DIY LDC

[rex]

LDC-is lead dust collector.It does collect lead dust but as well buffles or decreases the sound made by your gun.Here in PI it is safe to call it suppressor/silencer.

Been out of the forum fo quite a while,been busy making LDC for my PCPs to make it backyard/neighbor friendly.I finished the one for my new AG but having difficulty with the Discovery,could have just bought those fancy LDC online but with the materials at hand I took the challenge of doing it.
With just an inch of the barrel to work on and no lathe machine took me five prototypes before settling for this one. 60% sound reduction.

thumbs up bro.

hi bro rex

can you give me idea what's inside of that LDC or silencer? its good that it reduces 60% of ag sound.maybe i can modify my silencer to try your idea.tiy

Kaya palay may pinagkaka-abalahan pala si bro Rex! Thanks for sharing bro nice one!

[rex]

@ batmon & snyper
thanks mga bros

hunterx

with the one obove, theres nothing special in it .Just enough expansion room for the air and the most important thing is the exit hole of your suppressor or end cap,the smaller the hole the better.Just enough for the pellet to pass thru.if you have an already made suppressor then just cover the exit hole with epoxy,when almost dry fire a pellet though it and thats the smallest hole enough for the pellet to pass thru.
If you have a long enough suppressor like 12 inches long you can divide it into two chambers with the hole of the divider same as your end cap,small as can be.The problem here is the perfect alignment of your barrel hole,the dividers hole and the endcaps hole.If you are able to get a pellet pass thru these holes without chipping, you will hear just the slammimg of the hammer/spring.

I was able to do that in one of my pcp.

[hunterx]

ah yun pala,what epoxy brand do you recommend bro?ok ba yun sa mga hardwares na epoxy?kailangan pala just small clearance ng pellet sa holes ng suppressor. i have 6" suppressor with 5 dividers,1" distance each divider but medyu maingay pa e,hehehe.i couldnt hear hammer slam nga e.hehheh

[heightaddict]

its illegal there, right? anything that suppress sound and can be used to a firearm needs a license. BATF

baka makita ng neighbors mo

[rex]

Tama ka bro height,thats why airgunners here call it LDC.Another option here is raised breech and complete barrel shroud.Mahal nga lang.The breech and shroud would cost like another gun.
Here are some pics of them

bro rex

wat modification do you recommend on my 3/4 6" long tube suppressor?? I tried to make the cap hole smaller as you have advised. ok naman pero medyo maingay pa rin. TIA

[quickshot]

bro my suggestion is palitan mo ng 1,1/4 dia.tube alum. gawin mo semi reflext ang six inches, at 6 inches din ang acoustic divider na 2 baffles, tulad sa wiechrauch HW100, twelve inches lahat ka taas, try mo lang

[cobra]

Bro. quickshot,

May pics ka diyan at dimensions. paki-share naman

[cobra]

Bro quckshot,

Hindi matatawag na LDC dahil nilagyan mo ng baffles, tawag na doon sound muffler or silencer dahil ang main concern mo ay sound reduction na kaya nilagyan mo ng baffles at may divider pa na makikita sa real FA silencer.

[rex]

@ cobra,

Totoo yan bro pero yan talaga ang purpose nyan,sound reduction.Airgunners in the US used this LDC alibi to get around with the law.

But if you really want a lead dust collector,you need a small diameter tube drill holes around it,bushings on both endsof the tube,wrap the tube with scotchbrite,insert the whole thing in a bigger diameter tube the bushings should hold it aligned in place.I'll try grab pics from other forum.

[rex]

Should look like this minus the 2 bushingsings the middle and the whole lenght covered with scothbrite.

