Actually, I could have broken all four -- instead of merely three. I
must have come to my sense when I was bearing down on the 4th bolt.

I have a tendency to over-doing anything (such as running my knee to
the point that I needed to have a surgery done on my knee). And
tightening up the bolts too much is one of my tendency. That was the
reason why I bought a torque wrench hoping that using the torque wrench
will prevent me from over-torquing the bolts. Unfortunately, I mistook
60-inch-pounds with 60-feet-pounds, and I ended up over-torquing the
bolts by 12 times. And the fact that the torque wrench that I use is
quite big (designed more for higher torque such as for torquing the
propeller); therefore, I didn't get a good feel of the tension. I have
ordered a 1/4" torque wrench that is designed for lower torque (such as
60-inch-pounds); hopefully, this will prevent me from making a similar
mistake.

Look at the bright side. You are going to have a very well stocked
tool box by the time you are finished with this project. :-)

Eisboch

yes, but will he know how to use any of them.


Wonder where he lives? Maybe he'd loan out those tools on occasion.
