USS Constitution by Kirby Francis - Half-hull - Scale 1:192 From AJ Fisher Plans


Recommended Posts

As a preliminary caveat to this log, please understand that the builder is a novice, and that numerous searches online for a faithful half-hull rendering of Old Ironsides have turned up few usable results.  I deeply appreciate advice, and most of those who read this will probably be able to teach me something I don't know!

 

This build log is for a half-hull rendering of the USS Constitution.  I am using the AJ Fisher 1:96 plans, scaled down by 50%.  The plans were purchased from the owner of the company, who gave me his permission to make a reduced copy for this purpose.  I will be using a "lift" method of construction, with an appended keel, sternpost and rudder, and stem.  The degree of ornamentation beyond that is still undecided.

 

I plan to make two models of this sort - the first is a prototype and a test using Douglas Fir from Home Depot - I have given myself permission to make as many mistakes as needed in planning, build process, and execution on this first attempt.  

 

The second model is a gift for a family member who will be retiring from a lifetime of building ships for various companies, most lately the US Navy.  All of us have had a "favourite uncle", and it's a delight for me to make something meaningful for mine.  Our family comes from multiple generations of shipbuilders in New Brunswick, Canada, and model shipbuilding is my way of keeping that craft alive for my own children - albeit in a far humber fashion.

 

So, with that said, on with the Log!

 

***Edit: It turns out the AJ Fisher plans are 1:96, so this is actually 1:192 scale.  My apologies for not checking before posting!  Edited the topic title as well.

Planning

 

The work I am currently doing differs from my original intentions for this model in two ways.  First, I intended to make the ship at the scale of 1:98 so nicely represented in the AJ Fisher plans.  Listening to the tales of many of my fellow club members at the Merrimack Valley Ship Model Club, however, has persuaded me that bigger models aren't always appreciated by those needing to downsize their homes during their retirement years.  With an adequately sized mounting board for this model, building it according to the original scale would require over a meter of wall space - an albatros of a gift.  So, the first compromise was to reduce those plans by 50%.

 

The second compromise was to build the ship from Douglas Fir, not oak.  I have long had the intention to paint the model, instead of using dressier hardwoods and finishing them naturally.  I have built half-hulls with Cherry, Walnut, and Mahogany, and really enjoy those woods.  The look I am going for here is more a representation of a ship, and less of a "builder's model".  The art of half-hulls seems to encompass both ideals, and a choice had to be made.  A friend from our club works on the actual USS Constitution, and shared with me that the famous Live Oak on the exterior of the ship does not extend far inside.  Most of the actual deck planking is actually Douglas Fir, chosen for its excellent rot-resistance, and far lighter weight than oak.  Her current refit has entailed using plenty of both.  So, I feel somewhat vindicated in my choice.  I was able to find some excellent quarter-sawn Douglas Fir at Home Depot, which means I can reduce it to 1/4" slabs for the lifts with less fear of warping or cupping.

 

The hardest part of this act of interpretation is to know how much detail to include.  Perennially a choice with model shipbuilding, it comes greatly to the fore in the half-hull medium.  I have greatly admired the "flying dutchman" half-hull made by friend and member here, Tony Mallia.  It is fully rigged, and so accurate that there is a half-range for cooking in the half-galley!  On the other extreme, some half-hull interpretations of Old Ironsides include almost no detail.  For example:

 

uss-constitution-1797.jpg

 

I wish to find a balance of detail.  Trailboards, stern gallerys, gunport lids are all up for debate.  Some half-hulls will include chain plates and some deadeyes.  These plans are still up for consideration, as begin simply getting the hull assembled, and faired.

Stock Preparation and Templates

 

Having decided to use a lift method of construction, I reduced the Douglas Fir 2x6 (left over from building a picnic table, in fact) to 1/4" planks.  This was accomplished using a resaw blade in the bandsaw, and then a shop-made thickness sander.  In the picture, the thickness sander dust cover sits behind the roller.

IMG_8063.JPGIMG_8064.JPG

With the main stock for the ship prepared, I glued cutouts of the station and lift templates, from the plans, to some scrap 1/4" plywood, and MDF I had in the shop.  I went over both heavily with some spray poly, to keep the MDF especially from furring over time.  The plans were cut out at the bandsaw, and tidied up on the disc sander, and with a shop-made Dremel "router table", with a sanding attachment in the Dremel.

 

With the stock and templates ready, it was time to align, and glue up some lifts.

Gluing Up the Lifts

 

Using the station lines from the lift templates, I transferred station line numbers to the sides of the wooden stock as I traced the lift outlines to each one.  Lifts are lettered A-I on these plans.

The astute observer will note that this novice has already made his first serious mistake - the stern of the ship was meant to the on the left side of the mounting board, as per this page of the plans.  Ooops.  For the next one, I can reverse the lifts to orient it correctly, as you see below.  Also, I was not satisfied with the fit of lift "C" - the stern side of it has too little material, which may be due to movement during glue-up, or an incorrectly numbered station line on the back of lift.

