[Steam-engine] Oil Grooves/ Huber progress.

Good advice Richard.  We have done quite a bit of
scraping so all is well.  Don't worry about insulting
me.  I lots to learn.  I never considered breaking one
of the caps.  Luckily caps alway had their shims when
they were installed to check for high spots.  I found
out that babbitt is a little less forgiving when there
is moisture under the cap that you a pouring.  It blew
the Dam-tite out like some had set off a firecracker
inside of it.  I only got a little burn on my face and
learned and inportant lesson about proper preheat.  I
can't figure out how you get heat into the shaft when
you are pouring the cap on a bearing with it all
assembled.  The next try we heated the shaft then
installed the cap and heated which was still warm from
melting the bad pour out.  I was trying to avoid
working with the hot pieces but can't figure out how. 
Herr's hoping that I have the crankshaft positioned
correctly.
