loose arm?

Danny,
I can see that a lock washer would be a good idea. I played a 3 hour gig last night and the arm held it's firmness even with plenty of twisting it back and forth, so I'm guessing that the plastic washer and liquid lockwasher is going to do the trick as well.
Thanks for sharing the secret, me and my Mosrite thank you!

OK, so, one more time for the record......the sequence of pieces are:
Base,_______,_______,_______,________,Arm.....????

In my case from top to bottom:
arm handle (stock)
leather washer (stock)
plastic washer
arm mount (stock) - does this piece has a proper name?
washer (stock)
bolt (stock) w/drop of liquid lockwasher

I removed a paper gasket that was between the leather and the mount.
