Last night was spent in the workshop, first of all I drilled the hole in the oil tank for the oil return from the gearbox. To avoid getting scrap in the oil tank I pressurized it with shop air. Here the hose fitting is welded in place on top of the tank. My first idea was to fit two drain lines but I had to skip the second one since it would have been placed exactly below the output gear in the gearbox, the reason why that wouldn´t work is because I need to use a snorkel tube to get the wet sump level high enough for the pooled up oil to reach the output bearings. To avoid blowing up the oil tank again I fitted a larger diameter vent in the tank lid, a steel braided hose will lead the smoke away from the jet exhaust so it won´t catch fire. That was the easy part, now for the boring bit. I had to open up the freepower NGV throat area a bit since after finding out that I had made it a bit too narrow, now the throat area is close to 75cm2 which should be equal to a jet nozzle of slightly more than 90mm considering the extra flow restrictions through the NGV and power turbine. Cheers! /Anders

That last pic looks very much like a "3rd stage" NGV from a RR250-C20B....Nice work..!

Thank you Smithy, hopefully the modification will help keep the temps in check during full throttle runs. To get oil to the gearbox I found that a connection fitted on the regulator block would be best, it is upstream the oil filter but Ernie has sponsored me with some really nice steel mesh AN filters that I will fit to the oil hose. Drilled and threaded for an AN4 fitting! Here the regulator is back in place with the added fitting, it turned out very neat IMHO. To avoid damage to the gears and bearings I modified the oil drain plug to hold a neodymium magnet that will capture any metal flake floating around in there. Cheers! /Anders

Hi John, Add enough fancy AN couplings and eventually even a thrown together oil regulator can look good. Cheers! /Anders

Is it up to the jury to decide who wins the cash or is there an additional voting round? Also: congratulations!
