Making Connections

New Lucas H52 headlamp spider - 1
New Lucas H52 headlamp spider

The early ’30s Lucas headlamp has no internal wires, but instead uses a ‘spider’ with brass fingers to connect the switch, ammeter and bulb terminals. The original is made from thick pressed card, and the brass fingers, with spring steel supports, are riveted to it. After 80+ years these items are usually in poor condition. I had two, both broken, so have fabricated a replacement using the brass fingers, cleaned and annealed, and a new base made from circuit board material. The reinforcing fingers are shaped from 12 thou shim steel, and the assembly is riveted together with hollow brass rivets.

Oiling the wheels …

Persuading semi-fluid grease, a teaspoon-full at a time, into the gearbox is slow work – but Sloper gearboxes are prone to shedding teeth if the correct lubricant and level is not maintained. This ‘box was missing a tooth when I started the restoration, but I have seen far worse!
