This ended up being fixed by having the badly out-of-round brake drums machined by a local car shop: American Auto Lube & Repair at the SEC of Guadalupe & Cooper in Gilbert, AZ. 480-539-4086. They did the whole job for $43 & it took over an hour.

I know that I could probably taken the drums back to Checker where they were purchased 2 weeks before, but I did not trust them to get it right. They actually started this mess in the first place by screwing up my original equipment drum with a routine turn.

The drums I got from RockAuto.com were also bad. The owner at American Lube & Repair said that he would buy any critical parts at NAPA or CarQuest.
