I am looking for information on the detail, preferably sketches or drawings of a typical copper plate boiler that may have been used with Bolton and Watt steam engines. The reason I ask is that a friend is building a 90"/2286mm long Museum Model of Robert Fulton's steamboat "The North River of CLERMONT". He is attempting to create a model that is historically correct as possible. We are looking for the details on the firebox end, door etc. This search is extremely urgent as the boat is scheduled for a May delivery to the Clermont Historic Site in Germantown, New York.
From Robert Thurston's account: "The boiler was of the form then used in Watt's engines, and was set in masonry. The condenser was of the size used habitually in land engines, and stood, as was the practice in them, in a large cold-water cistern". There is also a dimensional description of the boiler. It puts the boiler at 20 feet long with an oval cross-section of 8 feet wide x 7 feet tall.
If you can help us out by sending sketches of a boiler the may have been used by Watt and subsequently Fulton it would be greatly appreciated. Timing is critical for this project. Thanking you in advance.
