[SEL] Piston Ring Gap

[Luke Tonneberger]

Hi Jack,

It is air cooled with an aluminum piston. It is for a model I'm attempting 
to make. I have the bore close to finish size. The piston fits, but the 
rings don't fit yet.  I put in a piston ring and can't quite get the ends to 
meet. The bore is too small yet so the ends of the ring overlap a bit. I 
need to hone it out about .015 inches I'm guessing. I'm using the end gap on 
the rings to determine what my finished bore size will need to be and how 
much I'll need to hone it. I've read a little on how to hone, but not sure 
what to use for cutting fluid.
