Thanks, all, for the kind comments.
After a brief hiatus to work on my mill / drill and add DRO's on the x and y axes, I got back to work on my engine today. I finished up the two connecting rods. Here in the first picture you can see the fixture I made to hold each connecting rod for machining.
I first milled the edge of one side, then took out the screws, flipped the rod over and did the opposite side. After finishing the edges on both rods, I changed end mills to a 3/16" and milled the groove down the center of each side. Finally, I rounded the outside edge of the small end.
Here are the finished rods...
And an idea of what they will look like on the engine...
The whole process was a good exercise in using DRO's for positioning. Makes for much more precise locating than trying to machine up to scribed lines and marks.
I think I only need to make and install the crank arms to be able to test the engine. And of course I'll need to make a base for it sooner or later.

This really is looking great, love the proportions of it as well as the theory behind it. I must admit, I've only just got around to looking how it works ... should be powerful and sound interesting as it'll have full bore pressure to the cylinder from TDC!

Thanks, Nick.
Well, the good news is that I got the engine together enough to try running it...
The bad news, it doesn't run... at all. Doesn't even look like it's trying. I suspect there is too much binding and too many air leaks.
