It is finally done! This is a PM research No. 1BI cast iron kit. I started this engine back In March, and it has consumed most of my free time since then. I lost track of the number of hours put into this engine, but it has to be over 250.
This is the first build I have ever done on this site, and I found it to be a very rewarding experience. Building it in public like this really pushed me to pay attention to detail.
I made a few special touches that make the engine uniquely mine:
1. The head and steam chest were machined from brass bar stock rather than the cast iron parts that came with the kit.
2. The crank is built up with counterbalances rather than the cast iron original.
3. The crosshead slide standoffs are not the simple cylindrical shapes in the plans.
4. the valve link is a one-off design.
5. Custom made hardware to replace the slotted screws that were supplied.
The Build log can be seen here:

Now for the pics:
...and of course, here is a video. (It gets a bit long but I do show both sides )

Thanks so much to all of you who followed along on the build. Your shouts of encouragement meant a lot along the way!
