Fourth (and hopefully last) in our Oaf's Saga:
So our Oafish hero has worked on Chapter 23 (Engine Installation) on and off since February, 1999. He had previously purchased an engine (O-360-A2A) from AeroSport Power, and an engine mount from one of the mount vendors. He had worked his way through the engine mounting, the firewall installation, most of the cowling installation, the airbox/heat ducts and most of the miscellaneous cables and tubes that venture through the firewall and attach to the engine somewhere. As far as our Oaf's dim bulb of a brain could tell, things had gone basically OK, but there had been a few nagging issues.......
Now the Oaf, being the dufus that we've all come to know (if not love) was having a terrible time integrating all this information into a coherent picture. Since these issues had cropped up intermittently over a long span of time, he didn't have the brain power to associate them with one another - to him they seemed this fog of disconnected bits (sort of like what the World Wide Web seems to the Oaf's father). He hypothesized about each one, guessing that some sort of tolerance stackup had reached out and bit him in each instance (not the Oaf's instance, because the Oaf doesn't even know where he might find his instance, but the problem instances) and that maybe he just needed to be more careful (given his previous experiences, this was not an altogether idiotic hypothesis).
One day, while once more trying to get the lower cowling to fit (and while staring at an incipient interference issue with the engine mount and the oil cooler mount on the firewall), it struck our Oaf like a bolt from the blue - "Hey" (he thought to himself; no, wait - he said it out loud, to no one in particular, since there was no one else in his enchanted garage) "Hey - maybe the engine mount is wrong. Can such a thing be?". He rummaged around in his pile of old drawings, found the engine mount specification drawing, and began to take measurements. He found this a difficult task, as the drawings did not have all defining dimensions on them, but with a bit of hard work, he was able to determine the relationship between the dynafocal donut mount points and the firewall bolt mount points.
"GOOD GRAVY, MAN!" (or words to that general effect) our Oaf thought to himself, as he determined that the dynafocal mount points were approximately 1.25" to 1.5" TOO LOW. This explained EVERY LAST ONE OF THE POSITIONAL ISSUES MENTIONED ABOVE! It wasn't our beloved Oaf's fault (this time) - there's actually some other Oaf out there screwing up too! And our Oaf pays for it!
At any rate, our Oaf contacted the mount manufacturer, who quickly accepted responsibility and promised to replace the mount with a better one (gratis, of course). The manufacturer also said that they now sub-contract thejigging and welding of the mount to a vendor that has made substantially more engine mounts than the previous one did, and that this problem should not occur again.
So, THIS Oaf's story (the story, not the Oaf) actually has a recognizable moral to it (unlike those other stories, which seem less than optimally useful without one).
Do a dimensional check on ALL of your purchased parts - verify that they do, in fact, meet the dimensional specifications on the drawings. In the words of our illustrious ex-president, "Trust, but verify".
