Boy, that's a problem. I have spent the past 8 years writing a book on Monitor's Engine.
During that time, I did a complete drawing book on every part and it is available free on the internet for you to down load . Go to the bottom of the page on this link and you will see the drawings

There is a Confederate book out covering their ironclads and it's called "Engines of the Rebellion"
No one has done the Monitors that I know of, and my focus was on the USS Monitor only.
Ericsson started it all in 1843 with the engine of the USS Princeton and his "Vibrating Piston Engine."
Then he created his Vibrating Lever Engines in the 1850's and Monitor's " Half Trunk Vibrating Lever Engine " in 1861 ( It's NOT a "side lever engine" , that's a NOAA misnomer ) Monitor had a 40 " bore and 22" Stroke, which stayed with the next ten Monitor type ships. Then because the ships were built bigger, they went to a 48 inch Bore (x 24" ?) and then went to a "V" configuration . The irony of this is The Monitor drew only 10 feet of water ( to fight in southern rivers ) and was a "Shallow draft warship"
But the navy ( like all government work) expanded it's size and displacement until they did not work.
Most people do not realize that The Monitor was the first "Battleship" and was not an"ironclad" although it is called that.
It was all steel construction , armor belted , steam powered- no sails, and had a rotating turret , a revolution in ship construction.
There may be more information somewhere in the National Archives on the other ships.
