#30363 Actual Silencer?

#30393 Actual Silencer?
Posted by okto on 05 July 2004 - 01:21 PM in Modifications
reduces noise slightly and eliminates rining, but most of my firing noise is still the 'thwop' of the compressed air behind the dart expanding rapidly out of the muzzle.
my first barrel was ported, and had a PVC sleeve around it that was ported as well in an attempt to bleed the air off, but it didnt do a whole lot.
that barrel was 1" long screwed into the stock LnL barrel to fit the OD of micros, so it clearly had other issues. it was a first mod and an attempt to keep the pneumatics as close to their original condition as possible. ive since taken a hacksaw to them.
ice nine, calm. im not a n00b, just new to this particular board. don't worry.
but thank you for the link.
#30467 Actual Silencer?

so i tried removing the closed-cell and wrapped a sock around the riddled-with-holes CPVC and fired a couple test shots. slight reduction in noise, but not significant :/
so it comes down to finding a good baffling material, i think. logically it has to work: noise caused by rapid expansion of compressed air out the muzzle can be reduced by contained dissipation and deceleration of said air.

and thanks for the dollar.
so, decelerating air...ive been musing. as the dart leaves the muzzle, the air compressed in the barrel expands rapidly outward, as the tail end of the dart will prevent the majority of it from going forward. probably some turbulence from the compressed air in the dart (i hollow mine out nerf-style), but i think that can be mostly ignored. so venting it outward right at the muzzle should reduce the noise by the greatest factor, rather than setting up a pressure wave down the silencer tube. i drilled as many more holes as i think the CPVC can withstand structurally right at the muzzle, but it still doesnt seem to be having a great effect. i wonder if a stepped series of progressively larger tubes, like so:
vents ___ __ _____________________ |_____________ |PVC tube 2 ______| |PVC tube 1 | | | | | muzzle | | | | | ______| | | |____________| | |__ __ ____________________|
etc, so that the inner PVC tube's "muzzle" has room around and behind it for air to expand into and be vented out laterally, et caetera ad infinitum. wrap the whole thing in felt or whatever to muffle it even more.
thoughts?

how many of these airsoft silencer lookalikes are actually designed to dissipate muzzle air? ive seen them too, and its usually just a piece of PVC fitted over the barrel. that actually makes the muzzle blast louder. it confines the air to the cylinder formed by the inside of the PVC, and sets up a pressure wave down the tube, pushing the unmoving air in the tube ahead of it, and usually inducing some harmonic resonance in the tube, similarly to a flute only higher pressure and not sustained.
that wasnt supposed to be a flame, hopefully nobody get their toes stepped on. if so, apologies in advance.

creative development only comes from sharing ideas. like to know what yall think. fire away.

#30647 Actual Silencer?
Posted by okto on 07 July 2004 - 11:25 PM in Modifications
after more experimentation the answer is BIG hole(s) right at the muzzle, with some dissipative material covering them. this has the unforeseen pleasant side effect of increasing my RoF by allowing my to insert a new dart without removing the entire silencer. this reduces the muzzle noise to more of a soft "thwip", and has made it apparent that my job of silencing the internals wasn't as well done as i thought--most of the noise was actually the piston and spring, the muzzle noise was just the most obvious noise.

b. the bottom bit is a buttplate, the edge of your hand rests on it, providing a more comfortable and secure grip.
b2. the other bottom bit (the rounded part sticking out the rear of the grip) is a palm support. as you hold the gun in your right hand, it fits snugly under the base of your thumb, again increasing both comfort and positive retention of the weapon.
c. the silencer is going to be covered, the design you see ther has been scrubbed in favor of one that actually reduces noise, which will have a matte-black sheath over the internals to match the finish of the rest of the gun.
d. SKANK TO THE DEATH.

silence the internals. dampening on EVERYTHING. neoprene on piston face, if you can get FBR onto the spring that would save a lot of noise, FBR around the cylinder, the barrel, the cocking lever, the trigger...all of it. my LnL, while still noisy, is quieter stuffed full of closed-cell plastic products, and is gonna get quieter still if i can figure out how to silence the spring.

#30660 Nerf P90
Posted by okto on 08 July 2004 - 04:34 AM in Homemades
anyway, nerf. are you planning to leave it all pipey, or encase it? cos really, the cachet of the p90 is in its one-piece ergonomically molded frame.
also, have you considered battery-powered solenoid valves to give to semi-auto fire? im not sure how this matters in a single-barrel, magazineless weapon, but it would get rid of the awkward dual-sprayer arrangement and give you much more precise bursts of air.

#30668 Actual Silencer?
Posted by okto on 08 July 2004 - 05:27 AM in Modifications
nooooo! it needs to be quieter!maybe your gun, has infact, reached its most silent form *DUN-DUN-DUHHHNNNN*
anyway, as it stands i have a 6" length of 1/2" CPVC, with a 2.5" x 3/4" slot cut in right at the muzzle, and a piece of pipe insulation over the lot. from holding the gun and firing it, all i her is spring noise, no pop.
so next step is i'm replacing the piston and cocking lever with something stronger, to minimize breakage (and allow me to adopt a design more suited to silencing), reinforce the spring retention wall, get a bigger spring, and rebarrel.
so basically, the totally unnecessary portion is done, and now i only have to do all the important bits

should i go ahead and knock out the regulator spikes, is there anything to lose in doing that?
#30766 Actual Silencer?

in this particular case the internals are still too loud to make the silencer an effective component, but it does work; the muzzle blast is no longer audible (and it was pretty loud)

personal note: i think the cut-down 'luger-esque' NF's are ugly as sin. give me a good rectangular, flat-fronted gun anyday. stronger, too.

#30812 Rf20 System Mod?
Posted by okto on 09 July 2004 - 03:11 PM in Modifications
im not banding my freaking gun. not this one, not any of them. none of the parts were meant to take the additional lateral stress and thye will break.
bladder mod...hm. if the interconnecting tubes pop or come off, its not that big a deal since they all have threaded compression fittings, and its standard clear tubing. i wonder if the fittings would need to be upgraded to deal with the higher pressure.
