Setup notes and briefing numbers for Spares Lathe.
Headstock, bed and leadscrew details
The Spares Lathe specs page helps buyers work through the machine details needed for parts matching. It keeps the focus on the practical information that supports the right lathe spare.
The key figures on a spares lathe start with centre height, distance between centres, spindle bore and bed width. Buyers also need thread form, leadscrew pitch and gearbox arrangement so replacement nuts, gears and shafts line up correctly. Johannesburg workshop dust and long periods of standing can affect saddle wear, cross slide backlash and lubrication points, so those checks belong with the printed dimensions.
Photographs should show the chuck, tailstock, compound slide and any change wheels supplied with the machine. A close view of the serial plate, spindle nose and feed selectors helps when matching parts that differ across similar models. Missing guards, cracked handles and altered electrics are worth noting before any spare is requested.
Measurements buyers should confirm
For a useful parts enquiry, record the swing over bed, swing over saddle and the taper in the tailstock quill. Note whether the machine is set for metric or imperial threading, and check if the feed rod and leadscrew are both present. Those details narrow down the correct half nuts, bearings, belts and toolpost pieces without guesswork.
Before using the contact form, compare the machine as built against any later modifications such as a replacement motor, non standard chuck backplate or added coolant tray. Include one overall machine photo and one close photo of the worn or missing item. On a spares lathe, that usually matters more than a broad model description on its own.

- Bed length and centre distance
- Threading chart and feed settings
Checks that matter in Gauteng
Machines viewed from Crown Mines often show the sort of wear found in active engineering shops around Johannesburg, where chips, abrasive dust and stop start use leave clear marks on slides and drive components. On a spares lathe, inspect the bed near the chuck end, test apron feeds and look for play in the cross slide screw. Electrical supply details also matter when a machine has been rewired or fitted with a different motor.
If the lathe is heading to the coast, surface protection on bare steel parts needs more attention than it does inland. In Gauteng, dust build-up around changewheels, covers and oil points can hide wear that affects part matching. A brief running check should include spindle speeds, feed engagement and the condition of the tailstock clamp.

Information to send with parts requests
Send the model name, serial number if legible, and the exact component needed, such as half nut, cross slide screw, chuck key or tailstock barrel. Add any measured dimensions from the old part, especially thread pitch, bore size and overall length.
It also helps to mention whether the machine is in daily use, standing idle or being rebuilt for resale. That gives proper context when assessing wear on mating parts and whether one replacement item or a full set is the better fit.
