Thanks for the info. I read through both, and dug out my old 2.5 that came out of my Revo, as well as the old sleeves from it as well. Did practice on them(already pretty steady with a dremel to begin with), and after practicing on 3 old sleeves, went at my os18tm's sleeve. Didn't go radical because I can always go back later and do more on it if I feel it is needed, and you can always remove more metal, but can never put it back. I'll see how it works out once I get some other parts in and let you all know. Thanks again for the info.
