Thanks for the kind words, all. This is going to be slow going, though. In truth, I believe my radar dish is about 4.5mm too large. Worse, the Antipodean engines (like that term), while perfectly rendered from my drawings, need to be done over. The secondaries (round ones) are perfect. However, some idiot (yours truly) made a blow on the dimensions of the primary. And, it's significantly too big.
I feel utterly stupid for the error, as it's something I could easily have checked. But, honestly, I've had the engine plans in the can for more than a year. And, when you've spent as much time on this as I have (well, maybe not "you", but certainly me!) a certain amount of complacency sets in. I imagine I had a fence operation in my CAD program that went unnoticed and error was introduced. Otherwise, I can't explain why it didn't affect the secondaries. Anyhow, like I said, slow going when I make amateur mistakes.
The good news is that I've reassessed (I've done this at least a dozen times, since 2007) all the underside dimensions and they all check out. This involves comparing the real world dimensions of a large sampling of kit parts, located from one end of the undercarriage to the other, and testing them against the raster image that I've scaled to studio size in CAD. For example, the 20mm cannon that makes up an antenna on the radar dish measures 62mm. In CAD the same part measures 62.02mm. You want to make sure you take a good sampling of kit part measures that are perpendicular to one another throughout the length of the model.
This is how I sized the model for the 3D printing that Richard (REL) then turned into the gorgeous casting you all know. Anyway, I'm confident everything will fit once I correct my mistakes (radar dish and primary engine). And, I've already set that in motion.
Eagle1 is the kind Antipodean member who, together with his dad, have done miracles in alloy on both this and the RT project. Unfortunately, I've had to put my RT aside, as S1 is front burner, now.
