Dear Editor,
Every Avenger unit spends lots of
time replacing screw inserts on the tur-
ret because they pop out easily when
screws are overtightened. Many inserts
are lost because they aren’t held
securely in place while the epoxy–used
to glue them in–hardens. Before we do
the insert replacement procedure in
Para 14-6 of TM 9-1440-433-24-2, we
start at the bottom.
We’ve found that a 5/16-in diameter
bolt that’s at least 1 1/2 inches long
works perfectly for cleaning out the old
epoxy from an insert hole. Just stick the
bolt in your electric drill and go to work
on the old epoxy.
Another big help has been the sug-
gestion you ran in PS to use a piece of
fiberglass to hold the insert in place
while the epoxy hardens. Can you run
that again for other Avenger crews?
