Bart, it'll be a most impressive steamboat with grace and allure. Lovely lines.

I've given a look at the engine bed: what a chunk of steel! Your engine promise to be a sturdy and reliable one.

Well, I managed to spend a few days in the shop over the last month, and have made some more progress. The engine base has the crank mounted and is supported on a stand on casters so I don't need to lean over so much:
More photos and a very short clip of the crank turning here:

Next up: make columns, column cross-braces, crosshead guide, crosshead slipper, and connecting rod . Should keep me busy for a while .

Bart,

Are you going to bring the engine to B&W for show & tell?

Sure. Just need to hoist it into the back of the truck. W/ flywheel, larger alternator drive
wheel (another flywheel w/ some flat belt grooves ) and crankshaft counterweights, I
think it will be 300+ lbs. If I get the columns in place by then, it may fit; it's
pretty tall on its stand w/ that underslung crank and 2.5:1 rod length/stroke ratio.

Worked on the engine base. Still getting the hang of the 3" face mill; ran it too fast and will be indexing the carbine inserts .
The DRO saves a lot of time.

I'm glad to see you are back at it, Bart.
Now the crank has a home.

I've been modeling the Sea Lion engine in Fusion 360. Interesting learning some 3D CAD, and the price is right - free. Definitely a bit of a learning curve, but after some futzing around I've got basic motion working for the steam engine.

Lots more work ahead, both in design and and fabrication.

Thanks for keeping us updated Bart.
Like others, I escaped school and entered the University of Life, and learned the math I had to. Your planning and design skills impress me.

Hello Bart,

how do you want to mount the flywheel on the crankshaft? I have done that with two keyless locking devices at my HASBROUK #10.



They are prevented from water with two discs.



Technical data you can find here.

Dietrich,
Those are wonderful things and I use them all the time on ready made couplings. In your case did you have to cut your own taper in the flywheel? Was the correct angle of taper provided by the manufacturer?
The next time I remove my flywheel I'm going to change it over. I dislike keyways and screws. The least amount of corrosion and there is a terrible problem.

Mike, I think if you look at the technical data they are double taper, i.e. expand parallel.
