Well, I screwed up by not responding as I had promised .
I have drawn the entire Engine of the USS Monitor in CAD and the prints are available Free.
I ask that you only use them for your personal self
They are copyrighted, registered and protected as it took 20 years of my time in research . They exist nowhere else
This is a 26 Meg download and has 309 pages laid out for 11 x 17 sheet size if you wish to print them

https://homeshopmachinist.net/resources/downloads/

Then click on the Monitor files

Michael, about the Hamilton clock - I don't know if you're aware of it already, but there is a manual for it available here:

Manual for overhaul, repair and handling of Hamilton ship chronometer with parts catalog

Hello Rich,

Hooray and Congratulations! Here is the definitive and ultimate work on the USS Monitor engine, the new Gold Standard.

A few years ago someone in our community – Devin or perhaps Adam Winger – remarked to me that for this book, you had been sifting through the McCord collection of original USS Monitor drawings at the Stevens Institute archives in New Jersey. This is one of many key resources, but I realized then that this book would be a blockbuster, the ultimate reference.

Thank you for creating it, and thank you for your infinite patience in researching and CADing this book. Can’t wait to pore over it!

All best, Michael


For readers not yet familiar with Rich and his work, here are some links. The third one has more detail about Rich, and some photos of his shop as well. mcg.

Michael, I have finished drawing the entire engine of the USS Monitor.
A little over a month ago, I gave two Lectures at The Mariners Museum in Newport News VA and then donated 2 hard copies
of the book which is titled "Drawings of the U.S.S. Monitor's Engine " They also received a PDF Version.
I am working on getting them on the web - so stay tuned.
Had to go to school to learn CAD and it took 2 1/2 years to do this and is 309 pages
So here is the cover of the book and one of the internal drawings.
I do not intend to make any more hard cover books, and the PDF's are for 11 x 17 sheet size to show details I am still working on the "text" book which will describe the engine and it's functions and that will be a hard cover marketed by the Museum
Rich

Paged through this entire collection — excellent drawings of a 30 foot whaleboat, including a table of offsets and a sail plan. Might have application to other 1896 epoch ships as well. Nice to find good detail on a small boat. Also some good SIDE views of a Hotchkiss 6 pdr. Thank you Cliff.

Drawings going up for the Monitor USS Terror:

A few with turret details, such as https://catalog.archives.gov/id/135835529 but I don't see any of the turret engine.

Thank you Phil, this is a helpful precis on what to look for. The table of offsets would be an especially wonderful find. With the drawings I have I could probably make a model by hand sculpting it, but it would be pure guesswork without at least a central bulkhead. The USS Cinncinnati was a beautiful little ship but it had a "torpedo boat stern," one of those design features that is easier to render with sandpaper than with CAD. Michael

The most likely collection of drawings to have the hull lines would be for the initial ship of the class. Any drawings for subsequent ships in the class would only include changes from the original design. For example, for the 27 ships of the Cleveland class and the subsequent missile conversions there are seven sets of drawings (about 12,000 individual drawings) in the Archives. However, only the drawings for the first ship, the USS Cleveland CL-55, have any drawings of the hull.

The Table of Offsets (if it exists) is much better than the hull lines drawings. The table gives the numeric dimensions of the hull that were actually used in the ways to build the hull. Often the basic Table of Offsets is included on one of the hull line drawings, but sometimes it is found in the "mold loft offsets" in papers included with the drawings.

If you are interested in the hull plating the Table of Sight Edges (in the mold loft offsets data) gives the numeric positions of the edges of the hull plating. This is far more accurate than trying to estimate the three dimensional curved edges of individual plates from flat two dimensional drawings.

I don't know when these tables started to be used, so they might not exist for ships built in the 1800s.

Thank you Cliff. I signed up for the Archive Catalog emailings.

