With your deck weathered to match the real thing, I had to look twice to tell which pic was the model and which was the 1:1 ship!

Thanks, Matt.  If you look back at older pictures, my deck was much darker.  I sanded it down to lighten it up, and fortunately, it ended up with a good weathered look.

 

Now the question is whether I should move on to the bits I really want to do (all the stuff on the deck), or the bits I don't want to do (headrails and figurehead)...

I have completed the head rails, head timbers, and cheek knees.  I found it best to work on the cheek knees first, and head rails last.  It was necessary to make several parts in multiple pieces, as the shapes were too complex to model as one.  I also attached the printed nameplate to the outer bulwarks.

Here is the 3D design for the various 3D printed parts.

For the curious, here is how I created the shape of the headrail in Fusion 360.

 

I started by creating a construction plane which passes through the underside of the cathead at one end, and through the stem at the other.  On this plane, I created a sketch and drew the curve of the headrail.  This curve passes through the center of the eventual part.

sultana_build_log_051_05.jpg.47d867ddbba9d12351e62b673aed7fef.jpg

Next, I created two construction planes.  The planes are tangent to each end of the headrail curve.  On the planes, I created the start and end shapes for the cross-section of the headrail.  In this case, a 3mm x 3mm square at one end and a 1mm x 1mm square at the tip, highlighted in blue below.

sultana_build_log_051_06.jpg.e8bef9f3a9a7a2324a1c4886802c98f7.jpg

To create a shape, I used the loft tool.  Initially, the loft connects the two profiles via a straight path.

sultana_build_log_051_07.jpg.26b41dff9edd77f99365c4dea8ae96b4.jpg

In the loft dialog, I changed the guide type from tails to center line.  I selected the headrail curve as the centerline, and the curved shape is created as I wanted it.

On the Sultana, lifejackets are stored in containers at the sides of the main deck.  These are arranged to resemble hammock storage, with rails and netting around them.  The picture below is my own of the lifejacket storage.

sultana_build_log_052_01.jpg.9b518ecb1049334be88c38948a2f0d45.jpg

I tried several methods of creating the shape of the lifejacket storage.  The top shows an attempt using modeling clay.  The lower attempt was using blocks wrapped by fabric.  I was not happy with either result.

sultana_build_log_052_02.jpg.67d8791478ff8a8c9f2bba04cdb23813.jpg

The method I settled on was to create a mold of the correct size, fill it with modeling clay, then press fabric against the side, giving it an imprint of the fabric texture.

sultana_build_log_052_03.jpg.71773495c70dff84e76228540ff934e9.jpg

The metal rails were designed and 3D printed.

sultana_build_log_052_04.jpg.29f1e3e8e19cbc4730ed4b8a7826b07d.jpg

All the pieces were assembled and wrapped in netting, which was produced using the method I have described earlier.  Bars across the top were added.

sultana_build_log_052_05.jpg.8495eba1500c29d9effc65bfb61dcff2.jpg

I was mostly satisfied, until I saw this photo on ship25bsa.smallsquareddesigns.com which shows that I omitted the covers.  The covers wrap over the outer bar and on the inside is a hanging flap which identifies the contents as lifejackets.

sultana_build_log_052_06.jpg.a2cc707b64e92a5f781df760b80aecfb.jpg

I went through the fonts on my system and was pleased to find that I already had the correct font: Gabriola italic.  The covers were printed on paper and glued on to the model.

I have been looking at publicly available 3D models in order to find a suitable figure that I might use as a starting point for modeling the Sultana's figurehead.  This guy, "Standing figure of Alex" by user thowe on Thingiverse, won't help for the figurehead, but I thought it might be nice to have him available as I work on features of the deck to validate the scale of the pieces I work on.  I scaled him down to 1:64, and printed him out.  Expect him to appear in future installments.

Let's build the windlass, starting with the ratchet gear.  After studying a number of pictures of the Sultana's windlass, I determined that the ratchet gear has 12 teeth.  I created a 12 sided polygon and added one tooth.

sultana_build_log_053_01.jpg.99b86c6d9c52cbf721233e89816ff180.jpg

Then I used the circular pattern function to copy the tooth for a total of 12 units.

sultana_build_log_053_02.jpg.a3bdc56305f7e442f16d6395aeec5381.jpg

An extrude operation created the final shape of the ratchet gear.

sultana_build_log_053_03.jpg.098f3ac3f559859a3525e4b5f4dce4eb.jpg

Adjacent to the ratchet gear, I created an octagon, then a second smaller octagon the correct distance away.

sultana_build_log_053_04.jpg.15198b79318c06f402fa3bf4a0f90ee7.jpg

I used the loft function to create a shape between the two octagons, then mirrored that shape to the other side.

