Today started in all the milling/drilling/tapping work on the parts, started by milling the flats on the center ring, one side a narrow flat with holes for the connection to the swing gear later on:

and the other side a wide flat for the steam chest. That side has holes in the side of the ring, so the steam chest can be notched and side drilled for the mounting screws. Don't want to bolt through the chest, since that would interfere with all the other passages and ports.

Also drilled/tapped the cylinder end and rear cap:

That means I can get started on the shaping of the front flange/cap, which has also been cross drilled for screws to hold it to the end of the cylinder. Lots more to do at that end...

Started in on shaping the front end cap today. It has a tall ridge across the middle to take the guide rods, so started with a thicker piece of the bar and milled off the sides. Since it wasn't that deep in the chuck, the mill had a tendency to rock the part while cutting, so I put a bar across the middle to hold it down flat. Both sides were taken down the same.


Then drilled the mounting holes while it was still in the chuck and aligned:

With the mill table still locked down in that position, switched chucks and drilled matching tap size holes in the end flange, lining up the holes so the center ridge in the cap will end up horizontal.

I'll get those holes tapped next, then continue on with the shaping of the cap...
