Superpolishing L10 piston

[legion]

Heyas everyone,

Im not sure which forum this should go in, tech, deep blue, or here, but I figured, this gets the most traffic so I'll ask here.

I was wondering if it would be possible to superpolish (1200-1800 grit sand paper) the piston on the L10 Superbolt II, so that it has less friction, which in theory, would cause it to have less bolt stick problems, and possibly run on a slightly smaller carrier...

Let me know!

I would like to know this too.

If you polished it.. wouldnt that eliminate the point of level 10?

lol personman what u mean by that????

yes u could polish it.. it would work better with the smoothness but i think it wouldnt be as sencitive.. u would have to play around with it more.. (i wouldnt but it wont hert)

Yes this is possible but 1200 grit is too rough. Use brass polish or something similar. It must look like a mirror to make a difference. SEE more fun stuff to Super Tune!

I thought level 10 was mainly adding friction to the bolt.. If you take away the friction, then wouldnt that eliminate the need?

Friction

The main engineering feat of level 10 is not friction, but the stepped piston surface area while remaining retroactive.

By reducing the friction of the piston, you are now able to add a harder spring. The friction is no longer holding back as much, so you can add the harder spring to compensate.

Controlling the amount of force of the bolt is much easier by the spring. Using the piston's friction requires a constant lube on it.

Because the lube changes with play, it is much more desired to polish it and rely on spring force, not friction.

Springs are more predictable and consistent than friction of the piston.

That's why I want a longer spring!!! Please! Longer spring?....please...

Yay! looks like i have a new project to undertake! I'm going to stop by a hardware store probably tonight and pick up some brass polish, and turn this baby into a mirror, I'll let you guys know how it works out!

Legion, is the piston you're talking about, the pin that sticks out of the back of the new bolt? The part the carriers go on? I dont have my LX yet, but your idea interests me.

Yep, that's the one I'm talking about, too bad i didnt get one of the dud superbolt II's that was separating ;-) would make this alot easier to polish, but it should still be possible...

Hey tom/anyone that would know... How difficult would it be to remove the piston section? Or is that brazed / perma-loctited in?

the piston is NOT removable. Remember, you have to polish the part of the small piston all the way inside the bolt to make a difference. The end sticking out does nothing to help with bolt stick.

I'll see what I can do, I should be able to get all the way in there with some sort of modified tooly type thing

Hrm, regarding brass polish, what brand / type would you reccomend, I went to home depot and asked about brass polish and they pointed me at some cleaner, not actual polish... Any information would be helpful, thx!

I've got some extremely fine brass polish that I used to polish the brass barrel on my Palmer Blazer. Probably too fine, but you're welcome to try some. Just meet me at Sam's sometime and remind me before hand and I'll bring it. In the meantime, how about some type of chrome polish, like mag wheel cleaner? For brass, you shouldn't have too hard a time finding something like Brasso, but I'm not sure how abrasive it is.
