[Steam-engine] Oil Grooves/ Huber progress.

[Andy glines]

Good answer!  Thanks to everyone who wrote with an
answer.  I have the grooves cut in the caps and the
crank is fit.  There will be no grooves in the bottom.
 I'll be assembling the rod, crosshead, and piston
next.  Then I'll find out if I got the crank in the
right place!  Pouring the crank bearings was the last
big task that had to be done.  Now I have a lot of
assembly ahead of me.  I'm really looking forward to
pulling the throttle (which I also reassembled with
new parts this weekend) the first time.
