Portass Model S Lathe

SOLD: Portass Model S Lathe 3" x 12" gap-bed, backgeared and screwcutting with a dog-clutch on the leadscrew. Ingeniously improved and uprated, this Model S must be the best available with the following improvements: a built-on 1-phase motor-countershaft unit and backgear provide 12 spindle speeds; the cross, top slide and leadscrew have all been fitted with beautifully engraved zeroing micrometer dials; a special changewheel bracket has been made to allow a super-fine feed drive to the leadscrew using a combination of V-belts and gearing; both headstock bearings are lubricated from a drip-feed oil reservoir and the top slide is fitted with a travel-locking screw and a 4-way toolpost. Included is a set of screwcutting changewheels, a nearly new 3-jaw chuck, a cutting-tool height-setting gauge and a handle to turn the spindle by hand. £195.
