I was wondering the same thing. Was also waiting to see if you show up again.

There were eccentric rods on either side of the engine that once the ship was under way would be engaged onto a rock shaft which operated the steam intake and exhaust valves (more on those to come).  The eccentrics are connected to the paddle-wheel shaft and have off-centered hubs which produce a back and forth movement in the eccentric rod.

This is how I believe the eccentric rod mounted to the eccentric.

HI Bob,

Where have you been? We miss you at CMMS.

Best,
John

Thanks John, Joe,  miss you guys too.  Work has just been taking most of my energy lately--I've been making a lot of stuff, but all client work--I haven't touched my models in far too long.  Meanwhile, I'm enjoying watching Sal and the rest of you doing wonderful things...

The engine is made up of a few major parts.

 

cylinder8.JPG

 

The first part that I modeled was the air pump.  The air pump was connected to the condenser and was used to draw off the condensed water and steam vapor.  This was fairly simple to model as a cylinder with a piston rod.  The air pump was operated by the two slimmer connecting rods coming down from the walking beam at the beams quarter point.

 

CONDENSER.JPG

 

Next I started on the main engine which is comprised of the condenser, cylinder for the main piston rod and the live steam and exhaust steam pipes. 

 

cylinder1.JPG

cylinder2.JPG

 

Next I modeled the valve lifters for the live steam and exhaust steam.

 

cylinder3.JPG

 

The valve actuating mechanism consisted of a set of large, curved cams called “wipers” which worked against followers called “toes” which were affixed to vertical rods going to the steam and exhaust valves at the upper and lower ends of the two cylindrical vertical steam pipes. The drawing of the engine did not clearly show how these cams were laid out but I did find a good reference.   It was on goggle books called “Marine Boilers; Marine Engines; Western River Steamboats”

 

https://books.google...epage&q&f=false

 

Even with this diagram I still ran into a little interference with the cams. It’s not clearly shown in the diagrams but I believe the outer cams must have had and offset to operate correctly.

 

ROCKER2.JPG

ROCKER3.JPG

 

Completed valve actuating mechanism.  The lower smaller cams with the starting bar was used by the engineer when first starting the engine either forward or in reverse.  The rock shafts were two separate shafts supported in the center by a common bushing.

The pressure gauges and clock layout was plagiarized from the Ticonderoga.

Elijah, it's easier than it looks with cad software.  First you make one, rivet or nut, then just copy it as many times as you like. If their in a circular pattern there is a command called 'Array' which will evenly distribute copies of an object in a circular pattern around a center point.

To put things into perspective I added a couple workmen to give an idea of how big these engines were.  The upper figure is on the ship's main deck and the lower figure is below deck.  I cannot take credit for drawing the 3D man, I borrowed them from my former place of employment.  The person is roughly 6 foot tall.

Wow Sal that's a tremendous piece of machinery. However are you going to transfer that into a model? Could use one of those puppies for

my Portland if I ever get that far. See you at the next meeting.

Hi John, I'm not sure I'll be able to model the complete engine, I sort of get carried away doing the 3D drawing. It's more of a learning experience now than anything else.  I'll see you at the December meeting, I'll be on vacation for the November meeting.

It’s been a while since my last post.  It just seems I’m busier now after retiring than I was when I was working full time.

 

Working on the rudder to try and finish up the hull.

 

RUDDER98.JPG

 

Started with the gudgeons and pintles

Next was the rudder itself.  It appeared to be constructed of individual timbers.

Rudder post and steering post added

Finally the steering chains and rudder stop chains were added.  Fortunately I found a ‘lisp’ program, which runs inside AutoCAD that actually draws the chain links along an established line.

Beautiful cad drawings Sal~!  Enjoy your vacation and see you in December.

 

BTW,  when you get to building the engine, the eccentrics would would be offset 90 degrees so as to prevent a top dead center problem, that is the engine would not start.    

 

Nice work!                            Duff

Hello all,

 

Back from vacation and finding it hard to get back into drafting up the Armenia, perhaps after the holidays.  There is something from our stay in Florida that I would like to share.  There was a sand sculpting competition at the beach across from our place and it's the first time we were down there when they had the event. I have to say I was truly impressed by with the amount of detail put into these sculptures. All the sculptures are 7 to 8 feet high.  If you would like more information here's the web site:  https://www.siestake...talclassic.com/

 

Just a few of the dozen or so sculptures
