I am a mechanic in charge of inspection and bearing recondtioning at Anderson Aeromotive where we overhaul large radial aircraft engines.The use of silver in these engines was used on alot of different componets in fairly thick amounts depending on its purpose.Some of the silver is easy to machine off and some is best removed with nitric acid.I have just started using the acid but have been waiting for the weather to warm up.This is best done outside far away from anything painted or that will rust.I took apart a 1/2hp motor today for the heck of it.It went pretty good till I got to what I think is called the stater.Gonna have to do some research on that one,right now I think it should be called the devils seed.I made quite a mess of it.I'm pretty good with radials but when it comes to electrical I'm maxed out at batterys.
