For those of you who have been directed here from my Armenia build in the ‘Build Logs for SCRATCH SHIP MODEL PROJECTS’, please bear with me.  For those of you not coming from that build link I will be developing a 3-D model of the Hudson River sidewheeler, Armenia.  Briefly, the Armenia (1847-1886) was built by Thomas Collyer, New York. She had a wood hull with an overall length of 187 feet, a molded beam of 28 feet with an extreme beam of 50 feet with a depth of 8 feet 6 inches. She displaced 391 tons. She was powered by a Henry Dunham vertical (walking) beam engine. The paddlewheels are 29 feet 4 inches in diameter by 8 feet 3 inch wide.  I will be following drawings, by F. Van Loon Ryder dated 1954, 1/8” (1:96) scale, resized to 3/16” scale.  The purpose of building this model is to help me better understand how to actually physically build this model from scratch and to learn 3-D cad.

 

I will be building this model with AutoCAD version 2013.  I’ve used AutoCAD for close to 30 years now but never its 3-D functions.  This will be my first attempt at a 3-D model so all you proficient users of 3-D cad, if you see me doing something really stupid please don’t hesitate to let me know.  That goes for all you steamboat experts also, as this is my first steam powered boat, if you notice that I am making some major faux pas on the ship please let me know.

 

Alright enough talk lets draw something.

 

I started by scanning the hard copy of the drawings and making .tiff files of them.  Those files were then inserted into AutoCAD and scaled to 3/16” (1:64) scale.  Using the Body Line drawing I laid the keel using a polyline and sweep command.

 

KEEL.JPG

 

 

Next I used polylines to trace over the body line cross sections. From these tracings I extruded the bulkheads needed to form the hull.

 

 

bodylines.JPG bodylines2.JPG

BULKHEADS.JPG BULKHEADS3.JPG

 

A little a## backwards with this next step but using the bulkheads I formed the bulkhead former.  Slots were made in each bulkhead with matching ones in the bulkhead former.  These pieces will be used as templates to construct the actual model.

 

BULKHEADS4.JPG

 

Once all the bulkheads and the bulkhead former (BF) were completed I used the ‘loff’ command between each bulkhead to create the hull.  OMG, if real planking could be this easy.

That hull form should not be too hard to plank, when you get to the real thing. Nice start, Sal!

Very cool. I've been wanting to start using AutoCad myself for ship design. I've started to a few times but just havn't found the time to really dedicate to it yet. I think I will follow along and maybe help get myself motivated plus learn a few pointers along the way.

Thanks Elijah, It'd be nice if I could build the real thing that quickly.

Thanks druxey, you're right about the hull planking, there's not too much of it.

Welcome EJ_L, I just recently retired so I have some time on my hands to play around.  There are some nice tutorials on YouTube explaining a lot of the 3-D commands.

Now, because the ships engine will be such a defining part of the actual model my thinking right now is to make room for it in the hull.  To do that a portion of some of the bulkheads, and of the BF will need to be cut away.  The plan is to do cut them out after all the hull planking is complete so the model is sturdier. 

 

This picture shows the area required for the boiler and engine.

Then I thought, to help stiffen the hull, walls should be added to form out the engine compartment, although not part of the actual ship.

I don’t know if this next step is 100% correct but for easy of installing the main deck beams I thought I would run them across the top of the bulwarks and hull in one piece.  The main deck floor beams are 4”x 6” (1/16”x3/32”) and are equally spaced at 2’-4 ½”.  These were made from extruded shapes placed on top of the hull and bulkheads.

 

 

FIRSTFLOORJOIST2.JPG

FIRSTFLOORJOIST.JPG

 

 

 

An 8”x10” (1/8”x5/32”) guard timber was placed around the perimeter of the deck beams and faced with a 2” x 10” (1/32”x5/32”) plank.  Wales were added at the top of the hull following the sheer and deck beam braces were added

 

 

deck1.JPG

 

 

The deck itself was constructed using a surface command and given a thickness of 2”.  For clarity the decking won’t be shown to often.

Elijah, It does go pretty quickly especially when there's a lot of symmetry.  Draw one side of the ship and then just mirror that side to make the other.  To make the parts you basically copy what's on the drawing in 2D and then give it some depth.

Next I decided to work on the paddlewheels.  I started with the crank arm with dimensions taken from the drawing.  I also learnt that the length of the arm will be half of the stroke length.  So with a stroke of 14’ the arm is 7 feet long.

 

CRANK.JPG

 

The flanges for the paddlewheel arms were next. Followed by the shaft.

 

CRANK2.JPG

CRANK3.JPG

 

The buckets (paddles) on the paddlewheel are 8’-3” long by 2’-4” wide.  There are 13 main buckets and 13 intermediate buckets per wheel.  The wheel was 29’-4” in diameter and rotated at a speed of 17rpm.

 

One question I had about the buckets is; are they made of one piece of wood 28” wide or of three planks 9 1/4” wide?

 

PADDLE.JPG

 

 

After making one set of the main and intermediate buckets it was very simple to array (copy) them 13 times around the center hub.  Iron bands were added as shown on the drawings.

 

PADDLE1.JPG

PADDLE2.JPG

PADDLE3.JPG

 

After one paddlewheel was completed it was just a matter of copying it to the other side for the complete paddlewheel assemble

I like this view.

I couldn’t find too much information on what the boiler would look like so I took some artist liberties.  From the drawings I knew its diameter and length, stack location and the stack height and diameter.  I wasn’t sure about the number or location of the doors used to load the coal so I guessed at two.

 

BOILER.JPG

BOILER3.JPG

 

 

I also took some liberties and added a pressure gauge and sight glass.  I always made fun of the designers at work when they added nuts and bolts to pieces of equipment that would never be seen when you printed out the drawing but now I know why they did it, it's fun.

Very nice. Are you going to do a virtual tour of your model when done? If so then all those little details will be visible and really cool to see then. That is one advantage of 3D models, you can zoom in or remove layers to see those hidden gems much easier than physical models.

I have little knowledge of this subject, but would the boiler also have two or three relief valves?

 

This is inspiring work of a superior quality.  Thanks for letting us peer over your digital shoulder.

lovely 3D rendering Sal,

 

Congratulations,

I wish I could do such skilled and awsome designing with aid of my PC....

I read in your introduction to this project that you are having at least 30 years of Auto Cad experience, and that shows...., 

Unfortunately during my active business time I never found someone who was able to describe the way of 3D design thinking in understandable way to me, versa the "old"  three views drawings during my time of career. I believe the 3D design is a complete different approach in thinking is`nt it ?

 

Nils
