it to split?  Past the nice

taps and intermediate bangs.

Looks great inside so far.  Haven't miked anything yet, everything looks

like new.  Feel guilty

now for tearing it down.

Barny,

Is that shaft splitter you are using the one I made?  If so, I'm surprised
that you can thread it far enough into the hole to get much of a whack on
it.  The splitter threads are a bit oversized.

It took me about half a dozen increasingly harder whacks with the slide
hammer until it popped.  Once it does pop, it goes all the way... no
"loosening".  It just jumps right off of the taper.

I know what you mean about these engines... extremely little wear anywhere.
Just lots and LOTS of carbon.

There's a new Harbor Freight in town.  Lots of very low cost (and relatively
cheap quality) Chinese tools.  Just the ticket for parts washers, bending
brakes, etc. for hobby use.  Checked 'em out yesterday.  Gonna spend some
Christmas money there.
