To Polish or not to Polish?

[Dr.Bong 4:20]

Why do people Polish their internals? The only part that moves inside the a-5 is the valve, which is inside the power tube. Nothing else is really moving around. Also Tippmann doesn't recommend doing this because you can over polish and cause micro leaks and you really dont want that!

tha bolt moves

polish it if you have time

[A-5 user]

You are wrong my friend. The front bolt and rear hammer which opens the valve move. I think you have your info wrong because the bolt/powertube take the most minimal movements. People polish their internals because it makes everything move smoother in theory. I dont see how it would cause leaks. Maybe polishing or drilling your valve could, but polishing the parts of the reciever where the bolts move couldn't cause any major harm unless you really milled them out. But then again people who do the 98c quick strip mod (you cut one receiver half in half) don't have problems either... Alright I just realized I am rambling so I'll stop now.

EDIT: When polishing use steel wool ^_^

As stated above. Polishing the internals allows for smother operation... a lot smother. Why? The rear bolt which is put back in place by blow-back gas (hence why this gun or any gun using a counter weight in it, is called a "blow-back") requires less pressure to reset because their is less friction between the bolt and the gun (because you polished the internals, there is less friction between the bolts {both front and rear} and the internals thus meaning less gas used to move the bolts thus meaning increased efficiency). The actual internals of the gun will cycle slightly faster, be smother and efficiency will be increased because the operating pressure (the pressure the gun needs to re-cock itself) will be lower (also allowing for slightly more shots per tank.

Its a very efficient thing to do especially plus a reg. I'm doing it within the next week.

As for micro leaks... I don't see how unless you really really really went at it which I don't think anyone has done. No one is milling the guns internal metals so I don't see how. Your not screwing around with the actual power tube so I'm 98% sure causing micr-leaks is impossible (unless you ruin the gun). But I'm not sure. Someone should look into it.

For example, ever seen a spyder shoot? (duh)

The bolt on top that moves rapidly every time the the gun shoots, that same amount of fast movement goes on within the A-5, you just don't see it.

yeah, i wouldnt recommend using a dremel for polishing. use #000 non abrasive steel wool..

I think your over estimating it a LITTLE bit
your talking verry small amounts of efesantiy

I did it because i had the time to do so. Not sure if the benefits are very obvious, but it has reduced the wear and tear on my bolt which is always nice.

A dremel with polishing wheels and Mothers Mag works very well with less abrasion than steel wool. It's what I used initially to get a nice mirror finish on my internals. Now every time I clean the marker I just touch it up with a rag, a little polish and some elbow grease. My efficiancy increased noticably after polishing.

[cogs759]

Ah, Mother's mag. . . Probably the best ting to happen to my tippmann ever... Used it for both the internals, and barrel inside. (After finding a good paint/bore match and polishing that barrel, I could swear that my stock barrel is as accurate as most of the cheaper aftermarket barrels.)

[Monkeyeez]

One cool thing about tippmanns is that you really don't have to polish them. Just play w/ it for a long time even let it get a lil dirty. It will polish its self over time. Then just open it and clean it. It should have worn on any areas that you would have wanted to polish.

[robspar1]

I'll polish mine when I get around to it (that is, probably never ).

exacaly lol like i said if you have time
i cant really see a oboise benefit ither. but i know it does help now that i have a reg (along with leaving my gun cocked over night) i can easaly run the gun at 600 psi or a lil less

how do you polish ur gun anyway?...and what does it do?

Do you.....not read?

[compasteedee]

I polished my internals of my 98 custom a while back, but I now have a problem, my gun double fires. When I did it I actually polished less than I though I should because I didn't want to run the risk of wreaking my gun. I tested my marker shortly after and found it was double firing, but thought it was no big problem, because after all it was set to almost max velocity, so I turned it down and tried to tune it. However, it didn't stop double firing until the velocity screw was in as far as it could go.

Now, to be honest with you I'm not entirely sure if is directly related to the internal polish, but I checked and rechecked the assembly, and went through everything that Tippmann recommends in their troubleshooting guide, and the problem persists.

any suggestions??

Same here. Keep it clean, keep it lubed, and the parts will break in to each other naturally.
