Headlamp Restoration–Lamp and Plug
Initially bought this relic for the battery box only for assembling a clip-on lamp for recital. Pay not much attention for the lamp, just throw it into my spare part box for a while, as both Bakelite surfaces are full of dents and the metal are in bad shape.
Later dug the lamp out and tried to restore it by soaking in WD40 for a week but in vain, the aluminum filter disc was still jammed with the housing, had to applied the hard way as nothing to lose if failed; to cut open the Bakelite housing by thin X-acto saw, the Bakelite broken into pieces but the filter disc came out.
Glued every small pieces back to shape and fill with autofiller, sand smooth and spray black.
