Rollo Wood Lathe

The same geared-headstock assembly used on the round-bed lathe was also employed on a conventional V-edged flat bed machine that had the option of a hand-cranked drive instead of an electric motor and V-belt pulley -  both the unusual Verschoyle and 'Damaco 5' lathes being fitted with a similar arrangement. However, the height of the headstock on the Elf, and the adjustable position of the hand-crank, allowed it to be mounted anywhere on a bench instead of having to overlap the edge to let the handle swing around. However, unlike the motor-driven version, which had the larger of the two gears gear on the spindle driven from a small gear on the pulley input shaft, the hand-cranked model (in order to obtain a reasonable top speed) had the arrangement reversed in a manner not dissimilar to that employed on old-fashioned hand-driven bench grinders.

The headstock gearing of the hand-crank model was a "reverse" of that fitted to the electric-drive model with, in order to get a reasonable top speed, the smaller of the two gears mounted on the headstock.

A novel if expensive way of giving a small lathe a high top speed. Note, in relation to the mass of the headstock casting, the relatively small size of the spindle bearings and the flywheel fitted to the spindle to smooth out the drive.
