G7 self cleaning Eye bolt mod?

[dilligaf]

Is there anyone doing the self cleaning bolt mod for the G7/G7fly yet? My soft face ripped off and I need to purchase a new bolt. I was hoping that someone has drilled the bolt, so it works as the new Self cleaning Angel 1 bolt. Please help.:smiley:

I know Ken Crane of Performance Angel & Robert Moon of Fix My Angel have been performing this 'mod' on Angel bolts for quite a long time, even before the Angel One.

Contact them and ask if they can predrill the slots in the bolt for you prior to shipping it over.

The MTs were going to sell this as a MT bolt with the eyes and another feature on the bolt that is seen on the A1 but they never said anything else as to if it was going to happen or not.

ok, so what does this do exactly? Do the holes allow a little air to clean out the eyes when the gun cycles everytime?

I purchased an Arsenal Fly recently (thanks again, Plum!), and it had this done to the bolt. I wasn't sure at first because I hadn't seen it prior to this, but after a few minutes looking at it, I figured it out.

It works like a champ too. We actually took a ball and broke it over the breech and let all of the fill drip onto both eyes. With no paintballs loaded, it only fired two shots with the paint fooling the eyes into thinking there was a ball, but after those two, it sensed that there was no ball. One of the best things I've seen for proper eye function.

Out of boredom, I convinced another local guy to let me try it on his 6 Speed bolt. I just (bravely) took out the eyes, pushed the bolt to the forward position and went very slowly with a hand drill through the eye sockets. Gladly I can say that the patient came out of surgery in perfect health, and it works just as well as the bolt in mine.

Highly recommended, provided that you're fairly competent with a drill.

Would the holes be drilled straight into the bolt? Or could they be angled to with the opening on the outside right over the eye so the "escaping" air would push the paint down the barrel? The holes would be drilled so that rathif viewed from the top, if a line were to through the holes they would intersect further back in the bolt. Take a look at the drawing I have attached and let me know what you think. Please excuse my poor drawing abilities. Thanks.

Your drawing wouldn't work, because the holes would be well past the eyes when the valve was depressed, so they would never actually blow on the eyes themselves.

Mine just has the holes drilled perpendicular to the bolt travel, with the holes visible through the eye sockets when the bolt is pushed all the way forward depressing the valve completely.

[lipe33]

If the holes were moved furter back on the bolt, so they were right over the eye sockets when the bolt is completely forward do you think it would work? I'm trying to figure out a way to get as much of the paint to go down the barrel, instead of further up the bolt. I'm sure what you did works great, I'm just thinking out loud with this one. What do you think? Thanks

Well, the angle doesn't really matter enough for it to be worth the extra effort required to drill them that way. To drill them like that, you'd have to mark the position just right, then take the bolt out of the marker and probably chuck in it a vise at juts the right angle and then drill it at the right angle, all without guides. On the one I did, allthat was required was taking out the eyes, pushing the bolt all the way forward and going slowly with a hand drill that was just a little smaller than the eyes themselves. The eye socket did all the guiding for me.

The angle has little effect I think, because the air form these holes is going to blow the paint in the direction of the least resistance. So if the pressures dictate that the paint is going rearward with your set-up, you could have the holes facing as forward as you want and the paint is still going to go in the direction of the lowest pressure.

You could direct that flow forward if you wanted to, by cutting small channels about half the depth of the bolt's thickness, from the holes to the nose of the bolt. That would ensure that the path of least resistance is forward, and it would probably promote a little venturi effect which would help draw the paint forward as well.

[lipe33]

That makes sense. I hadn't even thought of that. You said that the holes your drilled were a little bit smaller than the diameter of the eyes. How much smaller? I appreciate the helpfulness. Thank you and God bless

I used a 5/64" bit to start a pilot hole with the bolt pushed forward. A slightly larger one like a 3/32" can be used to enlarge the hole just a bit after drilling the pilot hole.

I think you should find a way to use extra rubber from the soft touch part in the front of the bolt, and have the ends of it coming out the sides of the bolt in front of the holes you drilled, to act as a type of squegee (SP) for the eyes. Therefore when the bolt moves forward, the rubber will wipe out any debrie from the eyes, and then the holes will blow clean the eyes again, and as the bolt is returning back again, the rubber will again wipe clean anything blown out of the eyes.

[S1NN3R]

But the eyes aren't flush with the breech, so a wipe wouldn't clear anything that's below the level of the metal, and anything above the level of the metal would likely already have been cleared by the bolt itself. Unnecessary complication with no performance return.

has anyone modded there bolt and has it work? and has anyone asked any mts if u could ordered one from them already done or send in a aftermakert bolt and have them mod it?

[Technix2002]

I like the air channeling idea also. If you could channel it along the path of the detents it would also blow air past them too (though it could also blow paint on them....). Just a thought.