sultana_build_log_053_05.jpg.890e513b130748213730bb3bd30c8cff.jpg

The holes were added and both rectangular and circular patterns were used to place the holes around the windlass.

sultana_build_log_053_06.jpg.7743a891ff70ab9c644d91d3ffb773e2.jpg

And finally, the supports were modeled.

sultana_build_log_053_07.jpg.a7ef8842826602c00921024e45e08408.jpg

All of the windlass parts were 3D printed.

sultana_build_log_053_08.jpg.84b79220f808cfdd89bda600eb1c5563.jpg

The windlass pawl and galley stack are connected.  Here is a picture of the galley stack.  For now, I have decided to omit the white cover on the galley stack.

sultana_build_log_053_09.thumb.jpg.f7d0ef7adcf1f9e6dd82280663c37b07.jpg

This is the galley stack 3D model.

sultana_build_log_053_10.jpg.fc06d4f33dd8678d7e2424d0a392250b.jpg

And this is the 3D printed part.  I used some burnt sienna paint to indicate rusting.  (There is no rust in my photo of the galley stack, but it is present on other photos I have found.)

The windlass and galley stack glued on to my Sultana.

This details building the ladder.  First, one side of the ladder is created.  The fillet feature allows the ladder to be rounded off at the top.

sultana_build_log_054_01.jpg.3965ff0e1fa446b21a861b95e618c9f7.jpg

One step of the ladder is created, and a rectangular pattern operation creates the remaining steps.

sultana_build_log_054_02.jpg.e960e9f397fa9f46e5d668a709638a9c.jpg

Extrude the steps and add a copy of the side piece, and the ladder is complete.

sultana_build_log_054_03.jpg.9671e76d9f6f60e6fdb8968b01da2d6c.jpg

Using a knife, I scribed some lines into the 3D printed part to simulate wood grain.  The piece was painted a wood color followed by a brown wash to enhance the texture.

sultana_build_log_054_04.jpg.a84352b34bc359a7586f1a8408612bf3.jpg

And finally, the ladder is glued into place.

This is turning into a plastic model..... 🙂

I know.  It's been an interesting experiment, to see how far I can go with 3D printing.  I'm not aware of anyone else who has tried making a wood / plastic hybrid like this.

The Sultana has four hatches.  Two are small: one is located aft of the windlass and the other is forward of the binnacle.  A long, medium sized hatch is on the quarter deck, and will be open to expose the ladder on my model, as it is on other Sultana models.  Finally, there is a large hatch on the main deck.  Most models depict the main hatch covered with boards, but on the Sultana replica, the large hatch has grating and a ladder down.

 

The picture below is of the medium hatch, with the grating in place to cover the ladder.  Note the white cover.  All of the hatches on the Sultana have these covers, which keep out water.  However, I think I will omit the white covers.

sultana_build_log_055_01.jpg.75a369d79b4b94c89567a896f2607f20.jpg

Creating a grating in Fusion 360 isn't too hard.  Draw a rectangle, draw one of the square holes, use a rectangular pattern to create the remaining holes, then extrude the sketch.

sultana_build_log_055_02.jpg.759c4fed45dc8264492d82e3f2c94435.jpg

For the grating on the Sultana, I need to have the holes and space between holes at roughly .6mm in size.  I ran an experiment to see how small I could make grating that still retained square-shaped holes.  As you can see, the pieces in the lower right are acceptable, while the ones in the upper right are not.  This shows the limits of what I can do with 3D printed grating.

sultana_build_log_055_03.jpg.42c3011a7258f34279efcfcdd31cd738.jpg

After some experimenting, I found that having the surface raised in one direction makes the grating look better.

sultana_build_log_055_04.jpg.9b1c5bdf057b9376942e9bd6031cfcfa.jpg

Next is the hatch coaming.  From my earlier work, I already knew the exact curvature of the deck camber.

sultana_build_log_055_05.jpg.9d3c63ce0e8532a87f0d7d9f955bd415.jpg

From there, I created the profile of the coaming.

sultana_build_log_055_06.jpg.79a4ec7de748d885ec4843816bc6de80.jpg

And then the profile was extruded.

sultana_build_log_055_07.jpg.49c91956e5c596ce5e149e5fc11f811d.jpg

I created a new sketch on the coaming surface to indicate where the recess is.

sultana_build_log_055_08.jpg.b09e3f43c5baff1ccf712b5eed117f48.jpg

And the relevant parts were cut out.

sultana_build_log_055_09.jpg.fa256e7f0124ad7f0645ccf97c1c02b5.jpg

After 3D printing and painting, here are my final hatches.

sultana_build_log_055_10.jpg.3c7bcc367914e12cc2673d3089bee7b8.jpg

And here are the hatches on the model.  The aft-most small hatch hasn't been glued down yet, because I need to place the binnacle first, then glue the hatch an appropriate distance from the binnacle.