Carving the Hull

 

On the three previous half-hulls I have made, I have essentially glued up blocks of material.  I use a bandsaw to cut the sheer, the outline as seen from the top, and side profile of the hull, and then hog out the mass of material until it gets close to the station lines.  There is far less mass of material to move here.  And what is there to remove seems to love splintering under the chisels and gouges.  There's a reason not many models are made from Douglas Fir, it appears.

 

To carve, I hold the template up to the side of the hull at the correct station line (station lines are on the back, or flat side of the hull, and pulled around to the deck on top as well).  I then use a chalk pencil to highlight which lift needs material removed.  I run up and down the stations of the hull with these marks, then carve a bit.  As the template touches more lifts, more get marked to have a bit of material removed.

After some preliminary carving, it was time to mount the model to a temporary backboard.  This allows me to secure it in a vise for carving, and carve right down to the rabbet line, etc.  Good 'ole 3/4" plywood fits the bill nicely.  I sanded it flat so the half-hull will sit on it in the same way as the intended mounting board.

IMG_8071.thumb.JPG.16a98d4297116727560e2959774fb455.JPG

On the backboard, I can use a square to make sure my templates are hitting the hull parallel.  By aligning them with the right lift, I can ease them down until they make contact.  Then it's the same process as described above:  mark with a chalk pencil, and carve.  

IMG_8070.thumb.JPG.348cc0aa40601fcee01be7f232b84ce2.JPG

I'm finding that for some areas, my finger plane (which has a concave sole and blade) is helping.  Otherwise, it's 3/8" and 1/4" gouges, and occasionally chisels and card scrapers to even out the mess.

A friend at the ship club resized Chapelle's plans for the President to 1/192 for me, and the reference information is valuable in adding details to the AJ Fisher plans.  At times, they disagree.  For instance, I am currently working on the profile of the half-hull at the stern.  Notice on the Fisher plans that the hull line which meets the sternpost actually arcs towards the keel, whereas it is straight on Chapelle's.  

 

IMG_8156.thumb.JPG.ca73a9766436965798e6c2d18b2126cd.JPG

 

Differences like this help me make more conscious decisions.  Little by little, I'm finding that the reams of information on this ship can be used to clarify choices, instead of paralyzing me as a modeler from making them.

Wonderful job indeed.  I appreciate the sentiment for the one you care about.

I plan on making a half hull model of the clipper ship Sovereign of the Seas for my study/library.  I did, however, make a half hull model using one half of a broken model of the Revell 1/96 Constitution.  It worked out very well and it was nice to detail out the chain plates and deadeyes with metal and wood parts.  I have no images of this build because it was so long ago and I never thought to take images.  It was given to a friend.

 

I'll enjoy following your log.

Thanks, Rob!  I appreciate your insight.  While I hope to keep her hull as close to the plans as possible, having some ornamentation like chain plates, deadeyes, trailboards, quarter galleries, etc, might make up what she'll be lacking in perfect lines.

Thank you!  Yes, the thickness sander built for instrument tops, backs and sides works well on wood for scale models, too. As does the feeling of being completely out of our depth at many stages of a project. 

 

My biggest gripe with the Fir is that even finer tools tend to rip out wood between the annular growth. The difference in density between the rings and softer wood between makes it tough to work with cutting tools.  With it being painted, I think poplar would be a good choice, but for some other constraints that require Fir for this one.

If at first you don't succeed as a wooden model shipbuilder.... at least your efforts are combustible.  And there's something to this idea of learning from failure.  As it turns out, the Harvard Business Review once published some great articles on that subject.

 

I had some time on Saturday, so I sat down with the AJ Fisher plans, the Chapelle plans, and a very strong cup of coffee.  What I realized, after carefully checking the hull to the plans, is that I had taken off far, far too much material in the transom area. You can see this when I compare the hull to the second to top lift, "H".

IMG_8302.thumb.JPG.ae221a2d1a9455507bc0d47e16205f03.JPG

What happened?  Well, as the article referenced above puts it, there was an entire "Spectrum of Reasons for Failure".  To be charitable, there are few half-hulls of Old Ironsides out there, and most seem to be built with some kind of moulded hull, or plank on frame.  On the other side, I'm also an inexperienced ship modeler, so some of my cuts have gone awry, and too much material was trimmed off both fore and aft, even as the relative contour was kept.

 

I have heard many experienced model makers talk about that point where they knew they needed to abandon an attempt, and start over.  This first, lift-based attempt may not go in the furnace just yet, but it is going to be set aside.  I am going to start over with a solid block - a carving situation with which I'm more familiar from the other half-hulls I have made. 

