can someone tell me how to turn a stock f/a Rainmaker into a pump or fully pneumatic marker? I think I have the pneumatic version figured out but I'd like to hear from an "expert" before I attempt anything.

Sorry if this question has been asked a lot. I would have done a search but many times searches come up with too much useless stuff.

Thanks

Well, I'm no "expert," but I do own a pump and know how it works. Firstly, the pneumatic ram is removed, and the carrier is attached directly to the pump arm of a pump kit. Since no pump kits are actually made, this will need to be fabricated. You will also need to rig up a sear system to trip the hammer when you pull the trigger. When you pump back, the carrier will grab the hammer. Pumping forward will line the hammer release up with the sear, and pulling the trigger will launch the hammer into the valve, and you know the rest. Due to the Nelson design, an autotrigger is a side-effect of the pump kit.

well if I'm right about the fully pneumatic operation, I think I'm going to stay away from the pump. Anyone wanna shed some light on the pneumatic operation?

Basically you yank the Electronic 4 way valve, Battery, board, Etc, And replace it with a Mechanical linkage to an Autococker 4 way, Clippard 4 way, or a Maximatic air piloted spring return 4 way, slaved to a SMAV from clippard.

Instead of an electronic piloted 4 way valve, you have either a mechanical or pneumatically piloted one.

look at a palmer's Stroker frame...

replicate that inside your RM frame

done and done.

(hint hint... check the Custom Markers area for my thread on this subject... i have peektures there...)

But the Stroker has a dual-stage trigger.
Rainmaker conversions work like Vectors, with fully pneumatic triggers.

At one point, I had mine converted to pneumatic, then pump.

A fully pneumatic conversion can be done extremely cheaply, using only a left-over cocker 3-way valve, rigged to the trigger. Thats not ideal though. Most conversions use a Clippard valve, with some sort of linkage.
Still extremely cheap for an insanely fast mech gun.

Rainman did my pump conversion. As I remember, he:
1- Made a custom front plug, to adapt the pump to the bolt carrier.
2- Made a custom trigger/grip
3- Remove the sear pin.

It's been said before, I'm just repeating - Vectors DO NOT have a pneumatic trigger, anymore than a Cocker has one. It still drops a sear, it just activates a 3-way as well.

if money is no object, just order a stroker frame without the sear parts (PPS will sell it like that if you ask), get a frame adapter, and just configure the stroker frame so that the only thing the trigger does is move the switch. Easy to configure, very adjustable, and very short trigger.
Just don't remove the QEVs from your ram since the hoses going to a switch in the grip frame are going to be fairly long...

Holy crap Hurt Cow! That is the most beautifully ugly awesomely fang-dangled thing I have ever seen!
