The lathe was built in late 1939 or early 1940. It's a standard model of the Heavy 10, with a 3 ft bed, swinging 10 inch diameter work in front of the saddle, and taking lengths up to about 15 inches (depending on chuck) or about 18 inches between centres, and swings almost 6 inches diameter over the saddle. Home made trays below the main base and legs catch inevitable oil drips, otherwise everything seems to be standard - except the colour !

Spindle is highly finished steel running in the cast iron of the headstock - no bronze or white metal here. Later Heavy 10s can have bearing caps with four holding down screws Underneath spindle oilers (also called side oilers) feed oil to a reservoir, from where wicks lift and filter it into the ideal position below the spindle - where bearing clearance will be at its maximum during heavy cutting.

The bronze drive gear for the backgearing is unusual, but I think it was standard for the Heavy 10. Tumbler reverse gear's lever (below the spindle) is shown in the neutral position - screw cutting and long or cross feed are not operating Large backgear operating lever is at its back-most position - it swings forward to engage the backgear.

Marks on the bed are my mistakes not South Bend's fishtails. After I had the bed planed to remove wear, several machinists told me to "break" the newly planed way surfaces with a scraper to help them retain oil. It's an old wives tale - the scraper marks retain dirt as well as oil and will accelerate future wear, so they shouldn't be there. Feedscrews have small dials, and topslide travel is just too short to turn a full length 2 Morse taper. Chip tray is home made, galvanised steel sheet, with rolled and wired edges, and soldered corner joints to hold oil and coolant drips No, the lathe's not a different colour here, this shot was taken at a different time, with different lighting.

Star shaped knob is the early pattern for the clutch controlling the automatic long and cross feed, later machines have a lever operated clutch.

A relic of the lathe's probable first owner - the British Air Ministry. The ministry was in charge of aircraft production during the second world war and needed to import a mass of new machines to ramp up British arms production. To me it seems very odd that this plate was cast in lots of very solid heavy brass, which was then a strategic material whose usage was controlled "for the war effort". I guess an over enthusiastic civil servant wasn't officially told about this Definitely a non-standard feature. A relic of the lathe's probable first owner - the British Air Ministry.
