This week end I am going to chuck the piston in the lathe and make sure it is truely round.....  

I am willing to give this example a try and trim .002 off the top portion of the crown...

I think I will bead blast the skirt too...

Being a guniea pig can have benifits..........or not.....

I am going to have the local machine shop properly hone it so I though I would request another .0005 off the bore to be safe.  I could hone it by hand with a drill but I want the proper hone mark angles.