 

Here is the block mounted, with a carefully rendered hull copy, from the plans.  Note that I actually have her bow pointing the right way this time.  We're already doing better.

IMG_8303.thumb.JPG.e5e91afb9f9c84398d8b2622542792fa.JPG

As HBR puts it, "A process composed of many elements breaks down when it encounters novel interactions".  Put another way, there are enough "novel interactions" in this build for me as it is.  The lifts ended up being 1/32 off by lift "D", and then 3/32" off by lift "H", making things harder to align with the carving templates.  This time, the lift and station lines were precisely scribed to the mounting board, and I can have a more true reference while removing material.

IMG_8305.thumb.JPG.60f33902e47aff7522a166f4918e8000.JPG

 

One of the comforting elements of that HBR article for me is the suggestion that we ought to own the correct responsibility vis-à-vis failure.  It is not our responsibility to never fail.  It is our responsibility to surface, admit, and analyze failure.  I'm not saying that I will never return to the lift method for this, but for now, I am going to restart with a clearer sense of how to keep the correct length for the hull, and hopefully minimize unnecessary complexity.  And, I have a spare hull now to experiment on with various looks for chain plates, trailboards, etc.

 

Back to the chisels, gouges and planes!

You've picked up some good philosophy, Kirby.  On the plus side, you caught the errors early before putting in more effort.

Well, it's certainly been a while on this one.  So long, in fact, that I think I made significant (and unreported) progress on the new, solid hull blank.  I put it away about a year and a half ago, when my business really started taking off.  Surfaced this the other day while reorganizing the workshop:

IMG_1944.thumb.JPG.cca763e2bfec53ea2b0e3ed29c7a41da.JPG

It's pretty close to the dimensions it should be.  Which leaves me to reconsider my plan for the keel, sternpost, and rudder post strips underneath her.  I have decided not to do the railing details on top.  Leaning in to the historicity of half-hulls as builder's tools, the ornamentation isn't really necessarily, and may actually distract.  Certainly open to suggestions on this!

Kirby,

From 1:96 to 1:192 is reduction to one half in three dimensions.  The volume difference is that  your model will be 1/8 that of one built to the plans.

!:96 is already partially miniature and 1:192 is decidedly a miniature scale.  This will require as much art as it does technical skill, if not more.  You will need to be creative in your choice of materials.

I see this as work on a different plane from most of us.  The production of gems.  I find the prospect daunting.

Thanks, Jaager.  It really is a challenging scale for this model, at least for me.  There's a reason I'm using Douglas Fir, even though it's not the optimal for this purpose.  I have found that Cherry, Maple, and Mahogany are all well suited to carving half-hulls, provided the piece is free of defects, and your glued-up blank has grain lines running in the same direction.

 

Thanks for the recommended links!  I will definitely check those out.

Like most old ships, Constitution has only survived by being repaired several times.  These repairs, or rebuilds have each changed her external appearance. 

 

Now that  you have a nicely carved hull you should consider which stage in her long life you wish to represent.  A.J. Fisher was the ultimate in ship model kits during the 1930’s, 40’s, and 50’s so the drawing that you are using probably represents her appearance following her rebuild in the 1920’s. Her boxed in head structure is typical of mid-late Nineteenth Century style.

 

The US Government has a handsome half model of the Civil War Era USS Constellation.  If you can find a photo of this model it might give you an idea for finishing yours.

I hope you meant "Constitution" and not "Constellation", Roger.   The Civil War era Constellation looks nothing like a Revolutionary War-War of 1812 ship.

Kirby, just came across you new half hull. Very nice! Hope to see it when we finally get together as a Club. I do have the Royal Navy

take off of HMS President (USS President). The print is from Royal Museum, Greenwich. Would that be of help?

Tim Murphy

Hi Tim!  Great to hear from you, and looking forward to getting together with everyone when the plague has finished its rounds.  

 

Thanks for the offer - any info is helpful, and multiple angles are always good to see.  One of the interesting problems with this model is that there is so much information out there.  I'm going with the Fisher plans for the most part, even though they are only one snapshot of the ship.  Roger's point above is a good one - the lines don't match the configuration she has now, when we sailed on her a few years ago for the turnaround cruise.  

 

Thankfully, as a half-hull representation, I do feel that I can take a certain amount of license.  I also am less committed because I don't have to choose a rig, or gunport locations, etc, etc.  At this scale, I'm going to get close to her real lines, but not get them completely on.  I'm getting to a point now where faring the hull would require certain stations to be off of the plans, anyway.

No Mark, I meant Constellation.   Kirby was pondering the type of finish to give to his model.  I was suggesting that he finish it like the 1860 period half model of Constellation.  I was not suggesting that the 1860 Constellation resembles Constitition.

 

Kirby's A.J. Fisher plans do reflect Constitution with her mid Nineteenth boxed in head structure.
