Smart & Brown Home Page    Model L

Based on a pre WW2 German Boley design this beautifully made precision plain-turning lathe was available as either a precision plain-turning (or second-operation) lathe with a screw-feed compound slide rest or as a production model fitted with lever feeds and a range of  capstan turret heads and cut-off slides. Although the last versions were mounted on fabricated bases, the first were fitted to cast aluminium stands (light enough for one man to lift) and then a much heavier and more rigid cast-iron unit. The headstock was "bullet-proof" and, providing the bearings were lubricated, could be run for years without attention. Two rare versions were also manufactured: a bench model and one equipped with a 2-speed motor and gearbox - the latter being instantly recognisable by a  large stand that extended to the left of the headstock. Model L lathes take up very little room and so make an ideal back-up to a larger screwcutting lathe. 

The superbly-constructed headstock with a fully-hardened spindle running in massive bronze bearings

The late model headstock spindle was hardened all over and ran in precision angular-contact pre-loaded ball bearings at the nose end and a roller bearing at the rear. On the 12-speed models power was transmitted to the spindle by a toothed belt running over two sizes of pulley whilst the 3-speed model retained the original flat belt and 3-step cone pulley.
The 12-speed model had six speeds from 600 to 3000 rpm in open drive - with a 4 : 1 reduction available from the two-speed electric motor to give a slower range suitable for 'threading or reaming' of 150 to 750 rpm.

Late Model L (1970s) on fabricated stand. Dimensionally identical to the earlier models, these machines featured 'squared-off' styling to make them look 'modern'.

Full Capstan Unit with lever-action to the cut-off slide and collet closer.

A very rare (circa 1961) Model L on a "Knee-type Cabinet and fitted with a foot-operated quick-change, spindle-speed gearbox

Turret Slide to take 0.75" tooling with 6 stops for hand or automatic indexing (Part LRST)

Screw-feed cut off slide (Part CWP) with front and rear toolposts and adjustable stops.
This unit was also available with lever feed.