In the USS Monitor library I found and purchased a small packet of drawings for the USS Cincinnati. As you know it was a fast cruiser from the epoch of the Spanish American war. Here is a link:

http://www.navsource.org/archives/04/c7/c0707.jpg

The drawings I received, however, did not include the ship's lines. Great idea to look for the lines of her sister ship. As for the marine chronometer, maybe there is an archive category for ships' instruments. Clearly I will have to visit the archives and learn more about how they are organized. Thanks again for your help, Cliff. Michael

That sounds like it's probably this one: https://catalog.archives.gov/id/53483925

Looks like only 2 drawings from that group are online, neither of which pertain directly to the ship itself. That may mean that there either aren't many in that group, or just that the majority of the drawings weren't "low hanging fruit" for scanning purposes. The other likely source for potentially useful drawings would be the other ship from that class, the USS Raleigh (https://catalog.archives.gov/id/53484828) but it doesn't look like any of those are online yet.

The Hamilton drawings might be in there somewhere, but that's a small enough detail that the warehouse scene from Indiana Jones is probably not a bad mental image - they'd most likely be in some sort of contracting records, or part of a ship's drawing set, or...

One thing that might be worth trying (and also asking about the possibility of email notifications of new search results) would be to inquire at the NARA's History Hub website: https://historyhub.history.gov - the NARA archivists are active in the forum, and I've gotten a number of very helpful responses.

Thanks for the information about the archives, Cliff. I have been intrigued by a cruiser from the late 19th century, the USS Cincinnati. Since they are by now well past “C”, maybe there are fresh scans.

Re this USS Monitor project, and to coin a phrase, it ain’t over ‘til the fat lady sings....!

There is another set of drawings I would like to hunt down. In 1941, Hamilton (the watch company) received a Navy contract to manufacture marine chronometers for US warships. Their chronometer was designated the Hamilton Model 21. There are usually one or two on ebay — they are highly prized and vastly expensive. Here is one:

https://www.ebay.com/itm/Fabulous-Hamil ... Swrblb~t9u

They had a special escapement mechanism that was uncanny in its accuracy. It would be fun to see the drawings and try to figure out why it was so good. And to do a 3d CAD version, of course, starting with access to dimensioned drawings. Michael

No arrangement - I usually just periodically search the NARA ARC using their advanced search (https://catalog.archives.gov/advancedsearch) for engineering drawings in RG 19 with no keywords, and (so far at least) the default ordering of the search results if you don't give it a keyword seems to be the most recently added/updated entries in the catalog.

My understanding is the NARA staff are gradually working their way through scanning the ship drawings (so far, the ones stored flat since they're easier to deal with.) I've noticed a roughly alphabetical progression of new drawings over the months, but it looks like this grouping is the first one they hit that was from a monitor ship.

Any new work on the Monitor CAD model, or has it pretty much reached its finished state?

Cheers,
Cliff

Hello Cliff,
These are really interesting. The date I noticed was 1896.

Do you have (or does there exist) an arrangement with the archives that alerts you by email when a keyword like “monitor” is associated with a fresh scan or update?

I noticed that the NARA has posted a number of scans for the USS Puritan, which was a Monitor class ship:

https://catalog.archives.gov/id/53484794

Rather later vintage than the original Monitor of course, but perhaps some of the details will still be informative.

Thank you Michael for the info !
I looked at Scientific American in 1861 and 62, but not 1863, so I have to do that
I haven't dropped Devin a note yet.
Life has been extremely complicated since my post last month and delayed my response, but this is not the place for that.
Sorry if I mislead you on the condenser, there was only one, but the exhaust manifold had TWO pipes, which meant they had to have a "Y " pipe feeding the condenser.
I need to visit the National Archives in Washington DC to follow up on the drawings if available.
I am working with the Mariners Museum on publishing a book about the Monitor's Engine. Taking a Solidworks Class to help me in that venture !

Erickson built monitors for Russia and Sweden..and a South American country (??)
The Swedish monitor called the SOLVE'
https://en.wikipedia.org/wiki/HSwMS_S%C3%B6lve
https://en.wikipedia.org/wiki/Hildur-class_monitor

It was smaller than the USS Monitor and only carried a single gun
I am Swedish and had a relative check it out for me as I do not read/write Swedish and the Swedish Marine museum did not understand my requests.
My cousin told me they gutted the original engine and used the ship as a barge before it was placed in the museum.
They also have no drawings or details of the original installation, even though John Ericsson is a real hero over there.
