Milling "windows" in the spring travel area of body

[warfinge]

If I decided to mill openings into the sides of a slug body that were in the bolt spring travel area, could any of you foresee any problems I might run into? Not a huge amount of meat just enough to expose the spring. I only get one shot and I want to make sure before I cut

Cutting Through the body in the area of the bolt return spring. I don't think there would be bad effect other than dirt/paint can get in there. It shouldn't effect operation. Am I wrong?

Sounds like a interesting concept. I think it would work. Anyone else have any ideas about it?

[redlaser666]

I dont see why it wouldnt work, all you would be doing is exposing the side of the bolt and the spring. You have to consider that getting anyting lodge in that are once it is exposed will jam the marker. I can sugest carefully cutting and gluing some plexiglass or lexan windows.

It would make a cool efect to see it in action.

I thought about plexi but after oiling the marker a few times, that wiould be nasty maybe. I could mill a shouldered slot for it and try it I guess. If it didn't work out, I could just take the lexan out.

might want to try on a ule or ss body first. they will be alot cheaper.

I just thought, we have seen round springs being compressed and bad things happen when they're not guided, but we've never seen this with the automag spring, we don't know if it'll do the same exact thing.

Im thinking that the bolt would act as a guide for the spring since it is in such close fit with the spring. When designing we use this type of guiding quite often.

[Bad_Dog]

in my opinion the bolt will most certainly act as a guide.

ever compress a bolt spring with your fingers outside the mag? does it go everywhere? no. it compresses in a very liniar motion... if i can find the micromiter i have laying around here i can do a simple test in a matter of a few minutes to see if it's circumference increases, that will be your answer.

[Bad_Dog]

from measuring the spring from my pump mag, it expanded exactly .01 in diameter when compressed compared to normal.

.005 increased radius, I do not think this will cause any problems with your window idea.

this may provide a nice path of least resistance for blowback and possibly hurt the efficiency.
It's about the only thing I can think of besides dirt that would provide trouble.

My thoughts exactly..

My thoughts exactly..

could you fill me in on this? do you mean the path of least resistance for the air to flow out of the marker? as in less air behind the ball?

The air will want to flow out of the marker where it finds the least resistance, meaning it will take a short cut between the start and end of the barrel if possible. Just like a ported barrel looses the pressure behind the ball when the ball reaches the first ports.

It may work, but it will take more air to run it. (Same as a long ported barrel)

I think he is talking about part of the charge of a shot traveling around the bolt and escaping through the windows. While upping velocity adjustment to compensate for this "leak" is very easy, it could impact your shot count if you are wasting air. I personally don't think it would matter much but I'd have to experiment to be sure.
