Very nice work and right along the lines I plan to do.
I've already bought & paid for a Bridgemill from Chicago Lathe to be shipped to me in the Philippines. Once I have my new shop built I'll have it shipped and also buy a 3D printer and a laser cutter/engraver. Lifting will be far less than what I use to do.
Where did you find the prints? I also plan to subscribe to Model Engineering once I've relocated.

I found the plans on EBay. They are very well done and fairly easy to read!

Tonight’s quick machining job on the Bar Stock Steam Engine build is the stand offs to mount the Cylinder and the Valve Body to the base. They are machined out of .250 brass round bar. I needed a set of eight .750 long and eight 1.250 long. I started off by cutting the stock on my bandsaw just a bit longer then required. I faced the first side, centre drilled, and drilled the through hole on all the pieces first. Then I faced the second side, measured length, then took them all down to finished length.
I figured doing it this way was the closest process to a production run with the least amount of changes. I have several drill chucks for my tail stock. So I have the centre drill in one and the required drill bit in the other. Worked out pretty good. All 16 pieces done in 45 minutes total!

Making identical parts is one of the biggest challenges for a hobby machinist. Congratulations on a successful job.

I plunge cut between the clamps leaving 0.030 extra material to remove on my finish passes.

Once I had all the material plunge cut between the clamps I played musical clamps. Removed one clamp at a time to remove the material that was under the clamps.

I then found out that my sacrificial plate under the brass should have been smaller. The amount of excess out past the part now made it impossible to get the clamp in far enough to reach the part. So I had to locate the top of my rotary table and plunge cut the sacrificial plate. I stopped .010 short and just broke the excess off by wiggling it back and forth. I was really nervous about marking my rotary table. But it worked out perfect!
