I use an ANS quick fire and it was a 3 mm pull, I did some grinding of the rod where it enters the trigger plate, looks like a D instead of an O, it increased my pull to 3.7 mm and opened up the timing window a bit, and is much more forgiving when I short stroke it's helped me out a lot. Razor : and Razor is right about what I meant about the trigger pull. The actual trigger movement, lowest part of the trigger is 5MM, trigger rod movement is 1.5MM - 1.65MM. The trigger pull on my ANS Quickfire was 3MM, longer trigger rod movement shorter trigger pull. However, it's almost impossible to short stroke with hinge setup. The only things I have upgraded on the STO are the x-way,barrel, and the trigger frame. Efficiency is approximately 400 shots per 1000psi on a 68-4500 tank at 286fps. : Rick : : Yeah, I got an tornado valve and I got it to operate at 200 psi ONCE. It was like the perfect paint barrel fit day. :) : : The trigger plate slot would give a longer valve dwell time I imagine. But if it's a hole, then that's pretty good timine imho. : : : I think low pressure is anything under 500, but cockers and their clones can go considerably less, AKALMP claims 180ish psi operating pressure for their Merlins with Tornado valve. I think (if I read correctly) his trigger rod movement is 1.5 mm, not the stroke of the trigger, I believe the trgger pull of swing triggers is actually longer than slide triggers. Hope it helps. : : : Razor : : : : : : : Is yours HP or LP. The way I understand it is that LP markers (~200-250 psi) have a longer "valve dwell time" which in turn requires a longer "bolt forward" duration during the trigger stroke. Thus if you make the trigger too short, you will get blowback with an LP marker. Should I increase the operating pressure to make a short vavle dwell time ot get this 1.5 mm tigger pull? 1.5 mm is pretty darn short. You aren't exageration are you? ;) : : : : Also, do you use a stainless steel bolt to make your cocking "slower" from the inertia to prevent blowback...if this extra weight actually makes a difference! : : : : : : : : : I've got a 2k1 STO with the "Bomb" and a WGP hinge. My trigger pull, movement of actuating/timing rod, is slightly more than 1.5MM. This is with suction and functioning mechanically as it should. Any shorter and you will you start to sacrfice overall performance of your marker. Suction is the ideal but as long as you don't have any blowback you're OK. : : : : : Rick : : : : : : : : : : : How short can you guys get the Bomb 3-way stroke and still work properly. Can you still make it "suck a tissue" into the feed tube when making it real short? It seems the shorter I get it the less it makes a vaccuum on the feed tube. : Is this vaccuum really neccesary like some people say? I mean sucking a tissue won't have the same effect on a heavier paintball right? As long as you don't blow the tissue out, my guess is that its the same...correct me if I'm wrong. : : : : : : Thanks for any! :)
