I've had little time to devote to this over recent days but finally got all the pieces together. However, there's quite a bit of binding and it's really difficult to turn over by hand without a flywheel! I resorted to removing one crank disk at a time and replacing it with a temporary flywheel. It's possible to turn it over when one side or the other is connected but not both  I can see this is going to take some time to sort out let alone trying to get the timing right. Ho hum.

Throttle levers look good, as do the Thew valve guides!   
You're getting close, Chris!  Just the valves left to go? Is that right?

That Gothic beam at Henry Ford is a must see I'm person......it one of the several engines there that will melt your mind......watching (and hearing)  the valve linkage on the Corliss is amazing

HI

I found a source for a walking beam marine engine from the Mariners Museum and Park in Newport News VA. They have a ton of material 40 sheets, and they quoted sending scans and photos.  The cost was  $800 so for now im waiting and I think Ill spend that on a trip to the Museum, make dontation and browese the archives.

In (I think 1852) edition of 'The Steam Engine' by Thomas Tredgold, fully detailed drawings of all the major components for the walking beam engine 'New World' were published. I have scans lurking somewhere on my computer. if they are of any use, I can post them on the site or email the folder. Bear in mind, when I scanned them at the British Library, they wouldn't stay flat, so look a bit 'wavy', but all the relevant dimensions are on the drawings. There's 34 scans (some of the pages where scanned a couple of times to make sure I got all the detail) at about 1.2MB each so I assume I could only send them via the cloud? I am a Luddite at heart, so don't really know

Thanks, Bent! 

Yes, sanding & polishing is what I'm doing now.  Not a fast process...
I'll post pics in a couple of days.  Tomorrow's not a shop day.
