Wood Lathe

Overview

A wood lathe spins a wood blank about a horizontal axis so a stationary hand tool, braced on a rest, can cut it to a round profile. It is the tool behind turned legs, spindles, bowls, pens and baseball bats: the work moves and the cutter stays put, the reverse of most shop machines. A blank is driven at the headstock and, for spindle work, supported at the tailstock, while the turner shapes it freehand with gouges and chisels.

The machine sits on a rigid Bed & Ways whose machined Machined Ways keep every component aligned. The Headstock drives the work; the Tailstock supports its free end; the Tool Rest & Banjo carries the turning tool; and the Variable-Speed Control sets spindle speed. The whole lathe stands on the Stand at working height, with an accessible On/Off Switch and an emergency stop.

How it works

In the headstock, the Drive Motor turns the Headstock Spindle through a Drive Belt running on Stepped Pulleys. Moving the belt between pulley steps sets a coarse speed band, and the Variable-Speed Control trims within it electronically, large bowl blanks must run slow for safety, small spindles fast for a clean cut. The spindle runs in two bearings, is bored MT2 to take a Drive Center, and is threaded so a Faceplate can bolt a bowl blank on; a Spindle Lock & Index holds and indexes it.

For spindle turning the blank is pinched between the drive center and a Live Center in the Tailstock. The tailstock slides along the ways and its Hand-wheel advances the Quill, a Morse-taper barrel returned by a Coil Spring, to press the live center into the work. The turner rests the tool on the Tool Rest, set just off the spinning blank, and the whole Tool Rest & Banjo banjo clamps anywhere along the bed so the rest can follow the cut. Rigidity is everything: the cast Bed Casting and the mass of the Stand damp the vibration that would otherwise turn a catch into a dig, which is why a wood lathe is built far heavier than its modest power suggests.
