Benson Benli precision backgeared and screwcutting lathe. Note the great depth of the flat-topped, V-edged way bed
Fully machined apron - this example is missing the power feeds' selector lever
The saddle was gibbed to the bed by a tapered wedge - the adjustment point being by a screwed rod and locknuts
To provide an extra-fine feed to the power shaft, the operator could arrange for the drive to be by a flat belt from a pulley carried (rather ingeniously), not on the headstock spindle but on a shaft geared down from it
Tumble-reverse mechanism with spring-loaded indent plunger
Tapered spindle nose with locating keyway
Hole through spindle
Tailstock: located by opposed sunken V-ways running down the bed's centre line
Taper-turning unit
Taper-turning unit: degree set-over graduations
Remains of the original countershaft unit: the claws carried self-adjusting bearing housing - exactly like those employed on the 10-inch Atlas lathe
