Frozen Let-Off Rail Fix

[baoli liu]

You can using a heat gun to cook the rail.

Put the letoff rail inside a metal tube(if metal tube
is not available,you can wrap the rail by alminum
foil)

Put the tube on the ground(or other safe place),let
the hot air go through the tube.cook the rail for half
hour or so,the longer the looser.

you can do the key levelling work while the rail is
cooked.
