Another beautifully made product from CVA Jigs Moulds & Tools Ltd. of Hove,  Sussex the well-specified and versatile No. 79 was intended for precision milling and die-sinking and advertised from the early 1930s until the early 1950s. As with some other CVA products, the sole selling agents were the well-known dealers E. H. Jones, Machine Tools Ltd. of  Edgware Road, The Hyde. London. NW9.
Standing just over 81 inches high, with a compact footprint of just 20" x 30", the miller had three T-slots in its 25.25" x 9.375" table with 14.5 inches of travel longitudinally and 7.5 inches in and out.  The four (later five) spindle speeds were driven by an "A" section V-belt and ran from 325 to 2900 r.p.m. powered by a 0.75 h.p. 3-phase motor. The head, fitted with both a worm-and-wheel driven fine feed and a quick-action rack-and-pinion drilling quill, was carried on dovetail ram that could be moved forwards and backwards through six inches of travel. The main spindle, fitted with a No. 3 Morse taper nose, ran in an unusually long parallel-bore bronze bush gently tapered on its outside and, being machined longitudinally with a series of slots and a slit right through, was adjustable within its tapered housing. At the top a pair of Hoffman W 13/8 ball thrust races was provided with screw adjustment to take out the end float. Later spindles were fitted with adjustable taper roller bearings at the bottom and an angular contact ball bearing at the top - with threaded collars to adjust the axial preload. To avoid belt pull upsetting the spindle, the pulley (like those on high-class lathes) ran in its own bearings - one ball and one (expensive-to-replace) parallel roller - and drove the spindle through a long key. For the size of spindle the head was massively built, resulting in a very solid feel and a particularly smooth drive. Tilting the head (it could be moved 90 degrees in either direction from vertical) was under the control of a handwheel, positioned towards the rear of the column at the left-hand side, working through a worm-and-wheel gear.
Judging by the number surviving both in the UK and overseas the No. 79 was a popular machine and if any reader has a Type 79 miller, or any literature concerning them. the writer would be very interested to hear from them.
