Gwapo nang idea nimo para sa fabrication of springs sir. Medyo mahal man gud ang stock TM springs eh. Dapat sure-ball lang gyud nato ang kagahi sa atong buhaton para dili pud pwersado kaayo ang motor ug gears sa AUG nato.
Murag tantsa nako na between STOCK TM and M90 ang perfect strenght eh. Some guys recommend worn-out M90s or PDI120s if you can ask them from our HI-END playing comrades in arms
Gahi-gahi na pud ang STOCK CLASSIC ARMY spring na luma. Pero the latest batch of CA stock springs are almost M100 ka-gahi! Pwerteng gahia! Dili halos makaya sa 9.6v batts!

mr733 springs lng basehan nato sir stan kay na testingan na man nko and it works.... so far. cguro i'll have 10 springs fabricated muna kay mgpataod na man pud mga STAG players. regarding sa high-end springs, murag mag lisod ta ana and yes, it would cost more and difficult to find.  |

here it is! my ported piston ;D oo nga pala, im not saying "this is how to port your piston head" rather im saying na "this is how 'I' ported my piston head". wla kac nag turo sa akin and i thought of this all by myself lng, ofcourse the idea came from some players in ACMGames kaya dont expect much from this modification..... but it did made my steyr fire .2g bbs (using MR733 spring) at the same range or even longer than stock BE steyr using .12g bbs.  ok, here it is!  this is the stock piston head  piston head without the rubber  i've cut the rubber to be aligned later to the holes...  i used the rubber to mark my holes para sa pag drill ko...   ayan, nabutasan ko na, medyo hiwi lng hahaha  pasensya na rin sa fingers ko, rubber yan pumasok sa nails ko after ko pag cut...  and finally.... the ported piston head! ;D  as much as possible, preserve the rubber, this greatly affects the durability of your piston head.hope this can give u guys some ideas... also, pde pud cguro ang piston head sa mga high-ends, i think kasya sa BE cylinder.... kato kay bakal gyud and i think very efficient in compressing air... pero ang presyo... ambot lang, murag mahal |

post pud diay nko how to reinforce your hi-cap mech... dugay na unta nko ni gi post, wa lng ko panahon.  this is my mech, as u can see, nabali na ang other side sa clip... gamay na lng kulang, bali pud ni ang pikas.  find a metal ring, kani ako from a keychain or keyholder man cguro.make sure it will fit.i think pde pud ang wire na gamiton pag reinforce sa clip.   this is how it looks like after gibutang ang metal ring.use a long nose plier to firmly grip the ring to the clip.  here, i tested to compress the spring coil... as u can see, dli maapektohan ang spring sa metal ring. so, that's it boys.... kani dli na ka mabalaka og rewind sa imo mech! ako, i rewinded the mech for 40 "kamots" (safest full rewind i can recommend) and still, ndi na bali ang clip. FYI: it takes 2 full rewind to unload all (330-350 bbs) from ur modified hi cap mag (just my observation). |

Thanks Sir Gemboymagz, This is going to be my next project.
Tanong ko lang din sir anong size ng drill bit ang ginamit mo na pang butas?

Thanks Sir Gemboymagz, This is going to be my next project. Tanong ko lang din sir anong size ng drill bit ang ginamit mo na pang butas? parang maliit yun sir, dont know the size exactly pero may guide yan duon sa piston head mismo.... meron sa akin e. just look closely dun sa piston head after mo matanggal ang rubber.... may apat na circles duon. yun sana yung target ko e kaso medyo na "off target"  ;D |

Ay salamat kaayo sir Gemboymagz sa mga pics nimo! Proven na gyud na dili mga dalok ang mga taga Mindanao sa mga "secreto"! Nice job on the piston porting sir. Looks like a sound design in principle. I don't doubt na naka-improve gyud sya ug performance sa imohang AUG. Congrats sir!
Regarding the TM piston head- dili sya sakto sa BE Cylinder. Dako 'ra kaayo ang sa TM. You either have to use a TM cylinder(and cylinder head) with your TM Piston head... OR... Trim down the TM piston head to BE cylinder size.  Wa pa nako ni gibuhat kay nasayangan ko sa TM piston head. Besides... with the porting job on the stock BE piston head- murag satisfied na ko ana eh. Will dig out my drills and get working tomorrow! Mahay gani ko kay ngano wa nako gi-uli ang akong drils dire sa balay!!!!
Sa mga gusto pud sundugon ang MOD ni sir GEMBOYMAGZ-ayaw kahadlok guys! Naa koy duka ka sets ug spare BE piston heads sa tindahan...  Just in case you f**k up your drilling. Hehehe.
Da-best pud imong hicap reinforcement sir GEMBOY! Simple but effective gyud! I'm sure daghan makinabang ani. Mangita pa ko ug keychain dire sa balay na pwede i-murder! Hehehe!
[/color][/quote] a ganun ba sir stan? may nakita kac ako na piston head... maybe ndi yun sa TM.... bka CA yun.nyways, i'l try to bring a sample of the BE piston head para masukat dun sa nakita ko.... |

WARNING!!! bago lng nko na obserbahan.... if you port your piston head... mo kusog gamay ang compression sa air (as expected) pero will send your .12g bbs up due to the hop up and increased pressure. since dli basta basta ma adjust ang hop up (dont know ngano adjustable hop up ang sulti sa steyr..) dont port your piston head unless u would decide to change the spring and use .2g bbs.unless of course u cn do something about the hop up, u can continue using ur .12g bbs with increased power! |

Tnx for the warning sir. Expected man gyud na sya. Ana pud ang resulta sa mga spring upgrades ug o-ring upgrades namo. Mas ganahan man pud mi sa .20bbs kay mas stable ang flight ug dili dali ma-tarog sa hangin.
Kung gusto gyud nimo gamiton with .12bbs ang imong AUG. Just file-down the hop-up dimple until your .12bbs will fly straight again. Trial and error lang sir. Tanggal gamay - then testing... liha nasad- then testing...

sir, noob question lang po. what's the concept behind posting the piston? how does this improve power? gusto ko lang maintindihan po.

Post by SANDMAN on Aug 26, 2005 10:08:46 GMT 8
chanbri- the answer is in page ONE of this thread sir. If you had read it first, then you would have found this:
An additional benefit of the ported piston would be an improvement in battery life compared to using a thicker(and heavier) o-ring. If you have a ported piston, you can even use a "loose" o-ring- even one that doesn't seal the cylinder properly- kasi it will simply EXPAND during the compression cycle. If the o-ring is LOOSE- di sya mabigat sa gears at sa motor- therefore- mas tatagal ang batteries mo.

all is true regarding ported piston head... setup: ported piston head stock o-ring size but replaced w/ better quality o-ring TM M4 barrel well-lubed cylinder weekly barrel cleanup homemade suppresor kit (working suppressor extends stock barrel length by 2 inches) result = 220 fps using .2g bb's on chrono (produced mosquito-bite-like marks on acmers bare skin engaged at around 20-25ft), battery lasts better than stock thanks ACMDavao for the infos... |

up your drilling. Hehehe.
