Adjusting the Ram

[JamWagon]

I have heard several procedures for adjusting the Ram to elminate chopping. What is the best way to do this? Does the marker need to be gassed up? I also heard that the ram should only be screwed inward and then reversed when it is screwed all the way in. Thanks for the help.

You could do a search for this and come up with a lot of posts, but here it goes...
Yes you should gas up the marker when setting the ram, if you move it too far forward, you must degass the marker, back out the ram some, regass and start again. You want the bolt pin to make a clicking sound on the back of the ram, not the front, meaning you will have to put it in a little farther if you hear a click early on. You do not have to move the ram all the way forward before backing it out. The best way to do any ram adjusting is with an angel tool.

Adjusting the ram supposedly removes rollback which eliminates chopping.

"you cannot eliminate rollback with a STOCK speed05"

To eliminate rollback, you would have to push the bolt forward so that is is flush with the rear of the feedneck(i.d.). If you were to adjust your hammer/ram to that point, you would not be able to open/close the roto-breach.

How did WDP solve this problem? The G7's lever-lock. Once the lever-lock is in the closed position, it pushes the bolt flush to the rear of the feedneck.

You can duplicate the state of having the bolt flush with the rear of the feedneck by drilling a hole on your back plate on the ram side. The hole should be the same diameter as the angel tool. Once you "air-up" your marker you should then take the angel tool and screw the ram "clockwise" so that the bolt is flush with rear of the feedneck. Once you remove the air from your marker just turn the ram "counter-clockwise" and push the bolt with a stick so that you can open the roto-breach.

Someone should design a hammer/ram assembly so the a user can adjust the bolt forward easily.

Having the rotobreach is nice but By design, all WDP markers prior to the G7 should all suffer from rollback.

JamWagon...I hope this info help you with your problem. Again adjusting just adjusting the ram will not eliminate rollback. You should drill the back plate then adjust the ram once the marker is "aired-up" and make the bolt flush to the rear of the feedneck.

get a jam bolt. That eliminates roll back too...

just adjusting the ram to the point that it causes the bolt pin to click into it will fix your chopping problem, the rollback issue may be a problem if you're anal retentive but you wont chop as long as you have a good paint pusher on top of the ol' marker. that's my 2 cents.

My rollback problems were cured by stopping using the Reloader B and going to a different hopper. The rollback issue causes the second ball to be pinched or cut.

Take closer look. If you move the bolt/hammer closer to the valve, wouldn't the hammer smack right into the valve and really screw things up?

There is a point when you cannot turn the ram in anymore. On the speed05 I tried, the bolt was ALMOST flush to the rear of the feedneck. The rubber part of the "soft faced bolt" will then minimize the rollback encountered.

Why do I do this?

ROLLBACK CAUSES 2 MAJOR PROBLEMS?

1. When the ball inside the breach rolls back, the ball on top of the breached ball partially enters the breach. This will sometimes cause chopping. This problem is also compounded when using smaller sized paintball (i.e. RPS MARBS).

2. When the ball inside the breach rolls back, there are some occasion the marker will not shoot due to the fact that the eye does not see the ball. The paintball is no longer tripping the eyes.

These 2 problems from rollback should warrant some concern. The last thing I want myself or my teammates to think about during a tournament are the size of paint, what hopper to use, and breach and barrel full of paint from chopping.

If there are any other suggestions on how to remove rollback from pre-G7 WDP marker, I would love to hear it.

Have you done this Modification yet and if so can you post up some pics? Not sure I would be game since I don't have any rollback issues, but others might like to see.
