Kirk,
It's a good thing you locked the shop elves out cause they'd have a field day with those small parts. Looks great, runs great.

All put back together.  I tested that it ran before adding the governor stuff, so once I get around to shortening a bunch of 0-80 screws I should be able to call this one done.

Not in a diorama, nor do the governor or pump actually work, but the end result is the "look" I was after.

This will be delicate to take to CF.

Looks great!

For travelling, can the flywheel be removed to take off the weight of it from the rest?

I can remove the flywheel and governor.  Probably need a box with foam padding for the rest.

That is a very nice looking engine. I like the balance of brass to other materials.  :ThumbsUp:

I'm going to revive this thread.  Nine years of sitting in the shop has dulled all the brass, and I never did get around to shortening the 0-80 screws, along with some others that are too long.  My current plan is to powder coat the aluminum along with the cylinder, as I no longer like the 20th-century look.  I also discovered that the top of the column has loosened, allowing it to rotate out of alignment.  So a complete disassembly will be needed.

The good news is that my workbench is now clear for the first time in years, meaning i likely won't lose any pieces.   8)

Surprising how fast time goes by, my Pacific is still waiting for paint and wood work. :lolb:

I've always fancied making one of these engines, it on my 'future' list - it looks great!  :popcorn: :ThumbsUp:

I disassembled the engine, and then put the first parts to be powder-coated in the sonic cleaner to degrease.

Likely won't actually get to the coating part until Sunday at the earliest.

Started on the sub-base and initial did timing.  Timing is probably off a bit, but I'm doing some run-in before any tweaking.
