Drummond Hand-operated Shaper

First built when Drummond Brothers were operating from the home address of Arthur Drummond in Pinks Hill, Wood Street, Guildford, the Drummond 7" stroke hand-operated shaping machine was a splendid examples of late Victorian engineering. Protected by patents (GB) 24772 and 24773 dated November 5th 1908 together with 25262 and 25263 of November 9th 1908, it was a very well-made rugged little machine with an automatic feed in both directions and made in early and late forms. Both types were very similar but with the former (a very rare model) having a table 6.5" x 4.5" with 7 inches of horizontal travel, 4.5 inches vertically and - an instant identification point - no T-slots in the table top - 3/8" Whitworth tapped holes being provided instead. The later, much more common version, had both an altered clapper box and a table with a top surface of  8" by 9" with two longitudinal T slots and a circular T slot that allowed the standard-fit, degree-graduated base vice to be rotated. However, these improvements came at the price of a reduction in table travel to 6" horizontally and 3" vertically. One notable and very useful feature was the inclusion of a circular hole through the body of the shaper - below and in line with the ram - that allowed long work to be passed through from the back and very long keyways cut, or machining work carried out part way along the length. The tool post could be swivelled, was marked with degree divisions - and had a travel of 1.5". Costing £7 : 10s : 0d (delivered) when new in 1902 a vice, 3 cutting tools, a spanner and tommy-bar were included with the machine.

Very rare Mk. 1 Drummond shaper with tapped holes in the table top

Drummond Mk. 2 Shaper. Note the traditional shaper cutting tool, designed to allow its cutting edge to be exactly in line with the base of the "clapper box". If the tool edge was positioned in front of its support surface there would tendency for it to "dig in" and increase the depth of cut whilst, if allowed to sit behind the edge, exactly the opposite would happen.
