Tom D. Walshaw (1912–1998) was an engineer, author and contributor to the British magazines Model Engineer and Engineering in Miniature. Many of his magazine contributions and books were authored under the pseudonym Tubal Cain. The pseudonym relates to the Tubal-cain, the biblical metal worker. As Tubal Cain he made over 424 contributions to Model Engineer, beginning in 1971. These were mainly divided between workshop equipment articles and model stationary engine constructional articles. He graduated in mechanical engineering at Loughborough University in 1934. and eventually, after a career in mechanical design, went back to that university in 1943, becoming, after some years, senior lecturer in mechanical engineering. He went on in 1948 to teach at University of Liverpool. In 1952 he was appointed Head of Department of Mechanical, Civil and Electrical Engineering at Darlington College of Technology. His final academic post was Head of Mechanical, Production and Civil Engineering at Lancashire Polytechnic. He gained the first of his many model engineering exhibition awards in 1949. At one point he was editor of the Transactions of the Newcomen Society. Walshaw died on 2 May 1998.
Model stationary steam engine designs
Among his most notable contributions to Model Engineer were constructional series detailing models of steam engines dating from the Industrial Revolution:
- A Vertical Columnar Engine. A model of the "Williamson" engine (serialised in 1976)
- Mary, a four-column beam engine (serialised in 1977)
- Lady Stephanie, six-column tank-bed beam engine
- Georgina, a 19th-century overcrank engine (serialised in 1980–81)
- Boreas, a Crowther-type blast furnace blowing engine (serialised in 1983–84)
- Princess Royal & Goliath: variants on mid-19th century mill engines (serialised in 1984–86)
- Trevithick's Dredger Engine (serialised in 1987–88)
