[AMRadio] Safety wire at a premium?

[CL in NC via AMRadio]

My previous email about the end bells on a DY8 dynamotor can be rotary filed now.  I ended up removing the lead from one of the mystery hold downs since it was damaged at that end and low and behold, a screw head appeared.  That sure is a complicated way to make sure the screws don't back out, guess it took a while to grasp the concept of cross drilling the screw head and running safety wire through it.
