Lathe Bed A one piece massive iron casting of cantilever form incorporating auto-traverse clutch box. The bed is dovetail in form and ground on all faces. A central tee-slot provides a positive and accurate location of the tailstock. A gap in the bed allows for the swinging of a loco wheel or flywheel.
Saddle and Slides The cast iron saddle carries a long steel crosslide, which is tee-slotted to enable the mounting of a wide range of accessories. The crosslide has an etched angular scale 45 ° - 0 - 45 ° to facilitate taper turning should the topslide (R6) be added. All slides are fitted with full-length adjustable gib strips. Hand wheels are of steel and incorporate laser etched, re-set to zero calibration dials.
Headstock and Backgears The headstock is of cast iron and employs a ground steel spindle running in honed bearings split with adjusters for the elimination of tool chatter and wear. An oiler for each bearing is fitted. The spindle is bored to pass 6.7mm and has a no. 0 Morse taper. Drive is via a three stepped cast iron vee pulley. A speed reducing backgear is fitted for the machining of large diameter cast iron and to facilitate screwcutting (when the Auto Traverse Kit (R7) and R45 screwcutting gear set is added).
Tailstock with Off-Set The tailstock is of cast iron and is bored and honed to accommodate the ground steel barrel. The barrel has a no. 0 Morse taper and will selfeject tooling. Locking handles are fitted to both body and barrel. The tailstock may be off-set for the turning of long and shallow tapers.
Countershaft and Pulleys The countershaft consists of a three stepped steel pulley that drives the headstock pulley and a double aluminium reduction pulley for motor drive. A fast action cam is fitted for speed changes and belt tensioning.
