Steam Tug after Steinhaus (1870)
After his well-known books on wooden sailing ship
construction, Carl-Friedrich Steinhaus published another book on
iron ship-building, which saw its second edition in 1870. This
book is a true textbook, as it provides a number of examples with
stability calculations based on detailed construction material
descriptions and inventories. The text is complemented by lines
drawings, GAs and cross-sections as well as an lithographed
artist's impression. This provides the model builder with a
detailed account of steamships of the time. Exercise No. 5
concerns a steam tug of already somewhat old-fashioned appearance
in 1870. It has a flush deck, no bridge and the boiler is housed
in a dome. Some of the details were only sketchy, as they were not
relevant to the exercise and would have been provided by the
shipbuilding supply trade according to the 'fashion' of the day.
These details were drawn on the basis of contemporary information,
as was the rig and the dinghy. The length was 80 feet Hamburg
measure, which gives a model length of about 41 cm in the chosen
A somewhat novel way of construction was chosen.
The length profile as well as bulkhead-frames were cut from brass
sheet of 0.5 mm and 0.25 mm thickness respectively. The frames
included the stanchions for the bulwark. The spaces between the
frames was filled with an acrylic foam (Rohacell©)
as used in architectural model building. A false deck of aluminium
sheet was cemented on this hull, which then was faired in the
usual way and smoothed with automotive putty. Onto this hull,
strips of 0.1 mm copper sheet were glued to represent the plating.
Rivets were embossed before. Otherwise the construction followed
the usual shipmodelling practices.
