Like many modellers, for years I have had one of those cheapo plastic Needlepoint oilers that are available via Amazon, eBay etc. While working on the Princess I noticed that mine appeared to be leaking. I decided to see if I could make a new reservoir and reuse the nozzle end. Using a set of metric thread pitch gauges I was struggling to determine whether the pitch was 6mm x 0.9 or 1.0mm.
I drilled and tapped a piece of nickel rod M6 x 1.0 and tested the nozzle. It didn’t fit. I attempted to rethread it M6 x 1.0 but it then sat at a jaunty angle in the end of the bar.
Before going any further, I counter bored the unthreaded end to 8mm and reamed it. I made a press fit plug from more nickel bar, pressed it in and soldered it for good measure. Then decided to make a new nozzle using only the O ring and the needle from original.
I am really pleased with how it turned out for about an hour’s work.
