Well, it was going great until one of the sink drain lines developed a
leak from corrosion. In the process of fixing that, the disposal got
bumped around so that it was a little loose in the bottom of the sink,
the putty was pretty much shot. I figured there was a good chance it
would leak, so I wanted to remove it to re-putty it. The big diecast
nut that holds the disposal to the sink drain wouldn't come loose. I
finally put enough torque on it, but knew I was risking breaking it,
which is what happened.
