yeah I did the calc for a spoolie that was just a massive noid in a sence. and I'd go through a car battery ever game. and I made it an unballence spool.

jonotwist · 12-15-2008, 10:02 PM

well extension cords could come in handy.

beyond that I believe a spring, or a bleeding valve to bias the bolt backwars could do the trick, (ala SLG)

this way he could keep it unbalanced.

Leafy · 12-15-2008, 10:03 PM

or make it so that the dump chamber is only filled when the bolt is completely back and make is a spring return sear tripper.

batteries would fry

that would be too easy.

cmon, you're an engineer right?

(i now see that i will have fun after graduation)

I think it would be quite hard to make it so the dump chamber only filled when the bolt was all the way closed. it would also limit the rof quite a bit. but it'd be better than a gun that doesnt work.

HyRoller22 · 12-16-2008, 02:54 PM

This was actually my first gun design...I started the drawings in 2002 and never went anywhere with it. Basically, it takes a lot of battery power(energy) to move the bolt with a solenoid. There are of course many designs which are associated with this general concept of using a large magnet to move the bolt.

You already put the Canadian patent up there....and who knows if he will be defending this one in the future. We just have to wait for more efficient batteries...

Leafy · 12-16-2008, 02:57 PM

good luck with this.

beakerman · 12-16-2008, 04:51 PM

haven't looked at this thread for a while but rocket thought of exactly what I was thinking. Ifhte bulk of the magnetic force is in the magnet itself then all you need is a very weak magnetic field for it to interact with to make things happen--either pushing or pulling. The permanent magnet will be doing the work. The electromagnet will only give it something to act on. This means you can get a way with a very small, low power magnet--along the lines of what the solenoids use and still acheive some pretty high forces.

I'm sure the magnets would be expensive but if you keep the mass of the bolt down to a minimum this should not be very difficult. As for the distance of travel involved you can use a sequuencial field to move things--a series of smaller electromagnetic coils that fire off in sequence and step the bolt a long--this can be done very fast. this of course puts you up against the SP patent on electronic timing but I'm sure there are other ways.

Leafy · 12-16-2008, 04:55 PM

they wouldnt need to go in sequence as long as he had 1 coil around the whole distance of travel of the bolt it would move cause the magnetic field inside what would essentially be a solenoid would be facing in the direction of travel of the bolt the whole distance. I'll draw something up in paint I guess.

Leafy · 12-16-2008, 05:02 PM

Ok so here is what would be happening on the return stroke if he had the wire wrapped around the body of the gun. and the permanent magnet in the bolt with North facing forward. This would cycle the marker backwards with the same force the whole distance. If you just tried to pull from the back you wouldn't get this since the magnetic force is 1/(d^2). but for this not to kill batteries all the time you'd need to make it a sear tripper so the coil didnt have to stay on all the time.

new ion? · 12-17-2008, 12:34 AM

just to add to the confusion of magnets and crap, why couldnt he have another magnet at the very back, keeping the bolt there. wait... i just realized that in order to have this too, he would need an opening force. eg: the opening air on a dm. but then... it would be balanced. ugh why cant ppl just stick with air?

Leafy · 12-17-2008, 09:47 AM

the only way it could work with a magnetic return is what i have posted above. just by the nature of magnets.
