Chuck:

That is a perfectly reasonable approach to the part. I would suggest that you make the flat piece oversize, and then once it is soldered in place you can chuck the rod in the lathe and face the flat bit to dimension, this will ensure that it is perpendicular to the axis of the rod, and will also shave off the crud that results from the soldering! If your chuck is easily removable, and you have the head-room in your mill , once you have faced the part, leave it in the chuck to sit it on the table of the mill or DP to drill the holes for the bolts that hold on the big end, and to bring the sides and ends down to size.

(That's just how I would do it, many other ways to skin this cat, no doubt.)

Cheers, Joe

Chuck,
It helps to sort out the order of operations, select the most appropriate
tools available and even design and build fixtures that make multiple parts
much quicker and easier. Having an overall outlook on building the part will take a lot of the worry out and keep Murphy from showing up.
Also, posting a specific question here will get an answer or two.
Look at this as a good opportunity to advance skills and add enjoyment
to your hobby. As far as the conrod, I can silver solder the pieces if You
decide to make it in 2 pieces.
Planning for maximum material yield is a worthwhile skill for
frugal people like me and ensures the growth of my offcut pile, which I would be glad to share with team members for this build. The shafting for the crankshaft will be from stock thats been sitting around for over 20 years.
It should be well seasoned by now.

Regards,
Maverick

Chris has volunteered to assemble and auction off one of the engines.
So we need to make enough parts for 10 units.

When it comes time to ship your parts mail 2 sets to Chris.

Ok so the piston I'll make 10-15 thou smaller and the oring will be a nice fit for .500. Will that be ok?

Default Hardware Schdule...

Okay, now that we have a few things out of the way we need make a few more decisions namely:

Hardware ... I suggest that we supply our own. That way each team member can decide whether to make or buy the nuts/bolts and what style.

Schedule ... lots of parts need to be made so how about shipping parts by February 28, 2013. This gives us a little over 3 months. With the holidays coming up we all will be very busy with family, so maybe we should extend it a few more weeks?

Comments ...

That is reasonable time to shoot for.
As for hardware supplying our own is ok with me.
