Learning from an owner annual

After 6 years of Mooney ownership I'm doing my first owner assisted
annual.

After 13 years of ownership, this will be the 12th owner assisted annual
for me. Having a fixed gear, fixed pitch prop single makes the job
fairly easy. I do any and all required maintenance with the same wrench
BEFORE bringing the plane in for annual.

But alas, my old friend says this year will be his last. He is in his
80s and hanging up the wrench.

The search begins. It will be difficult to even find someone willing to
do this, let alone finding someone compatible.
