Probably taken at the Simmer East gold mine in Johannesburg, around 1904-12. Evidently the winding or haulage drum suffered damage to its grooves, and the owners were faced with recutting the 'screw threads', but only having a screwcutting lathe designed for turning components of very much smaller diameter. The solution was highly ingenious, turning the drum using a belt, probably driven by a steam engine, and driving the lathe's spindle by a chain from the drum's axle. The lathe spindle then traversed the tool carriage in the usual way via the change gears, selected to give the required screw thread pitch. The lathe has been bolted to something, and weighted down with weights and scrap iron.
