Hello all-

I went with the helicoils.  The timeserts do look better, but there was
no way I was going to try to both tap and counterbore.  Given my track
record with tapping, I figured it was going to be challenging enough.


I've never seen a Timesert break, come out with the screw or back out
from vibration.  I've seen all of the above with Helicoil, especially in
aluminum.

I distrust Helicoil so much, I once walked for a week (waiting for the
Timesert kit over a Christmas holiday) rather than using a Helicoil that
was at the auto parts place two blocks away.
