Titanium parts in a cocker

[Acidd_UK]

Quite a technical question but here goes -

I have just spent a considerable amount of the taxpayers money on getting a very nice racegun cocker setup. Since the cocking speed (bolt open and close times) are directly related to the weight of the cocking parts (bolt, back block, block pin, cocking rod, hammer rod, hammer and spring tension) then making these parts as light as possible seems the obvious way to up the max bps. Since I have a delrin bolt and pin, and an evo back block, the only things left to lighten are the hammer and spring.

What would be the effects of using a titanium hammer? I assume I would need to use a much softer valve spring to compensate - has anyone tried this or am going to be breaking new ground? Also - any tips on how I can use the softest main spring (again to speed recocking?) I am using a low pressure max flow so the input pressure is limited to a max of 300 psi.

Any comments, theories or experience would be greatfully digested.

Off the subject slightly but have you a eye fitted to your cocker ?,as this would speed up the timeing allowing the gun to shoot faster.

titanium

yeah u could use a titanium hammer and cocking rod to improve the speed you would probebly need to use a softer valve spring to compensate. however you should install a low pressure valve as well to help with air flow, extreme rage have all the Ti bits u could ever want :
TI Rocker Knob
TI Cocker Valve
TI Cocker Hammer
TI Velocity Adj
TI Cocking Rod

Suprisingly, you want a heavier hammer. No, trust me, you do

I've got the RaceGun 45g bronze hammer in my cocker, it allows you to use a nice light main spring, so the ram is working against less spring tension. If you lighten the hammer, you need a harder spring to open the valve enough to get any decent velocity - either that or you end up with a valve spring so soft your valve doesn't close quick enough, causing lovely wonderful blowback!


What you really want to max-out your bps, is a sexy fast ram (a new freeflow SMC, or one of the new Belsales (I've heard good things about these), a delrin bolt (although if you've not got the ACE fitted, I'd consider a JAM bolt (they just dont chop - see Sparklie for more details in the UK ), and defo get a Halo B (can drop your load time to 10ms).

I don't know what cocker the race is sitting on, so you may already have some of these components.

Oh, and a couple of things Tom - you spent the taxpayers money? you mean you get grants? not just loans? (in which case, it's your money really, it's just a loan). Flippin students, prepetuating the image of us all as scroungers

2nd thing, this time when you fall over, you'll shoot yourself two or three times in the leg, not just once
