That may be what I have to do eventually, but I thought it sounded a little
pricey for a fan blade. Even with a legitimate 30-45 minutes of machine
work to make it fit my motor if it fits the space available.

blade is D252999. The fan is approximately 9.75 inches in diameter. It is
about 1.380 inches tall, and has a concave base. The bore when checked with
a caliper is .650 +/- The motor shaft measures at .660 so there is no doubt
some flaw in my technique.
There is an old grind mark that looks like the fan was balanced when it was