[quickshot]

mga bros, effective ang reflex system kasi ito rin ang ginagamit namin ngayon pag maghunting kami, ako ang gumagawa sa aking silincer at sa aking kasama,yong picture at dimension later na lang

[quickshot]

bro i try mo hanapin sa you tube, type A.R.I.ES suppressor system (advance rifle integral external suppressor )system,

[hunterx]

bro Quick

ano po ba yung reflex system??pls post pics po.ty

[rex]

I made a new one,now with two chambers in it.The sound,Its like firing your AG without air.I enjoyed firing it until I ran out of air so I have to remove it to refill the AG then put it back again,then the problem of misalignment sets in. Alittle twist to either side would chip away the pellets so I have to widen the both the divider and the endcaps holes to accommodate the pellets.So back to around 60% suppression but more pleasant sound probably a different harmonics produced by the divider.

[quickshot]

bro hunterx, ang reflex ay kapareho sa shrouded silincer, cgurado ma align mo yong tip ng barrel hanggang sa butas o end cap hole na walang sabit ang pellets, ang butas ng dalawang baffles at end cap ay pareho 6.74mm or 17/64 of an inch.

[hunterx]

kulang nga lng ako sa mga tools para gumawa nyan e...maganda sana try..malayu pa ako sa machine shop..pvc pwde din gamitin bro Q??prob naman is what material gamitin to hold the tube sa barrel to align it. i have 15" 1 3/4 long pvc tube...can you give idea what to do or what material to put para ma align ko sa barrel. i think kailangan talalga ipagawa sa shop yan,

[cobra]

Ang reflex ay gingamit sa sound system Pag Alam mo yung Bass reflex sound system ganoon yun. Kabaliktaran naman sa silencer yung sound ay nag cancell out kaya mahina ang sound. Sa Bass sound system naman yung sound ay nag add para lumakas ang bass sound

[hunterx]

no idea about that bass system bro...but i made new one today,i'm satisfied with sound reduction,i think its 80% quiet now,,but sobrang haba naman kasi i used 1" dia, 17" long tube.heheheh.. may buffles din located at center portion.i can hear hammer slam. now i'm thinking to create another prototype but shorter one. question guys,,does silencer affects the power of ag???

[cobra]

Try to use 1.5" dia. by 8" or 1.25" by 11" halos pareho ang volume ng 1" by 17".

Subukan mo i-chrony yung merong silencer at walang silencer.

Seek and you shall find.

[hunterx]

i cut it short bro..12" na sya ngayun with same sound reduction..with regards to power,i have not tested it yet...i'll try the soft chrono baka ok din yun..

with your experience guys,did you noticed that parang weak yung power ng ag nyu when you put silencer?i have experience ones,i put scotch brite in my buffles,it couldn't reach my target which is 50m,it drops.na sobrahan nilagay ko..and yung design ng silencer kasi 3" lng yung space from the muzzle to the first divider.

now with my 12" tube,6" yung space from the muzzle to first divider,whisper quiet sya but parang weak yung power,....mahirap mg conclude kasi i have no chrono..but in that two designs i have parang pareho sila..so what test do you recommend to test both silencers??

or baka naninibagu lng ako kasi noon maingay ag ko tapos biglang ng whisper quiet na....hahahahahahah.ty bro's for your inputs here,it helped me alot..

[cobra]

Bro.

Yung thread ni satclic dito rin sa DIY, may computer chrony software puwede mo e download at gamitin para sa experiment.

[hunterx]

yes bro i've tried it yesterday...im not convince with the results kasi yung soft chrono it uses sound to detect muzzle sound and impact to determine the velocity and muzzle energy...

so when i tested it both with and without silencer..it has big deviation on its results on with and without silencer kasi nga sound need nya to determine the muzzle vel. and energy..

and isa pa,you need to fine tune it..ok sya if you only want to determine the fps of your ag..

[cobra]

OO nga pala kailangaan ang sound para marecord ang time lapse. Sorry bro. nakalimutan ko sound activated pala yung software chrony ang kailangan yung light activated chrony.

[rex]

Yan din akala ko noon,akala ko there is loss of power.With my quite as mouse fart extension shroud for talon,akala ko sira ang valve o walang laman ang tanke pero nung itinira ko sa swinger at 20 yards malakas naman ang impact/swing.

[hunterx]

ok lng bro cobra...

bro rex yan din ginawa ko.listen nlng ako sa impact,parang ok naman.heheheh.
