I have always been in awe of that design.
Recalled having once come across a post making reference to a *.pdf posted at Model-Engineer and found it again.

It is a very interesting and comprehensive article on W.D. Urwick's Metal Master Machine with a great many detailed drawings, including a cross section of the column / triangular key arrangement on p. 16/52 and the ingenious method for actually milling the key on p. 22/52

Bear in mind that the column is 3.50" in diameter with the key being 5" long with with 0.75" adjacent sides.
See the attached photohgraph*.
