A common arrangement for driving a lathe spindle, in either direction at several definite speeds, is to provide a countershaft on which are mounted two fixed pulleys and two loose pulleys to accommodate two driving belts from the main shaft, one of which is open and the other crossed.
Motion in either direction is thereby obtained, and a considerable variation in the speed of rotation can be obtained by providing a cone pulley on the countershaft, which drives the cone pulley secured to the lathe E FIG.
This advanced power unit features water cooling, balancing countershaft, exhaust control valve and reed intake for riding pleasure and constant power.
Several other stand-mounted options were available to replace or compliment the standard intermediate countershaft and further details of these can be found here.
Mounted on the maker's heavy cast-iron stand with chip tray, shelves and a built-on 12-speed all V-belt drive countershaft unit.
