Next I measured and made the connecting rods.  Like the side rods, these puppies took about 30 hours to make.  First I started with a hunk of steel and bored holes for the bearings. 

Once I got the holes bored, I machined the face profiles.  Then I taped a copy of the connecting rod drawing to the rod and sprayed it with layout bluing to give me the outline of the rod.  Then I cut away the excess with the band saw.

Here's what it looked like after rough cutting and grinding.

This is how I put the profile on the rod.

I did have to take off some excess metal on the crosshead slide bar to clear the connecting rod when the drivers were at 12 O'clock.
