Hmmm, Rotary syle bolt?

how can anyone say that a 2.3 lt encine making 255 hp has efficincy

come ppl dont just talk out ur @ss

the rotary engine give you the most for the least.

ignorance kills

Even more impressive is the rotary in the new RX-8. 1.8 liters and ~250hp....that's pretty impressive...rotaries have always been efficient, just not very reliable...

[flanders]

reliable as an engine or not

as a piantball design it's very impracticle except for stock class it could be kinda cool. may be

Dudes,

I see a rotary type bolt in a paintball gun having lots of advantages over the norm thats out right now.

First off, It's going to be much easier to rotate this bolt as opposed to one that moves back and forth. As long as there wasn't too much friction between the body and bolt, seems to me you could run the pressure turning the bolt verylow.

After the bolt has rotated in place, the gas propelling the ball out the barrel isn't also going to push the bolt backward, causeing blowback, like it does in guns today.

It could be pretty darn compact, depending on how everything works.

One other MAJOR advantage, would be, if you had a big enough bolt, you could have 2 slots for the balls to feed. While one ball is shooting, the other is loading simitanously. 18 BPS on that HALO? Couldn't this sucker feed 36? That is of course, if the bolt could cycle that fast. (I think my reasoning there is correct)

The marker would also have a different kind of kick. I would think much less than other guns, but I'm not really sure on this one. Low pressure, and you could also have a light bolt, since you dont need the extra weight to help hit open a valve.

Integrating a spool valve into the bolt would be real nifty, but I think it would be hard to get it to work right with the seals.

I could see sealing the bolt to be a bit of a problem. And also machining the gun could be tough. You would have several ways of spinning the bolt. Other then that, I don't see why the gun wouldn't work well.

P.S. Is it just me, or are some of these gun manufactors not too bright? I mean we've got what? 5 copies of the angel/timmy/impulse/viking/tribal style gun? Geeze.

well in are gun there are 8 slots. so one being feed one feed one fireing. the bolt pressure doent matter cause if u pinch it stay pinched the bolt only move one way. that why we are going to elips the top part to funnel it in to the bolt. plus the part of turning htebolt the exact degrees in a shot fast burst is difficult.

Thorpydo, have you been talking with andy? (warpedmephisto)

and no the rotating bolt is no problem to machine

but thats a no on the dual feeding, think the thing has to rotate 90 deg.

and is 6" compact enough

[Thorpydo]

Rich,

Yeah, I got warpedmophisto on my buddy list. We talk some. Why?

My dad thought up the rotary design; Didn't get the idea from online or someother spot. He really thinks that it would work well.

[ME262]

well, just everything you stated is somthing we're working on
for about a year now its been bouncing around in the shop here. finally close to finishing the bolt system

[Thorpydo]

Really,

Don't believe I talked with him about any details of the gun... Just that he was in the proccess of making one.

The design has alot of potential. Alot! Would be really nifty if you got it working with a spool valve.

I would certantly be a fan =)

Oh BTW, I don't see the advantage of having any more slots than two. Seems like having 8 would just make it bigger. Anyone got any ideas?

[diesel4mee]

are bolt is 3 inches. the 8 slots are just so we have a fast cycle rate.

[Thorpydo]

3 inch diameter? Thats pretty big..

I still don't see anything over 2 slots effect ROF or cycle speed, unless your just referring to haveing more balls sorted at one time.

[Thorpydo]

After I posted that, I think I saw the light.

Are you talking about the distance the bolt has to spin?

[diesel4mee]

yes

[akagotcha]

hmm

ive been here from time to time looking at this post and have been thinking what would stop this thing from being a blender. there would have to alot of timing and such or a really durable parts. think you have to get a ball to drop into the slot have the rotary bolt spin, propel the ball forward and have the bolt stop in fractions of a second. another question i have that has been bothering me under rapid fire what would prevent the gun from chopping all of your paint.

alright time for the improvement thoughts as for the back spin you could use a barel system which would be the kinda oposet of the flatline to get rid of the back spin

just me two sence

hey we have are gun as and electro. so the time is no problem. the problem with the paint being feed and shot. there are 8 chambers. 5 are dead in the cycle phase. let look at this like a clock. one is at 12 the one feeding of jsut been feed. second bettwen 1 and 2 already feed not at fire postion. 3 being at 3 the fireig position. so when u fire the gun fire the ball at 3 then rotates 45*. move each slot or chamber respectivly. we have a anti chop funtine in the making if there need to be one but with two seperte chamber fire cycle is the same as loading so there should be no problems.
