X-mag reanno tolerances

[Chaos_Theory!]

SFL Xmag body, what? lol

Anyway, no you wouldnt lose detail on the gun.

Im pretty sure either way (dusted or polished) it wouldnt make much of a difference.

but you can re-anno x-valves right?

yes you can. HOWEVER! if you do, you void any and all warranties on your valve.

Ok..lets talk the basics of anodizing. A standard anodize is .001". Lets make that .0009 for argument stake. 2/3 of that layer is on the surface, so 1/3 is sub surface. Most companies when having thier parts anodized a Type II anodize dont worry about using the anodize to bring the part into tolerance. So when you go to re-anodize a part and strip it, you are removing 2/3 from the surface, and 1/3 from the actuall part itself. So in reality when you remove the anodize you are only removing .0003" of coating from the part. so when you rebuild the part with the new anodize your part has only shrunk by .0003". If you do have tight tolerances, it can effect it, but only after several times of stripping and re-anodizing. I actually recommend that you only do it 2-3 times for the high end marker that does have tolerances that need to be kept in check. You can do it more than that, but you are taking a risk. This risk is compounded by not using the proper aluminum stripper to remove the anodize layer. The home brew methods of oven cleaners, and lye dont have the grain enhancers and additives that keep the etch from removing aluminum also. Even with my commercial grade etch, you can still damage parts if your not paying attention. So if you have the stock anodize right from the factory, you can anodize it again. So yes it is both myth and fact.

so yes, you CAN re-anno your valve. how ever do it more then 1 or 2 times you WILL have problems. i HAVE seen re-anno'd valves work flawlessly after 1 reanno with origional o-rings

Do you HAVE to strip the old anno first of is this a over coat process? If it is stripped first, then the re-anno of the barrel, pluged or on, shouldn't even make a difference, right?

yes it needs to be stripped. and that is where you truly lose the aluminium during annodizing. because anno is 1/3 in the aluminium and 2/3 of the color is on top of the aluminium. so if the thickness of the anno on top of the aluminium is .006 then there is .003 of the anno color physically in the aluminium which needs to be stripped off just to reanno.

understand?
