I too have been following this thread, but haven't said anything yet. Steve, this is truly a wonderful model, and your work sets the bar a little higher for the rest of us! Thanks for the excellent photos and the video, too.
this morning I completed the last 2 linkage pieces for the boiler feed pump and did a video of everything working. sorry It's a bit shaky and a lot of air noise, I just pushed a hose in the regulator and it pops out at the end of the video. I'll start on the boiler, valves and plumbing next. I ordered 1000 rivets......
here are sites with information on the original mill builders and the Yulee Plantation where it is located.

I have started to make the T's, valves, and flanges for the plumbing. this is hard trying to just solder one point and not have everything fall apart. I'm to shaky for this stuff I did find brass castings of some of the fittings, I just have to machine out the center holes. There are a lot of parts left to make, pressure safety valve, several check valves, smaller gate valves, several valve handles.....
some of this will be real and some is just for show, the mill will be running on air.
the plate in the pictures that the valves are on is the front of the boiler, I haven't machined it out round yet.
thanks for viewing

today I made the pressure safety release valve and started laying out the drawing to drill 516 rivet holes in the boiler housing.

Today I drilled the rivet holes in the boiler tube. I was amazed to see my mill drill 516 holes .062 in diameter in 1 hr and 20 min. Ya gotta love CNC. the next surprise was it did it with only 2 harbor freight bits...
today the rivets showed up in the mail, 1000 of them and they are not .0625 they are .060 so I have to swedge the shank of everyone of them to make them drive in. more fun
