Re: Subject: Valve shim question

[Skipatnode@domain.elided]

    Can valve shims be milled down and used, or do they have to be purchased 
at the correct size? I think they could easily be lapped down on a piece of 
plate glass, some 400 grit wet or dry paper, and some WD-40. I am wondering 
if this process would take off some sort of coating or if the top of them are 

hardened or something. What is the thoughts of the digest?
      thanks,

       I did this in an emergence many moons ago with no adverse effects.  
But I don't suggest it as a regular practice.  They are harder than Chinese 
arithemetic and it takes forever just to lap a couple of thousanths off.  I 
have since acquired a set of spare shims and have found that to be a whole 
lot easier and quicker!
