–Used the Foredom on the Russian Overkill detent ball and put the knife back together. Not much of a difference. Will probably buy another and sell this one later.
–Looked at the HOA sprinkler schedule: the guy who repaired the leaks changed it again. Garden is down from where it had been (one hour x three days as opposed to 1.5 hours x five days), so I’ll probably just leave it.