I started work on the binnacle by creating a 3D design with the lid on.

sultana_build_log_056_01.jpg.3356f5362792a8f93b9cebd27eeb7c9b.jpg

This was not bad, but a bit boring.

sultana_build_log_056_02.jpg.22820928f9bbaefa9df1b054dbf9f0c8.jpg

The best picture of the open binnacle I have found is from ship25bsa.smallsquareddesigns.com, which has been a great resource for reference photos.

sultana_build_log_056_03.jpg.e15a38cbfd49746501e152c20f416585.jpg

I first tried adding the details of the instruments as raised parts of my 3D design, but it was beyond the ability of my 3D printer to render them in sufficient detail, so the result was just little plastic blobs, which were made worse after painting.  My revised design replaced the instruments with a little piece of paper.

sultana_build_log_056_04.jpg.44493d74bf488e732c7b19978853874e.jpg

Testing the binnacle on the model.

sultana_build_log_056_05.jpg.476a779a694781860a3ac7b84f220f37.jpg

And finally it is glued on and tied down to rings on the deck.

I, too, have mixed feelings about all of these modern necessities on replica tallships, but there is no question that you are doing a bang-up job of replicating the vessel in her current configuration.

The pumps on the Sultana are quite beautiful, particularly in the long curve of the handles.

sultana_build_log_057_01.thumb.jpg.599e6fcd1aaf95248f144d5b3b1653d4.jpg

Here is the initial 3D design.

sultana_build_log_057_02.jpg.2f40a567a516cf0da66690b400998dbf.jpg

I 3D printed parts, painted them, and tried them out.  They were good, but looked a little too tall.  Also, the interesting transition from octagon to square at the bottom wasn't distinct enough.  I revised my design and created a new set.  The old version is on the left, new is on the right.  The new pumps also have wire out the bottom to help hold them in place. 

sultana_build_log_057_03.jpg.ec32f630662ed0b4b20f7e93cc4c9c53.jpg

Here are the pumps installed on the deck.

Work on the details of the Sultana's hull is nearly complete.  Soon I will be moving on to the masts, spars, and rigging.  Here is what the Sultana looks like now.

sultana_build_log_058_01.jpg.822532e7ce94d1a120b6e11d3ef23119.jpg

Actually, that's the real Sultana back in December, when her masts were removed for maintenance.  The picture is from the video Winter Maintenance on SULTANA’s Masts.

 

Here is what my Sultana looks like.

sultana_build_log_058_02.jpg.78d5ed0d9da2b417116ed0f04999e7fe.jpg

Details that have been added include:

  • Rope railing and white cover on the main hatch.  I was originally planning to omit these details, but the hatch looked too plain as it was.
  • Metal, oval-shaped mystery hatch at the bow, port side.  Maybe for refueling?
  • Box for storing propane gas at the bow, starboard side.
  • Various eyebolts and cleats.
  • Additional signage on the hatches and opposite the ladder.

sultana_build_log_058_03.jpg.ef62f54ad90cafc5874473f3e48242d3.jpg

The next steps include understanding and planning out the rigging, and making the figurehead.

I developed the figurehead in Blender, as I haven't been able to understand how to work in the sculpt environment in Fusion 360.

 

The legs were relatively easy, just a matter of drawing the outline as they intersect with the plane of the ship's stem.  Then I built the rounded form out.

sultana_build_log_059_01.jpg.b9dd24f16aea6361bdd37597fca87aa7.jpg

For the head and body, I used the reference images to find contours and borders.  Working from those, it was a matter of building the form out, vertex by vertex, face by face.

sultana_build_log_059_02.jpg.50d0a10a497f66ceee85d8fbde94431f.jpg

After several restarts, I ended up with the best shape I could.

sultana_build_log_059_03.jpg.a001abe765b231c8c75b98616d9f87c8.jpg

I included the shape of the ship's stem in the 3D environment, to confirm that the figurehead would work with the actual dimensions of the model.

sultana_build_log_059_04.jpg.32313788ecfb857102b700e8915f6beb.jpg

The final 3D printed part was so small that many of the details of the 3D model were lost.  Oh well.  I painted and glued on the pieces.

sultana_build_log_059_05.jpg.40c95485f39d0069bcfe5fcb0ef7b53c.jpg

It could be reasonably argued that using carved wood or clay or something else would have produced a better result, but I'm satisfied with my work here.
