Raglan Miller
Miller cross section   Raglan lathes

Built during from the late 1950s until the late 1960s the Raglan vertical miller was an especially well-made, beautifully-finished and compact machine. It was invariably supplied on the makers braced sheet-steel cabinet stand (with a shallow, welded-on chip tray), that required on 24" x 18" to accommodate. The motor, either a single or 3-phase 1425 r.p.m., or 2-speed 710-1425 r.p.m. 3-phase, was built into the back of the machine and drove the spindle though a variable-speed system of a type also used on the Company's "Little John" lathes. A push-button starter was built into the right-hand face of the main column. Spindle speeds ranged from 380 to 2250 with the 1-speed motor and 180 to 2250 rpm with the 2-speed. The high carbon steel spindle ran in Timken taper roller bearings and had a No. 2 Morse taper, but no down feed, instead the knee, as on a proper, full-sized machine, could be elevated. The 21" x 5.5" table carried three T-slots with a coolant trough at each end (though, usefully, the T-slots ran on past them to maximise the clamping area). The Acme-form feed screws ran through bronze nuts and were fitted with the usual large and clear Raglan micrometer dials with friction setting - unfortunately only one handle was fitted for longitudinal feed, at the right-hand end of the table. The table travel was 12" longitudinally, 4" in traverse and around 8.5 inches vertically - the latter figure also being the maximum clearance between spindle nose and table. The machine was lighter than it looked, around 140 kg, caused in part by the main column being in cast aluminium - an unusual choice for a miller, but in the case completely effective.
Most of these machines were supplied with 3-phase motors and changing them, whilst accommodating the variable-speed drive, used to be particularly awkward. With the advent of electronic 3-phase to 1-phase variable-speed inverters, this problem has been overcome - and even if the mechanical system is worn or damaged, it is a  simple matter to rig up a one-to-one drive and use the electronics to vary the speed. In the photographs below the handle for the variable speed drive is shown in the wrong position - it should be facing forwards whilst a pointed indicator moves across a speed scale (just visible) to its rear.
Selling in 1967 at almost exactly the same price as a Myford Super 7 with screwcutting gearbox and cabinet stand, the Raglan miller, at £199 was an expensive proposition. Adding the parts necessary to make a functioning machine - a Clarkson collet chuck (£13 : 0s : 0d), swivelling-base machine vice (£16 : 7s : 0d), coolant unit and pipes (£27 : 6s : 0d) and Low-volt lighting (£9 : 10s : 0d) brought the total to £258 : 3s : 0d.

The variable-speed control lever and its mounting boss are not original

Well-made, chromium-plated handles and good-sized-sized micrometer dials were both standard.
