Next up the list:
This one goes as a Big shout out to Bruce! I purchased this D45 Months ago (very early in my Steam Acquisition Disorder)
I am embarrassed to admit I have Never fired it!
We where in the thick of Covid and Nobody had steam oil! I Finally ordered from a vendor that I believe Jan recommended, all the way from Germany.
Waiting 6 weeks for steam oil, this engine was placed on a shelf and more engines blocked it from view...until tonight!!
This D45 runs even better then the not yet run in Jensen 85! I am getting apox 675 RPM out of her at max pump pressure and she will idle down so slow it sounds like a Grandfather clock ticking! I can see the individual power strokes on the flywheel as it ticks over. This is a testament to Bruce's work and also to the more efficient design of the slide valve engine. Bruce electrified this engine and also did several other mods to it, she runs beautifully, and now that I have seen her run on air, I plan to Steam her tommorow. Thanks Bruce!!
Side Note: this engine runs about 6% faster in the anti-clockwise direction, I have long suspected Wilesco engine steam chests are not "always" mounted in the perfect "center" of slide valve, this is one reason I wanted the air pump, I think it's great for performance tuning, without the hiss of steam and no chance of getting burned, I can loose the 2 screws and shift the steam chest back and forth in the clearance of the holes and see if I can get the engine to run the same speed in both directions....Or possibly bias even further in one direction for max power output? I love to experiment.
This test has me thinking the D20 will run on 2.32 PSI as well.
